Today another episode of Hansel Minutes. Today I'm chatting with Aed Musa. He's a I'm chatting with Aed Musa. He's a I'm chatting with Aed Musa. He's a senior mechanical engineering student at senior mechanical engineering student at senior mechanical engineering student at Purdue University. He's got a fantastic Purdue University. He's got a fantastic Purdue University. He's got a fantastic website at aided musa.com. That's a a website at aided musa.com. That's a a website at aided musa.com. That's a a dmusa.com dmusa.com dmusa.com as well as a really popular YouTube as well as a really popular YouTube as well as a really popular YouTube channel. How are you, sir? channel. How are you, sir? channel. How are you, sir? >> I'm doing great. How about you, Scott? >> I'm doing great. How about you, Scott? >> I'm doing great. How about you, Scott? >> I just love learning about new people >> I just love learning about new people >> I just love learning about new people building amazing stuff and uh I just building amazing stuff and uh I just building amazing stuff and uh I just think that your YouTube is is think that your YouTube is is think that your YouTube is is >> I haven't had so much fun on a person's >> I haven't had so much fun on a person's >> I haven't had so much fun on a person's YouTube since uh there's a gentleman YouTube since uh there's a gentleman YouTube since uh there's a gentleman named Ben Eer who does uh you familiar named Ben Eer who does uh you familiar named Ben Eer who does uh you familiar with Ben Eater and his 6502 project. with Ben Eater and his 6502 project. with Ben Eater and his 6502 project. >> Uh vaguely. Yeah. So, he built a >> Uh vaguely. Yeah. So, he built a >> Uh vaguely. Yeah. So, he built a microprocessor from parts and just like microprocessor from parts and just like microprocessor from parts and just like 7400 series off-the-shelf parts. And 7400 series off-the-shelf parts. And 7400 series off-the-shelf parts. And he's like, "Hey, let's learn about he's like, "Hey, let's learn about he's like, "Hey, let's learn about computers. Let's build one." You know, computers. Let's build one." You know, computers. Let's build one." You know, he's the kind of guy who if you want to he's the kind of guy who if you want to he's the kind of guy who if you want to make something, he'll like, "Let's make something, he'll like, "Let's make something, he'll like, "Let's before we learn about this, let's go before we learn about this, let's go before we learn about this, let's go find some rocks, infuse them with find some rocks, infuse them with find some rocks, infuse them with lightning." And you recently built a lightning." And you recently built a lightning." And you recently built a effectively a Boston Dynamics robot effectively a Boston Dynamics robot effectively a Boston Dynamics robot using rope. Uh, surely this was for some using rope. Uh, surely this was for some using rope. Uh, surely this was for some senior project or some master's degree senior project or some master's degree senior project or some master's degree thesis. Like you must have gotten a thesis. Like you must have gotten a thesis. Like you must have gotten a grade for this, right?

grade for this, right? grade for this, right? >> No, no, no. This was just this is a >> No, no, no. This was just this is a >> No, no, no. This was just this is a hobby for me. This is something I do hobby for me. This is something I do hobby for me. This is something I do outside of school to rewind. outside of school to rewind. outside of school to rewind. >> But aren't you overwhelmed with school? >> But aren't you overwhelmed with school? >> But aren't you overwhelmed with school? How do you have any spare time? I've got How do you have any spare time? I've got How do you have any spare time? I've got kids in school. I've got a kid who's a kids in school. I've got a kid who's a kids in school. I've got a kid who's a sophomore. He has no time to build sophomore. He has no time to build sophomore. He has no time to build robots. robots. robots. >> Yeah. Well, I it's uh it is there's a >> Yeah. Well, I it's uh it is there's a >> Yeah. Well, I it's uh it is there's a lot of late nights. I'll I'll tell you lot of late nights. I'll I'll tell you lot of late nights. I'll I'll tell you that. So, yeah, I don't really have a that. So, yeah, I don't really have a that. So, yeah, I don't really have a lot of free time outside of school and lot of free time outside of school and lot of free time outside of school and building robots, but I I make it work. building robots, but I I make it work. building robots, but I I make it work. Yeah, lots of late nights, lots of Yeah, lots of late nights, lots of Yeah, lots of late nights, lots of >> Yeah, lots of >> Yeah, lots of >> Yeah, lots of >> Does it directly relate to your degree >> Does it directly relate to your degree >> Does it directly relate to your degree and your and your work? Like, are you and your and your work? Like, are you and your and your work? Like, are you basically overflowing with enthusiasm basically overflowing with enthusiasm basically overflowing with enthusiasm for mechanical engineering that even you for mechanical engineering that even you for mechanical engineering that even you do your homework, you do your projects, do your homework, you do your projects, do your homework, you do your projects, and then you build stuff because you and then you build stuff because you and then you build stuff because you just can't stop making. just can't stop making. just can't stop making. >> Well, I don't really get the building >> Well, I don't really get the building >> Well, I don't really get the building experience in class. I mean, yeah, I'm a experience in class. I mean, yeah, I'm a experience in class. I mean, yeah, I'm a mechanical engineering major and, you mechanical engineering major and, you mechanical engineering major and, you know, I'm learning all these cool know, I'm learning all these cool know, I'm learning all these cool things, but I'm not really applying it things, but I'm not really applying it things, but I'm not really applying it in school. So when I go home that gives in school. So when I go home that gives in school. So when I go home that gives me the opportunity to apply it. So it in me the opportunity to apply it. So it in me the opportunity to apply it. So it in me for me it's like a whole world of a me for me it's like a whole world of a me for me it's like a whole world of a of a difference. Um learning in school of a difference. Um learning in school of a difference. Um learning in school and then going back home and building and then going back home and building and then going back home and building robots.

robots. robots. >> Was that disappointing? Did you have >> Was that disappointing? Did you have >> Was that disappointing? Did you have this idea that like by senior year at a this idea that like by senior year at a this idea that like by senior year at a well-known university you'd be making well-known university you'd be making well-known university you'd be making stuff? stuff? stuff? >> Um I wouldn't say it's dis it was >> Um I wouldn't say it's dis it was >> Um I wouldn't say it's dis it was disappointed. Um I mean there are some disappointed. Um I mean there are some disappointed. Um I mean there are some classes where I actually I am building classes where I actually I am building classes where I actually I am building things but I mean for the most part you things but I mean for the most part you things but I mean for the most part you know my entire schedule is just sitting know my entire schedule is just sitting know my entire schedule is just sitting down in lectures and maybe doing labs down in lectures and maybe doing labs down in lectures and maybe doing labs and you know doing recitations and stuff and you know doing recitations and stuff and you know doing recitations and stuff like that and I I I understand that you like that and I I I understand that you like that and I I I understand that you have to you know you have to learn have to you know you have to learn have to you know you have to learn things before you go out and into things before you go out and into things before you go out and into industry and build things. So I I do industry and build things. So I I do industry and build things. So I I do understand that there's a lot of understand that there's a lot of understand that there's a lot of learning that goes involved. There's a learning that goes involved. There's a learning that goes involved. There's a lot of taking notes that go involved, lot of taking notes that go involved, lot of taking notes that go involved, but you know, I'm a very proactive but you know, I'm a very proactive but you know, I'm a very proactive person, so I like to apply things that I person, so I like to apply things that I person, so I like to apply things that I learn like immediately. And, you know, learn like immediately. And, you know, learn like immediately. And, you know, for me, it helps to better stick uh that for me, it helps to better stick uh that for me, it helps to better stick uh that knowledge into my head to when I like knowledge into my head to when I like knowledge into my head to when I like actually go out and and apply it. actually go out and and apply it. actually go out and and apply it. >> Somebody said that the way to get an >> Somebody said that the way to get an >> Somebody said that the way to get an engineer to do something is to tell them engineer to do something is to tell them engineer to do something is to tell them it's not possible. It's called nerd it's not possible. It's called nerd it's not possible. It's called nerd sniping. Have you ever heard that term, sniping. Have you ever heard that term, sniping. Have you ever heard that term, nerd sniping? nerd sniping? nerd sniping? >> I have not heard that term. That's a >> I have not heard that term. That's a >> I have not heard that term. That's a great term.

