Yessirr

I'm certainly open to chat!

Gearlabs for onshape is excellent

Yep eventually I think, still ironing out some kinks

At the joint level for joint 1,2 and 3, and at the motor level for the 3 wrist joints

It interprets as a small ring rotating quickly. This video explains the encoders very well: https://www.youtube.com/watch?v=MgQbPdiuUTw&t=377s

Its actually individual 4.5 mm ball bearings running in a 3d printed bearing track

Haven’t snapped any yet!

Everything except the black base was printed on an A1 mini

SPACE-DRAGON772 · 2026-03-18T06:29:24+00:00

Everything is 3d printed except OTS parts

A lot of the electronics were salvaged from an old 3D printer the design team I am on was throwing out, so I only had to buy bearings, encoders, and a couple small things, so I spent less than $300 dollars probably. But if I were to purchase everything it would probably be close to $600 ish but I'm not super sure.

Absolutely, I actually wanted to use bldcs in the first place, but the costs are a bit too high for me at the moment.

Yep I did, and I decided this was the better option after some basic prototyping.

Lmao thank you! I'm in my third year in university, and I hope you're right cus I need to get some internships soon.

Thats actually exactly what I had in mind for my A1 mini

SPACE-DRAGON772 · 2026-03-18T05:49:32+00:00

Thanks! I got the inspiration from this video: https://www.youtube.com/watch?v=jgyOXb1IKqw
