3D model description

I designed this universal joint from scratch, with the idea to use it in the shoulder / hip joints of a robot dog IΒ΄m working on. (I hope I upload that soon too).

My main motivation was to get a universal joint with two DoF in one place, since that is what we mammals have in out shoulders and hip.

You'll see the design steps I wen though to get to were I am now. It is designed to fit the Tower Pro 9g micro servos

I know the print quality is not the best, sorry for that. The parts were printed with a cheap plastic (that looks like never ends!)

I'll upload new pictures as soon as I print with another (better) PLA.


NOTE: I use aaf.li to manage my links, this allows me to:
- Use shorter links
- Change them in only one place if I see they are broken
- Have a nice dashboard with statistics on their performance
- And all this for free