great term. great term. >> So you you tell someone, you know, you >> So you you tell someone, you know, you >> So you you tell someone, you know, you could build a robot, I guess, but you could build a robot, I guess, but you could build a robot, I guess, but you know, there's a way to do that. Like use know, there's a way to do that. Like use know, there's a way to do that. Like use stepper motors and like this is the way stepper motors and like this is the way stepper motors and like this is the way to build robots and like you don't do it to build robots and like you don't do it to build robots and like you don't do it with rope or you know, whatever. And with rope or you know, whatever. And with rope or you know, whatever. And then you kind of like nerd snipe them so then you kind of like nerd snipe them so then you kind of like nerd snipe them so that they go uh I can't get this concept that they go uh I can't get this concept that they go uh I can't get this concept out of my brain like I cannot function out of my brain like I cannot function out of my brain like I cannot function until I have proven that this is true or until I have proven that this is true or until I have proven that this is true or not true. and you tell them it's not not true. and you tell them it's not not true. and you tell them it's not possible and then they freeze up and possible and then they freeze up and possible and then they freeze up and then they run off and they go and they then they run off and they go and they then they run off and they go and they do the thing. Is that how your brain do the thing. Is that how your brain do the thing. Is that how your brain works? works? works? >> Uh, a little bit. Yeah, a little bit. I >> Uh, a little bit. Yeah, a little bit. I >> Uh, a little bit. Yeah, a little bit. I think I'm Yeah, I'm just I'm fascinated think I'm Yeah, I'm just I'm fascinated think I'm Yeah, I'm just I'm fascinated by just really bizarre things and I by just really bizarre things and I by just really bizarre things and I think that partially comes from comes think that partially comes from comes think that partially comes from comes from the uh the idea that you can't from the uh the idea that you can't from the uh the idea that you can't necessarily do it. So, yeah, like a rope necessarily do it. So, yeah, like a rope necessarily do it. So, yeah, like a rope driven speed reducer that seems pretty driven speed reducer that seems pretty driven speed reducer that seems pretty wacky. And you know, when you when you wacky. And you know, when you when you wacky. And you know, when you when you just hear that, if you don't know what just hear that, if you don't know what just hear that, if you don't know what it is, you're like, how does that how's it is, you're like, how does that how's it is, you're like, how does that how's that supposed to work? You know, rope that supposed to work? You know, rope that supposed to work? You know, rope stretches. It doesn't seem like it's stretches. It doesn't seem like it's stretches. It doesn't seem like it's possible. But yeah, I think for sure I'm possible. But yeah, I think for sure I'm possible. But yeah, I think for sure I'm really driven by the idea that things really driven by the idea that things really driven by the idea that things can't be done and no one's really done can't be done and no one's really done can't be done and no one's really done it or really explored it. So, I am it or really explored it. So, I am it or really explored it. So, I am challenged by that and it kind of challenged by that and it kind of challenged by that and it kind of motivates me to to want to go out and motivates me to to want to go out and motivates me to to want to go out and and prove that it can be done and, you and prove that it can be done and, you and prove that it can be done and, you know, prove people wrong.

know, prove people wrong. know, prove people wrong. So we we are on an audiobased format. So we we are on an audiobased format. So we we are on an audiobased format. Although I might put some of this on Tik Although I might put some of this on Tik Although I might put some of this on Tik Tok. We may not be able to see the Tok. We may not be able to see the Tok. We may not be able to see the robot. Folks can go and look at AID's uh robot. Folks can go and look at AID's uh robot. Folks can go and look at AID's uh website. It's listed right there under website. It's listed right there under website. It's listed right there under latest projects and you can learn about latest projects and you can learn about latest projects and you can learn about this this robot. But help us understand this this robot. But help us understand this this robot. But help us understand are there any gears? Are there any are there any gears? Are there any are there any gears? Are there any stepper motors? Like what do you use stepper motors? Like what do you use stepper motors? Like what do you use that is traditional in robot design and that is traditional in robot design and that is traditional in robot design and what did you use that is non-traditional what did you use that is non-traditional what did you use that is non-traditional when building this dog? when building this dog? when building this dog? >> Yeah. So the traditional things are the >> Yeah. So the traditional things are the >> Yeah. So the traditional things are the the motor. I'm using a brushless motor. the motor. I'm using a brushless motor. the motor. I'm using a brushless motor. Brushless motors are really common in Brushless motors are really common in Brushless motors are really common in robotics. They're really high robotics. They're really high robotics. They're really high efficiency, high speed. And with efficiency, high speed. And with efficiency, high speed. And with brushless motors, you can use FOC brushless motors, you can use FOC brushless motors, you can use FOC controllers, which are field uh that controllers, which are field uh that controllers, which are field uh that stands for field oriented control. And stands for field oriented control. And stands for field oriented control. And so those are just like these really so those are just like these really so those are just like these really fancy controllers that allow you to um fancy controllers that allow you to um fancy controllers that allow you to um have position control, velocity control, have position control, velocity control, have position control, velocity control, and torque control for your motors. And and torque control for your motors. And and torque control for your motors. And it gives it like this this almost it gives it like this this almost it gives it like this this almost springiness, like you can turn the motor springiness, like you can turn the motor springiness, like you can turn the motor and then it'll spring back to place when and then it'll spring back to place when and then it'll spring back to place when you let go. And uh that's really you let go. And uh that's really you let go. And uh that's really important for robots, especially legged important for robots, especially legged important for robots, especially legged robots, because it gives compliance and robots, because it gives compliance and robots, because it gives compliance and it allows you to like dampen or stiffen it allows you to like dampen or stiffen it allows you to like dampen or stiffen the joints of the robot to make it, you the joints of the robot to make it, you the joints of the robot to make it, you know, uh move in in the real world like know, uh move in in the real world like know, uh move in in the real world like a actual animal or like a human would a actual animal or like a human would a actual animal or like a human would and it gives it a very natural gate and and it gives it a very natural gate and and it gives it a very natural gate and uh and very natural movement. Um so uh and very natural movement. Um so uh and very natural movement. Um so that's used in robotics and that's what that's used in robotics and that's what that's used in robotics and that's what I used. I used O drive FOC controllers.

