3D printed robot arm wrist timing belt joint assembly

Mishin Machine 2022-01-24 | Assembly of my inversed timing belt differential robot wrist joint

I used GT2 timing belts and NEMA 17 stepper motors.

Inversed Timing Belt Differential Robot Joint

Mishin Machine 2022-01-18 | I had an idea to make a timing belt differential joint inspired by the video "Inversed Timing Belt transmission" of Gustav Olsson. It is compact, has no backlash, and backdrivable. It can be used on the robotic arm (wrist joint).

It's my first version of this drive with 400mm GT2 timing belts, there is a ratio of 1.6 between the inversed roll pulley and the pitch pulley. I used openbuilds wheels for handling the outer ring – it's quite rigid and has no backlash. There are some places for improvements such as timing belt wearing.

Maybe some kind of industrial robotic arms use similar solutions but I didn't find any. Please let me know if you find anything.

If you like it I'll make an assembly video.

BTW I am not a mechatronics engineer, it's just a hobby.
