Well, I have been googling around for the functionality but I haven't found anything--it is hard to google for the concept. That was why I was looking for the name of the joint--I thought this would help me find something. The joint is some sort of differential gear assembly I would guess...

I did think of flex-cable drives but since the joint will always be 90 degrees I thought some sort of gear box would provide a more efficient coupling. And I thought this may be something that has been done many times before. But, maybe it is less common than I thought.

Thanks for your response Danger. I probably wasn't clear. Maybe this will help. Imagine a robot body with a robotic arm that has a shoulder joint and a shaft for an arm. I want to be able to rotate the arm as one would as if swinging a bowling ball--forward and backward. There would...

I am trying to find the name of a particular type of joint--I assume it has a name since it is pretty common I think. Imagine two shafts (A & B) joined at 90 degrees to one another with a bevel gear. With both shafts in a constant x-y plane, rotating shaft A will cause shaft B to rotate...