I used. I used O drive FOC controllers. I used. I used O drive FOC controllers. Oji is a popular um FOC controller Oji is a popular um FOC controller Oji is a popular um FOC controller brand. Um what else? No gears. There's brand. Um what else? No gears. There's brand. Um what else? No gears. There's no gears at all. So this is a completely no gears at all. So this is a completely no gears at all. So this is a completely rope driven um I was going to say rope driven um I was going to say rope driven um I was going to say gearing system, but this is completely gearing system, but this is completely gearing system, but this is completely rope driven speed reducer system. And so rope driven speed reducer system. And so rope driven speed reducer system. And so it's it's similar to gears in the sense it's it's similar to gears in the sense it's it's similar to gears in the sense that you have something driving that you have something driving that you have something driving something else, but there's no teeth. So something else, but there's no teeth. So something else, but there's no teeth. So you can't call it gears. They're called you can't call it gears. They're called you can't call it gears. They're called drums. And so if you can imagine like drums. And so if you can imagine like drums. And so if you can imagine like you have two gears, all right, turning you have two gears, all right, turning you have two gears, all right, turning each other and then you take away the each other and then you take away the each other and then you take away the teeth. So now they're just like smooth teeth. So now they're just like smooth teeth. So now they're just like smooth cylinders. And then what's cylinders. And then what's cylinders. And then what's >> Yeah, exactly. Like kind of like a >> Yeah, exactly. Like kind of like a >> Yeah, exactly. Like kind of like a pulley. But even pulleys still have uh pulley. But even pulleys still have uh pulley. But even pulleys still have uh teeth, but these have no teeth at all. teeth, but these have no teeth at all. teeth, but these have no teeth at all. It's just smooth completely. And um It's just smooth completely. And um It's just smooth completely. And um instead of teeth, you have rope. And instead of teeth, you have rope. And instead of teeth, you have rope. And there's like these these spiral grooves there's like these these spiral grooves there's like these these spiral grooves in the the drums to allow the rope to to in the the drums to allow the rope to to in the the drums to allow the rope to to glide around the the drums. And the the glide around the the drums. And the the glide around the the drums. And the the rope is anchored on on both sides of one rope is anchored on on both sides of one rope is anchored on on both sides of one of the drums. And so what what happens of the drums. And so what what happens of the drums. And so what what happens is when you tension the rope, it allows is when you tension the rope, it allows is when you tension the rope, it allows the drums to drive each other. And the drums to drive each other. And the drums to drive each other. And they're they're coupled to each other they're they're coupled to each other they're they're coupled to each other now in the same way that gears are, now in the same way that gears are, now in the same way that gears are, except there's just no teeth.

except there's just no teeth. except there's just no teeth. >> Okay. Are they coupled to each other by >> Okay. Are they coupled to each other by >> Okay. Are they coupled to each other by rope tension? What if the rope slips? I rope tension? What if the rope slips? I rope tension? What if the rope slips? I mean, isn't there an implicit mean, isn't there an implicit mean, isn't there an implicit lateral friction that is impi implying lateral friction that is impi implying lateral friction that is impi implying gearing at some molecular level? But gearing at some molecular level? But gearing at some molecular level? But like if it slips, then you lose like if it slips, then you lose like if it slips, then you lose precision and you don't know where you precision and you don't know where you precision and you don't know where you are in space. are in space. are in space. >> Mhm. Yeah. So, that's a great question. >> Mhm. Yeah. So, that's a great question. >> Mhm. Yeah. So, that's a great question. And when you think of a rope driven And when you think of a rope driven And when you think of a rope driven speed reducer, that's probably like the speed reducer, that's probably like the speed reducer, that's probably like the the I guess the first two questions you the I guess the first two questions you the I guess the first two questions you would think of is a, you know, isn't would think of is a, you know, isn't would think of is a, you know, isn't isn't it going to slip? And then B, well isn't it going to slip? And then B, well isn't it going to slip? And then B, well rope stretches, so aren't you going to rope stretches, so aren't you going to rope stretches, so aren't you going to lose precision precision? And both are lose precision precision? And both are lose precision precision? And both are very valid questions and both are the very valid questions and both are the very valid questions and both are the things that I had to challenge or that I things that I had to challenge or that I things that I had to challenge or that I had to tackle first when I uh when I had to tackle first when I uh when I had to tackle first when I uh when I started this project. But um no, the started this project. But um no, the started this project. But um no, the rope doesn't slip at all. And that's uh rope doesn't slip at all. And that's uh rope doesn't slip at all. And that's uh because of something called the capstand because of something called the capstand because of something called the capstand equations. Um, so the cool thing is that equations. Um, so the cool thing is that equations. Um, so the cool thing is that if you wrap rope around a drum, um, if you wrap rope around a drum, um, if you wrap rope around a drum, um, you're actually exponentially increasing you're actually exponentially increasing you're actually exponentially increasing the amount of friction, uh, that's, uh, the amount of friction, uh, that's, uh, the amount of friction, uh, that's, uh, the the amount of friction force between the the amount of friction force between the the amount of friction force between the the rope and the drum with every the the rope and the drum with every the the rope and the drum with every turn of rope you have. So, uh, I forget turn of rope you have. So, uh, I forget turn of rope you have. So, uh, I forget the exact number, but it's possible to the exact number, but it's possible to the exact number, but it's possible to like hold a ship, the weight of a ship like hold a ship, the weight of a ship like hold a ship, the weight of a ship by wrapping enough turns of rope on a by wrapping enough turns of rope on a by wrapping enough turns of rope on a drum with just like human force, a human drum with just like human force, a human drum with just like human force, a human level of force. And that's kind of crazy level of force. And that's kind of crazy level of force. And that's kind of crazy if you think about it, but the math if you think about it, but the math if you think about it, but the math works out. Um, so yeah, there's no slip.

