After a ton of work I finally got all of the parts printed and an entire leg assembled ready for testing… Or so I thought. . I have a lot of upgrades coming soon so stay tuned.

Are those needle roller bearings on carbon fiber? How does that hold up?
I love this!! Can’t wait to see the next video
Before I thought the motors were the wrong choice but I think I was wrong. Those DC motors could work pretty well with some good drivers. Im used to bargain h-bridges but if you have current sensing you could make something much smarter than just a servo. The design looks really stiff and durable too.
Great video would like to see if the paw would work make it more animal like when walking could be a possibility of opening the doors to other areas.
wow fusion timeline scary
This is great!! Keep it up!! 🎉🎉😂
Keep it simple, then upgrade is the best decision! I am excited about your project – rolling contact joints are the way to go for legged robots <3
This is a very promising looking project. I think the only problem I may see with it in the future, is the foot. Although it is difficult to tell from the video, it looks like it could be a fragile part, which may not last well in walking conditions, especially outdoors. Also, wouldn't the backdriveability of a motor also depend on whether the robot is on or not? I'm not sure if your demonstration was representative of real conditions the actuator would be in
🎉🎉
Using needle roller bearings right on carbon tube like that will fail pretty quickly with any load or use.
Great video
4:07 "and for you, i only have one thing to say"
Wilson: proceeds to prove by moving parts.
Those with something to say: Now we have nothing to say😂😂
Engineering videos this make my happy in a way i cant explain❤
2:39 I….. uh. NM.
I don't really understand the Arduino Pro Mini. Why not just solder the MCU directly to the board? Btw. you might want to use some more modern MCU-s.
Liked, subbed, and algorithm stimulated! 8^D
This lad looks like it'll be quite big when finished, I look forward to seeing it. Always interesting to see hefty ones that can stomp around the house scaring the burglars, rather than just those little table-top robots that are so popular.
Great progress so far, careful about the carbonfiber dust it can be dangerous
Can Bus lolll
Good luck, I can't wait to see where this goes.
It's not all about backdrivability, but inertias!! The fact that the joints are technically backdrivable does not necessarily mean dynamic motions can be easily achieved. I suggest you watch the interview "The World's Safest Humanoid Robots | Eric Jang, 1X Technologies" to learn a little bit more about the implications.
Love the rolling joint design!
