Detailed Description
A revolute joint constrains to bodies to share a common point while they are free to rotate about the point.The relative rotation about the shared point is the joint angle. You can limit the relative rotation with a joint limit that specifies a lower and upper angle. You can use a motor to drive the relative rotation about the shared point. A maximum motor torque is provided so that infinite forces are not generated.