works out. Um, so yeah, there's no slip. works out. Um, so yeah, there's no slip. And I've designed the the uh the drive And I've designed the the uh the drive And I've designed the the uh the drive in a way that you the the rope is in a way that you the the rope is in a way that you the the rope is anchored onto both drums to further anchored onto both drums to further anchored onto both drums to further increase the amount of friction. And increase the amount of friction. And increase the amount of friction. And yeah, there's just no slip. yeah, there's just no slip. yeah, there's just no slip. >> This seems like one of those magical >> This seems like one of those magical >> This seems like one of those magical things about physics that we all think things about physics that we all think things about physics that we all think like that's not intuitive. Therefore, it like that's not intuitive. Therefore, it like that's not intuitive. Therefore, it must be false. Like like levers, right? must be false. Like like levers, right? must be false. Like like levers, right? like the idea like you make a lever like the idea like you make a lever like the idea like you make a lever slightly longer and it makes the ability slightly longer and it makes the ability slightly longer and it makes the ability to like have a human powered thing, you to like have a human powered thing, you to like have a human powered thing, you know, lever or lever like flip a car know, lever or lever like flip a car know, lever or lever like flip a car over. It's like no, that's not possible. over. It's like no, that's not possible. over. It's like no, that's not possible. So, like I'm imagining someone trying to So, like I'm imagining someone trying to So, like I'm imagining someone trying to stop uh you know those guys on the docks stop uh you know those guys on the docks stop uh you know those guys on the docks that are trying to stop a ship and they that are trying to stop a ship and they that are trying to stop a ship and they go and they do the quick couple of loops go and they do the quick couple of loops go and they do the quick couple of loops to put the big giant rope to stop the to put the big giant rope to stop the to put the big giant rope to stop the ship. And it's like there's some optimal ship. And it's like there's some optimal ship. And it's like there's some optimal number that you've calculated of the number that you've calculated of the number that you've calculated of the number of turns. number of turns. number of turns. >> Three is fine. Four is too many. It's >> Three is fine. Four is too many. It's >> Three is fine. Four is too many. It's just not necessary. It's overkill and just not necessary. It's overkill and just not necessary. It's overkill and you've figured that out. you've figured that out. you've figured that out. >> Yeah. Yeah. I mean, you could probably >> Yeah. Yeah. I mean, you could probably >> Yeah. Yeah. I mean, you could probably go out and try it at home. If you grab go out and try it at home. If you grab go out and try it at home. If you grab some some rope, maybe like a pair of some some rope, maybe like a pair of some some rope, maybe like a pair of shoelaces, and you you find some sort of shoelaces, and you you find some sort of shoelaces, and you you find some sort of drum, some sort of cylinder, uh maybe drum, some sort of cylinder, uh maybe drum, some sort of cylinder, uh maybe it's like Yeah, just some sort of it's like Yeah, just some sort of it's like Yeah, just some sort of similar cylinder. Wrap it around the similar cylinder. Wrap it around the similar cylinder. Wrap it around the wrap it around the the drum and see how wrap it around the the drum and see how wrap it around the the drum and see how much friction force you can generate.

much friction force you can generate. much friction force you can generate. see if you can pull one end of the rope see if you can pull one end of the rope see if you can pull one end of the rope and if it slips, um, you'll find that and if it slips, um, you'll find that and if it slips, um, you'll find that it's a lot harder to make it slip it's a lot harder to make it slip it's a lot harder to make it slip because of the amount of turns you have because of the amount of turns you have because of the amount of turns you have on that rope or on that drum. on that rope or on that drum. on that rope or on that drum. >> And that sweet spot, that exponential >> And that sweet spot, that exponential >> And that sweet spot, that exponential sweet spot was where it's like, okay, sweet spot was where it's like, okay, sweet spot was where it's like, okay, now I can go and have proportional now I can go and have proportional now I can go and have proportional gearing without gearing. gearing without gearing. gearing without gearing. >> Exactly. Yeah, >> Exactly. Yeah, >> Exactly. Yeah, >> that's crazy. Let me back up and >> that's crazy. Let me back up and >> that's crazy. Let me back up and understand like when this started understand like when this started understand like when this started because you're 20 two 21 you're 21. because you're 20 two 21 you're 21. because you're 20 two 21 you're 21. >> What's your origin story?

Like when did you have this like I must build this and you have this like I must build this and you have this like I must build this and when did it like overpower what I assume when did it like overpower what I assume when did it like overpower what I assume is as we're kids. I probably shouldn't is as we're kids. I probably shouldn't is as we're kids. I probably shouldn't take apart this perfectly good thing. take apart this perfectly good thing. take apart this perfectly good thing. Like I don't know about you, but I took Like I don't know about you, but I took Like I don't know about you, but I took apart the toaster. I have no doubt you apart the toaster. I have no doubt you apart the toaster. I have no doubt you must have been taking apart the remote must have been taking apart the remote must have been taking apart the remote control at the house. control at the house. control at the house. >> Oh yeah.

Lots of uh lots of talking twos that I've got from lots of talking twos that I've got from lots of talking twos that I've got from my parents for uh taking taking things my parents for uh taking taking things my parents for uh taking taking things apart. Yeah, to put it mildly. But yeah, apart. Yeah, to put it mildly. But yeah, apart. Yeah, to put it mildly. But yeah, I I've always just really been intrigued I I've always just really been intrigued I I've always just really been intrigued with building things. Like as a kid, I with building things. Like as a kid, I with building things. Like as a kid, I was really really into arts and crafts.

was really really into arts and crafts. was really really into arts and crafts. Um you know, I remember like the first Um you know, I remember like the first Um you know, I remember like the first day I bought like my first hot glue gun day I bought like my first hot glue gun day I bought like my first hot glue gun from from Walmart and I was just hot from from Walmart and I was just hot from from Walmart and I was just hot gluing a bunch of things together. I gluing a bunch of things together. I gluing a bunch of things together. I don't know. I've just always been don't know. I've just always been don't know. I've just always been fascinating with with like working with fascinating with with like working with fascinating with with like working with my hands. And I remember like one one my hands. And I remember like one one my hands. And I remember like one one for my brother's birthday one year, I I for my brother's birthday one year, I I for my brother's birthday one year, I I built him this like Green Lantern suit built him this like Green Lantern suit built him this like Green Lantern suit out of uh cardboard. You know, I just out of uh cardboard. You know, I just out of uh cardboard. You know, I just always really liked building things. And always really liked building things. And always really liked building things. And um that kind of spiraled into to the um that kind of spiraled into to the um that kind of spiraled into to the world of STEM in middle school when I world of STEM in middle school when I world of STEM in middle school when I got introduced to to 3D printing. And got introduced to to 3D printing. And got introduced to to 3D printing. And yeah, you know, like you said, I've I've yeah, you know, like you said, I've I've yeah, you know, like you said, I've I've taken apart a bunch of things uh in, you taken apart a bunch of things uh in, you taken apart a bunch of things uh in, you know, in my house. I uh my parents had know, in my house. I uh my parents had know, in my house. I uh my parents had this laptop this one time and they in my this laptop this one time and they in my this laptop this one time and they in my defense they weren't using it anymore. defense they weren't using it anymore. defense they weren't using it anymore. They had just like set it apart. It was They had just like set it apart. It was They had just like set it apart. It was a uh it was an old laptop but yeah I a uh it was an old laptop but yeah I a uh it was an old laptop but yeah I took that apart and I think I was trying took that apart and I think I was trying took that apart and I think I was trying to I was trying to build a a laser. to I was trying to build a a laser. to I was trying to build a a laser. >> Okay. You're trying to build a laser >> Okay. You're trying to build a laser >> Okay. You're trying to build a laser with a laptop. How old are you at this with a laptop. How old are you at this with a laptop. How old are you at this point? point? point? >> I think I was this had to have been I >> I think I was this had to have been I >> I think I was this had to have been I was probably around 10. was probably around 10. was probably around 10. >> Okay. 10 years old. So, this is the >> Okay. 10 years old. So, this is the >> Okay. 10 years old. So, this is the thing that I think is so amazing about thing that I think is so amazing about thing that I think is so amazing about like young people in this time that like young people in this time that like young people in this time that we're in. It's like you've effectively we're in. It's like you've effectively we're in. It's like you've effectively been an engineer for like 11 years, like been an engineer for like 11 years, like been an engineer for like 11 years, like for your entire conscious life, right? I for your entire conscious life, right? I for your entire conscious life, right? I assume you've always been wired this way assume you've always been wired this way assume you've always been wired this way and you can't remember not thinking like and you can't remember not thinking like and you can't remember not thinking like this.

