Hi there! Please, Explain me the difference between Pin & Revolute Joints. As I noticed they do practically the same work, don't they?

Revolute joint is rotation only. It works like you put a nail into the object and into the wall. The object can rotate, but it can't move because of the nail.

A pin joint is where you have two revolute joints a fixed distance apart. You can see a demo of the joint here in our manual. It requires Silverlight (a plugin like flash). The two red rectangles on the left uses a pin joint.
