Just yesterday youtube showed me this video and I thought to myself what a waste it is to use 30 servos for a project like this:

Your solution is so much cooler.

Yep. I thought of this video as well!

This is a much better engineering solution. Only requires 4 motors.

I'm testing a geneva drive (you can see it in the front in the photo), that should allow me to reduce the number of motors even further. I think I can get it down to two, maybe even one.

Wow, never occurred to me before, but this is such an elegant, and simple solution.