It's been it's it's one of those things that's just been of those things that's just been of those things that's just been totally, you know, ingrained in my every totally, you know, ingrained in my every totally, you know, ingrained in my every being. being. being. >> Mhm. Now, why mechanical engineering and >> Mhm. Now, why mechanical engineering and >> Mhm. Now, why mechanical engineering and not software engineering? It seems like not software engineering? It seems like not software engineering? It seems like you're doing actually both. I mean you're doing actually both. I mean you're doing actually both. I mean because you wrote all the software for because you wrote all the software for because you wrote all the software for your inventions. You had to write uh so your inventions. You had to write uh so your inventions. You had to write uh so you you kind of are a full stack you you kind of are a full stack you you kind of are a full stack engineer all the way into the design of engineer all the way into the design of engineer all the way into the design of the physical uh the physical things. Was the physical uh the physical things. Was the physical uh the physical things. Was it are you more physical or do you are it are you more physical or do you are it are you more physical or do you are you equally good at software? you equally good at software? you equally good at software? >> Definitely my skills mostly lie with >> Definitely my skills mostly lie with >> Definitely my skills mostly lie with mechanical design. Um software my mechanical design. Um software my mechanical design. Um software my software skills despite despite software skills despite despite software skills despite despite appearances are are still I think pretty appearances are are still I think pretty appearances are are still I think pretty rudimentary. I think I have a long way rudimentary. I think I have a long way rudimentary. I think I have a long way to go in terms of software skills, but I to go in terms of software skills, but I to go in terms of software skills, but I think yeah, my real skills lie in think yeah, my real skills lie in think yeah, my real skills lie in mechanical design. And I think mechanical design. And I think mechanical design. And I think mechanical engineering for me is like mechanical engineering for me is like mechanical engineering for me is like the the the mechanical engineer is where the we're mechanical engineer is where the we're mechanical engineer is where the we're all hats, I feel. And if if you have a all hats, I feel. And if if you have a all hats, I feel. And if if you have a mechanical engineering uh degree, I mechanical engineering uh degree, I mechanical engineering uh degree, I think it's easy for you to pivot into think it's easy for you to pivot into think it's easy for you to pivot into several different other engineering several different other engineering several different other engineering disciplines. It's a pretty uh it's a disciplines. It's a pretty uh it's a disciplines. It's a pretty uh it's a pretty versatile field and it's it's pretty versatile field and it's it's pretty versatile field and it's it's pretty it's it's kind of open-ended, so pretty it's it's kind of open-ended, so pretty it's it's kind of open-ended, so you can do a lot with it. And so for me, you can do a lot with it. And so for me, you can do a lot with it. And so for me, because I do like all of these aspects because I do like all of these aspects because I do like all of these aspects of engineering, I felt mechanical would of engineering, I felt mechanical would of engineering, I felt mechanical would give me the broadest um uh the broadest give me the broadest um uh the broadest give me the broadest um uh the broadest knowledge and and give me sort of this knowledge and and give me sort of this knowledge and and give me sort of this this vast amount of uh knowledge in in this vast amount of uh knowledge in in this vast amount of uh knowledge in in all these different engineering all these different engineering all these different engineering disciplines.

disciplines. disciplines. >> Yeah. I mean you've got you've got >> Yeah. I mean you've got you've got >> Yeah. I mean you've got you've got material science uh you've got large material science uh you've got large material science uh you've got large scale engineering small scale scale engineering small scale scale engineering small scale engineering uh tolerances you mean engineering uh tolerances you mean engineering uh tolerances you mean you're you're also in a world that's you're you're also in a world that's you're you're also in a world that's different than where I grew up in that different than where I grew up in that different than where I grew up in that you have 3D printing available to you so you have 3D printing available to you so you have 3D printing available to you so the speed at which you can make this the speed at which you can make this the speed at which you can make this like how many times have you made this like how many times have you made this like how many times have you made this robot until you got it to the point robot until you got it to the point robot until you got it to the point where you call it 1.0 now. where you call it 1.0 now. where you call it 1.0 now. >> Um, well, the actual robot itself I just >> Um, well, the actual robot itself I just >> Um, well, the actual robot itself I just made one time, but I started with just a made one time, but I started with just a made one time, but I started with just a single leg and that would took a couple single leg and that would took a couple single leg and that would took a couple prototypes. I'd say I think I built prototypes. I'd say I think I built prototypes. I'd say I think I built probably three prototypes, but even that probably three prototypes, but even that probably three prototypes, but even that isn't the full picture cuz just building isn't the full picture cuz just building isn't the full picture cuz just building the actuator itself, that probably took the actuator itself, that probably took the actuator itself, that probably took maybe 20 different iterations to get maybe 20 different iterations to get maybe 20 different iterations to get right. So yeah, I I kind of start with right. So yeah, I I kind of start with right. So yeah, I I kind of start with like the single uh most unique component like the single uh most unique component like the single uh most unique component in the robot and really iterate on that in the robot and really iterate on that in the robot and really iterate on that and then as I kind of level up and okay, and then as I kind of level up and okay, and then as I kind of level up and okay, I'm going to build a leg and then build I'm going to build a leg and then build I'm going to build a leg and then build the robot, the number of iterations goes the robot, the number of iterations goes the robot, the number of iterations goes down. down. down. >> Mhm.

