Interesting Robotic Joint design

I came across this on GrabCAD and thought it may be something good to share here to help promote some joint ideas.  I have uploaded it to a workbench on my GrabCAD account as well and am in the process of tinkering around with it, as well as printing off on a 3D printer to play with.

drupp and differential

Interesting, the first stage of that gear looks a whole lot like the Drupp neck, ass be it different,..  the second stage of that design looks like a pretty typical differential gear..  neat stuff.. what are the degrees of movement.. any idea where the motors attach to drive it?

The way the original maker

The way the original maker set it up, the 3 motors driving it are at the top of it.   If you want i can add you to my workbench on GrabCAD so you can split it apart and play around with it. And download in whatever file format you want.
