A Robotic Actuator of This Quality *and it’s Open Source*?!? Absolute *LEGEND*.

Love a guy who hits a wall or the same wall and never stops moving towards their goal. Can't wait for more.

A+ for the sense of humor... A++ for adding fails... A+++ for perseverance! Keep up the good work!

To wind a motor coil use a long dull tip syringe tip mounted to a pen shaft. It allows you to "place" the wire between the slots where your fingers don't fit. Try bending it to different shapes if you need. Long sowing needles eyelet bent to a hook could also be used. Ideally, you want to fasten the stator to a fixture so you can use a second hook tool to pull loops into position with one hand while guiding/"paying out" the wire with the syringe tip or needle in the other.

When you pulled apart the copper for a second time I just wanted to give you a hug lol. I’ve had to start over on my unreal engine plugin multiple times and the excitement/frustration is very real. At least in my case, it’s literally just code and not physical labor haha. This is such a cool project, thank you for sharing it!

Great video! A small side note, one thing to keep in mind when using cheap rare earth magnets: Buy in bulk, more than you need! Their Tesla field strength is all over the place, if you want to build high efficiency motors you need to measure and sort those to find similar Tesla strength. If you don't do that you can introduce nasty harmonics confusing your motor driver.

Hitting it with a hammer and ".9 inches is more than enough" had me rolling.

I've watched thousands of build videos and I've never felt this intimidated.

13:15 This is the math equivalent of the “Movie Hacking” lol

Dude you are an absolute legend. Thank you so much for posting your fails. Showing my students that failure is part of the process is so hard to get when people hide there mistakes because internet narcissism or plain old human shame. I loved seeing your try fail cycle and you triumph by keeping the effort moving forward.

That’s so cool! When I was in school for mechanical engineering, there was a single mechatronics elective available only every 2 years- and it filled up in less than 10 seconds after registration opened.. needless to say I didn’t get in. I’m now hopeful that I can learn a lot about robot design on my own time from open source projects like the ones on your project! Thanks for making this available for people like me to tinker with and learn- it’s really awesome

It feels like I've seen a lot of videos of these 3D printed gearboxes lately but this is the first one with this production value I've seen well done
-
With this level of production quality, you deserve wayyyyyy more subs
-
17:42 preach brother ! PREACH
-
I love these exploratory videos so much. Well done, sir!
-
By far the best cycloidal and robots projects in general on yt right now. Very well thought out
-
Nice job. Thanks for showing the attempts that didn't work. Watching you trials made me appreciate the simplicity of the harmonic drive.
-
Ahh.. school, when I could focus on just doing cool things.
-
such amazing production quality, simple and easy to understand yet somehow explains more in such a short time than anywhere else on the internet. awesome idea as well and just amazing video overall. not even 4 minutes in and you definitely deserve a sub!
-
Another awesome project. The world is lucky to have you!