Um, but right now I am how to build it. Um, but right now I am I am working on a mini version of KA I am working on a mini version of KA I am working on a mini version of KA that is going to be ridiculously cheap. that is going to be ridiculously cheap. that is going to be ridiculously cheap. Um, for a robot that is. But yeah, I'm Um, for a robot that is. But yeah, I'm Um, for a robot that is. But yeah, I'm working on a mini version of KA that is working on a mini version of KA that is working on a mini version of KA that is going to be open source and something going to be open source and something going to be open source and something that people can make at home. But that's that people can make at home. But that's that people can make at home. But that's going to be a lot better than than this going to be a lot better than than this going to be a lot better than than this version. And it's going to still have version. And it's going to still have version. And it's going to still have capstand drives and all, but it's going capstand drives and all, but it's going capstand drives and all, but it's going to be a lot cheaper. Oh, wow. That's to be a lot cheaper. Oh, wow. That's to be a lot cheaper. Oh, wow. That's cool. Um, my my buddy Mark and I for a cool. Um, my my buddy Mark and I for a cool. Um, my my buddy Mark and I for a thing over at Microsoft borrowed a thing over at Microsoft borrowed a thing over at Microsoft borrowed a $25,000 robot from Hello Robot and it's $25,000 robot from Hello Robot and it's $25,000 robot from Hello Robot and it's like an open source robot platform. It's like an open source robot platform. It's like an open source robot platform. It's like a Roomba with a giant arm and it like a Roomba with a giant arm and it like a Roomba with a giant arm and it can open doors and do kind of stuff. But can open doors and do kind of stuff. But can open doors and do kind of stuff. But we were really surprised at like there's we were really surprised at like there's we were really surprised at like there's the mechanical aspect of robots which the mechanical aspect of robots which the mechanical aspect of robots which seems to be very advanced right now, but seems to be very advanced right now, but seems to be very advanced right now, but then the getting them to do stuff and

then the getting them to do stuff and then the getting them to do stuff and see the space around them is kind of a see the space around them is kind of a see the space around them is kind of a mess. like it just spends a lot of time mess. like it just spends a lot of time mess. like it just spends a lot of time scanning and looking around. Is Cara scanning and looking around. Is Cara scanning and looking around. Is Cara blind or can Cara see stuff? And did or blind or can Cara see stuff? And did or blind or can Cara see stuff? And did or is that another different wall that you is that another different wall that you is that another different wall that you have to climb over? have to climb over? have to climb over? >> Oh yeah, Cara is completely blind. I >> Oh yeah, Cara is completely blind. I >> Oh yeah, Cara is completely blind. I mean, she has googly eyes, so maybe not mean, she has googly eyes, so maybe not mean, she has googly eyes, so maybe not that blind, but in terms of, you know, that blind, but in terms of, you know, that blind, but in terms of, you know, uh, computer vision, there's really uh, computer vision, there's really uh, computer vision, there's really none. Um, there is I have an IMU on car none. Um, there is I have an IMU on car none. Um, there is I have an IMU on car just for a bit of stability, but just for a bit of stability, but just for a bit of stability, but everything else is it's just everything else is it's just everything else is it's just teleyoperated. Um, but yeah, the goal in teleyoperated. Um, but yeah, the goal in teleyoperated. Um, but yeah, the goal in the future is with KA Mini and just the future is with KA Mini and just the future is with KA Mini and just regular KA in general is to add more regular KA in general is to add more regular KA in general is to add more more vision and more autonomous more vision and more autonomous more vision and more autonomous capabilities. capabilities. capabilities. >> You said an IMU, that's an inertial >> You said an IMU, that's an inertial >> You said an IMU, that's an inertial measurement unit. Can you talk about why measurement unit. Can you talk about why measurement unit. Can you talk about why that is important in robotics? that is important in robotics? that is important in robotics? >> Oh yeah, for sure. I mean, if you, you >> Oh yeah, for sure. I mean, if you, you >> Oh yeah, for sure. I mean, if you, you know, picture a robot that you build, if know, picture a robot that you build, if know, picture a robot that you build, if it's going out into the world, there's it's going out into the world, there's it's going out into the world, there's so many unknowns. If the robot is so many unknowns. If the robot is so many unknowns. If the robot is walking up a hill, for example, how do walking up a hill, for example, how do walking up a hill, for example, how do you compensate and ensure that the you compensate and ensure that the you compensate and ensure that the robot's not going to tip over and fall?

robot's not going to tip over and fall? robot's not going to tip over and fall? if the robot steps on a on a rock or if the robot steps on a on a rock or if the robot steps on a on a rock or something that is not um part of the something that is not um part of the something that is not um part of the flat ground, how do you ensure that the flat ground, how do you ensure that the flat ground, how do you ensure that the robot stays stable? So, an IMU uh like robot stays stable? So, an IMU uh like robot stays stable? So, an IMU uh like you said, inertial measurement unit, you said, inertial measurement unit, you said, inertial measurement unit, it's a sensor that essentially measures it's a sensor that essentially measures it's a sensor that essentially measures tilt in all three axes. So, if the robot tilt in all three axes. So, if the robot tilt in all three axes. So, if the robot tilts in a certain way, you can measure tilts in a certain way, you can measure tilts in a certain way, you can measure that tilt um and to a pretty high that tilt um and to a pretty high that tilt um and to a pretty high precision depending on the IMU that you precision depending on the IMU that you precision depending on the IMU that you get, but you can measure that tilt and get, but you can measure that tilt and get, but you can measure that tilt and compensate for it. compensate for it. compensate for it. >> Okay? And IMUs can be collections of >> Okay? And IMUs can be collections of >> Okay? And IMUs can be collections of sensors, right? You know, they can be sensors, right? You know, they can be sensors, right? You know, they can be accelerometers, gyroscopes, accelerometers, gyroscopes, accelerometers, gyroscopes, magnetometers. magnetometers. magnetometers. >> And the idea is not to see where it is, >> And the idea is not to see where it is, >> And the idea is not to see where it is, but it's more like I think it's called but it's more like I think it's called but it's more like I think it's called proprioception. You know, when humans proprioception. You know, when humans proprioception. You know, when humans can put their feet on the ground and can put their feet on the ground and can put their feet on the ground and kind of tell if if the earth is moving kind of tell if if the earth is moving kind of tell if if the earth is moving or if they're moving that those kind of or if they're moving that those kind of or if they're moving that those kind of questions can be answered, right? questions can be answered, right? questions can be answered, right? >> Yeah. >> Yeah. >> Yeah. >> Interesting. Is computer vision a space >> Interesting. Is computer vision a space >> Interesting. Is computer vision a space that would you'd be interested in that would you'd be interested in that would you'd be interested in getting involved in or would you if you getting involved in or would you if you getting involved in or would you if you were going to give Cara eyes and let her were going to give Cara eyes and let her were going to give Cara eyes and let her walk around and do stuff? Would you Is walk around and do stuff? Would you Is walk around and do stuff? Would you Is that a different discipline and you'd that a different discipline and you'd that a different discipline and you'd get a team member to help out with that?

get a team member to help out with that? get a team member to help out with that? >> Um, so yeah, I I didn't mention this, >> Um, so yeah, I I didn't mention this, >> Um, so yeah, I I didn't mention this, but Cara Mini is actually going to be my but Cara Mini is actually going to be my but Cara Mini is actually going to be my senior design project. senior design project. senior design project. >> So, congratulations. >> So, congratulations. >> So, congratulations. >> Yeah. Yeah. So, I'm going to be working >> Yeah. Yeah. So, I'm going to be working >> Yeah. Yeah. So, I'm going to be working with a couple other people on making it with a couple other people on making it with a couple other people on making it happen. and you know hope uh haven't happen. and you know hope uh haven't happen. and you know hope uh haven't fully built my team yet but you know we fully built my team yet but you know we fully built my team yet but you know we are planning on getting like people who are planning on getting like people who are planning on getting like people who are outside of my discipline uh outside are outside of my discipline uh outside are outside of my discipline uh outside of like the really mechanical um the of like the really mechanical um the of like the really mechanical um the mechanical part of the the robot and so mechanical part of the the robot and so mechanical part of the the robot and so yeah the the hope is to get people who yeah the the hope is to get people who yeah the the hope is to get people who are you know more software literate and are you know more software literate and are you know more software literate and and can can help with the computer and can can help with the computer and can can help with the computer vision. vision. vision. >> That's going to be huge.

I I I hope I'm going to make sure that my son watches this make sure that my son watches this make sure that my son watches this episode and appreciates the the episode and appreciates the the episode and appreciates the the overachiever because I'm trying to tell overachiever because I'm trying to tell overachiever because I'm trying to tell him you got to take the AP stuff. You him you got to take the AP stuff. You him you got to take the AP stuff. You got to do summer classes. That's going got to do summer classes. That's going got to do summer classes. That's going to save you so much time, which I assume to save you so much time, which I assume to save you so much time, which I assume then means you'll start your master's then means you'll start your master's then means you'll start your master's degree earlier and then bang that out in degree earlier and then bang that out in degree earlier and then bang that out in a year instead of two or three. a year instead of two or three. a year instead of two or three. >> Yeah, exactly. >> Yeah, exactly. >> Yeah, exactly. >> That's fantastic. Do you think you'll go >> That's fantastic. Do you think you'll go >> That's fantastic. Do you think you'll go and become a roboticist or will you go and become a roboticist or will you go and become a roboticist or will you go and make bridges? Like what's your dream and make bridges?

And so, build robots all day doing that. And so, build robots all day doing that. And so, I think, uh, we'll see where the future I think, uh, we'll see where the future I think, uh, we'll see where the future where the future lies. And in a year, where the future lies. And in a year, where the future lies. And in a year, I'll see kind of I'll kind of gauge I'll see kind of I'll kind of gauge I'll see kind of I'll kind of gauge where my channel is and really make that where my channel is and really make that where my channel is and really make that decision then. But yeah, to answer your decision then. But yeah, to answer your decision then. But yeah, to answer your question simply, I just want to build question simply, I just want to build question simply, I just want to build robots all day.

robots all day. robots all day. >> Now, I mentioned that you've got a a >> Now, I mentioned that you've got a a >> Now, I mentioned that you've got a a Patreon. I realize that that's not the Patreon.

I mean, it's just my apartment. Um, so I have I have just my apartment. Um, so I have I have just my apartment. Um, so I have I have three different Bamboo Lab printers. I three different Bamboo Lab printers. I three different Bamboo Lab printers. I have the A1, the A A1 Mini, and the X1 have the A1, the A A1 Mini, and the X1 have the A1, the A A1 Mini, and the X1 Carbon. And if you don't know, Bamboo Carbon. And if you don't know, Bamboo Carbon. And if you don't know, Bamboo Lab, awesome printers. They're super Lab, awesome printers. They're super Lab, awesome printers. They're super fast. I totally recommend them. And I fast. I totally recommend them. And I fast. I totally recommend them. And I don't just say that because they like don't just say that because they like don't just say that because they like sponsor they've sponsored my video, but sponsor they've sponsored my video, but sponsor they've sponsored my video, but like they genuinely are I think the at like they genuinely are I think the at like they genuinely are I think the at the forefront of FDM printing right now the forefront of FDM printing right now the forefront of FDM printing right now and their printers are super affordable.

and their printers are super affordable. and their printers are super affordable. But yeah, uh my printers are like my But yeah, uh my printers are like my But yeah, uh my printers are like my main manufacturing uh method. I have an main manufacturing uh method. I have an main manufacturing uh method. I have an Eligu Saturn 5 uh SLA printer and it's Eligu Saturn 5 uh SLA printer and it's Eligu Saturn 5 uh SLA printer and it's okay. It's it's all right. I don't do a okay. It's it's all right. I don't do a okay. It's it's all right. I don't do a ton of SLA printing just cuz FDM is just ton of SLA printing just cuz FDM is just ton of SLA printing just cuz FDM is just so much faster and I can crank out parts so much faster and I can crank out parts so much faster and I can crank out parts in a fraction of the time that I can in a fraction of the time that I can in a fraction of the time that I can with a SLA printer. But yeah, um I have, with a SLA printer. But yeah, um I have, with a SLA printer. But yeah, um I have, you know, just regular tools, wrench, you know, just regular tools, wrench, you know, just regular tools, wrench, screwdriver, all of that. But yeah, I'd screwdriver, all of that. But yeah, I'd screwdriver, all of that. But yeah, I'd say my bamboos are my uh biggest or my say my bamboos are my uh biggest or my say my bamboos are my uh biggest or my most high-tech tool. most high-tech tool. most high-tech tool. >> Yeah, I've got a P1S. So when you listed >> Yeah, I've got a P1S. So when you listed >> Yeah, I've got a P1S. So when you listed out A1 A1 mini and then you leapt over out A1 A1 mini and then you leapt over out A1 A1 mini and then you leapt over them to the A1 the X1 Carbon rather that them to the A1 the X1 Carbon rather that them to the A1 the X1 Carbon rather that is the that is an amaz I I aspired to is the that is an amaz I I aspired to is the that is an amaz I I aspired to have a carbon at one point but my I've have a carbon at one point but my I've have a carbon at one point but my I've got a highly modded P1S and it is the got a highly modded P1S and it is the got a highly modded P1S and it is the iPhone of printers like everyone iPhone of printers like everyone iPhone of printers like everyone understands that when you start 3D understands that when you start 3D understands that when you start 3D printing you spend most of your time printing you spend most of your time printing you spend most of your time printing stuff for your printer like you printing stuff for your printer like you printing stuff for your printer like you know you're not actually making anything know you're not actually making anything know you're not actually making anything you're just modding the printer and then you're just modding the printer and then you're just modding the printer and then I would spend probably the first 10 I would spend probably the first 10 I would spend probably the first 10 years of 3D printing was just trying to years of 3D printing was just trying to years of 3D printing was just trying to get the like the first layer, right?

get the like the first layer, right? get the like the first layer, right? >> But what's great about Bamboo Labs is >> But what's great about Bamboo Labs is >> But what's great about Bamboo Labs is that you stop messing around with that you stop messing around with that you stop messing around with printing and you just start printing printing and you just start printing printing and you just start printing like like like >> every like it has a really long warm-up >> every like it has a really long warm-up >> every like it has a really long warm-up that first layer like it double checks that first layer like it double checks that first layer like it double checks everything spend 5 minutes and then for everything spend 5 minutes and then for everything spend 5 minutes and then for that five minute upfront cost that five minute upfront cost that five minute upfront cost >> I don't think I've had a failed print in >> I don't think I've had a failed print in >> I don't think I've had a failed print in memory. memory. memory. >> So now you get to be a mechanical >> So now you get to be a mechanical >> So now you get to be a mechanical engineer and not a 3D printer messing engineer and not a 3D printer messing engineer and not a 3D printer messing around. around. around. >> Exactly. Yeah. Yeah. It's it's so cool. >> Exactly. Yeah. Yeah. It's it's so cool. >> Exactly. Yeah. Yeah. It's it's so cool. I mean, I think I forget who exactly who I mean, I think I forget who exactly who I mean, I think I forget who exactly who said this, but you know, I think the said this, but you know, I think the said this, but you know, I think the best way to capture Bamboo Lab is it it best way to capture Bamboo Lab is it it best way to capture Bamboo Lab is it it they their goal is to not make 3D they their goal is to not make 3D they their goal is to not make 3D printing necessarily a hobby, but it's printing necessarily a hobby, but it's printing necessarily a hobby, but it's just they're making it another tool for just they're making it another tool for just they're making it another tool for you. So, you're not becoming a 3D you. So, you're not becoming a 3D you. So, you're not becoming a 3D printing hobbyist necessarily when you printing hobbyist necessarily when you printing hobbyist necessarily when you get a Bamboo Lab printer, cuz you're not get a Bamboo Lab printer, cuz you're not get a Bamboo Lab printer, cuz you're not trying to figure out the best settings trying to figure out the best settings trying to figure out the best settings in your slicing software. You're not, in your slicing software. You're not, in your slicing software. You're not, you know, figuring out the the best you know, figuring out the the best you know, figuring out the the best nozzle size or stuff like that. um nozzle size or stuff like that. um nozzle size or stuff like that. um you're just using it as another tool you're just using it as another tool you're just using it as another tool like you know as a wrench in your in like you know as a wrench in your in like you know as a wrench in your in your worksp in your workspace you know your worksp in your workspace you know your worksp in your workspace you know you're not tuning your wrench every day you're not tuning your wrench every day you're not tuning your wrench every day to figure out the best way to use it to figure out the best way to use it to figure out the best way to use it you're just using it and I think bamboo you're just using it and I think bamboo you're just using it and I think bamboo is doing that with their printers is doing that with their printers is doing that with their printers >> yeah absolutely they're definitely >> yeah absolutely they're definitely >> yeah absolutely they're definitely they're not a sponsor of mine but I tell they're not a sponsor of mine but I tell they're not a sponsor of mine but I tell people at any turn any time buy a buy an people at any turn any time buy a buy an people at any turn any time buy a buy an A1 mini if you want to get started A1 mini if you want to get started A1 mini if you want to get started they're an absolute delight and then you they're an absolute delight and then you they're an absolute delight and then you said FDM fused deposition modeling this said FDM fused deposition modeling this said FDM fused deposition modeling this is of course what they call additive is of course what they call additive is of course what they call additive printing right I I describe it is like printing right I I describe it is like printing right I I describe it is like drawing happy birthday on a cake with drawing happy birthday on a cake with drawing happy birthday on a cake with liquid sugar except you're drawing on a liquid sugar except you're drawing on a liquid sugar except you're drawing on a board with liquid plastic and it is a

So, it was to really design things well. So, it was to really design things well. So, it was a little bit of both, but definitely a a little bit of both, but definitely a a little bit of both, but definitely a lot of a lot of help from from mentors. lot of a lot of help from from mentors. lot of a lot of help from from mentors. >> I need to go and dig around on your >> I need to go and dig around on your >> I need to go and dig around on your YouTube and I don't know if you've done YouTube and I don't know if you've done YouTube and I don't know if you've done any tutorials on that, but like when you any tutorials on that, but like when you any tutorials on that, but like when you know those situations where something know those situations where something know those situations where something breaks and you got to grab the calipers breaks and you got to grab the calipers breaks and you got to grab the calipers and then like do I make this or do I buy and then like do I make this or do I buy and then like do I make this or do I buy one, you know? Or you end up uh on a one, you know? Or you end up uh on a one, you know? Or you end up uh on a website trying to like I've tried to website trying to like I've tried to website trying to like I've tried to print gears cuz sometimes I'll find a print gears cuz sometimes I'll find a print gears cuz sometimes I'll find a toy uh at Goodwill and it's got a broken toy uh at Goodwill and it's got a broken toy uh at Goodwill and it's got a broken gear and I'm like, "All right, I'm going gear and I'm like, "All right, I'm going gear and I'm like, "All right, I'm going to 3D print a replacement gear for to 3D print a replacement gear for to 3D print a replacement gear for this." And I bust out the calipers and this." And I bust out the calipers and this." And I bust out the calipers and try to do it. It'd be interesting to see try to do it. It'd be interesting to see try to do it. It'd be interesting to see uh even a a time lapse of you designing uh even a a time lapse of you designing uh even a a time lapse of you designing something in Autodesk Inventor. Just a a something in Autodesk Inventor. Just a a something in Autodesk Inventor. Just a a request from a fan.

request from a fan. request from a fan. >> Yeah, I'll take that to heart. Uh I >> Yeah, I'll take that to heart. Uh I >> Yeah, I'll take that to heart. Uh I usually in my videos the CAD I I'll do usually in my videos the CAD I I'll do usually in my videos the CAD I I'll do like a two second brush by of Okay, this like a two second brush by of Okay, this like a two second brush by of Okay, this is what is what is what onto the next thing. Yeah. Yeah, for onto the next thing. Yeah. Yeah, for onto the next thing. Yeah. Yeah, for sure. I think that's that would be cool sure. I think that's that would be cool sure. I think that's that would be cool to actually like show my my design to actually like show my my design to actually like show my my design process. Yeah, I think it would be. Uh process. Yeah, I think it would be. Uh process. Yeah, I think it would be. Uh because what what is so exciting about because what what is so exciting about because what what is so exciting about these things, I mean, you've definitely these things, I mean, you've definitely these things, I mean, you've definitely got the YouTube dialed in. Like they're got the YouTube dialed in. Like they're got the YouTube dialed in. Like they're about 20 minutes long. They're well about 20 minutes long. They're well about 20 minutes long. They're well edited, welldesigned. Uh they get great edited, welldesigned. Uh they get great edited, welldesigned. Uh they get great views, but they they just make you feel views, but they they just make you feel views, but they they just make you feel like, "Ah, I could probably do this." It like, "Ah, I could probably do this." It like, "Ah, I could probably do this." It gives me the kind of false confidence gives me the kind of false confidence gives me the kind of false confidence that I think every YouTube every good that I think every YouTube every good that I think every YouTube every good YouTuber should should give someone.
