Let us take the example of a serial manipulator. It consists of the drive unit which is the controller or the director for that particular manipulator. As a serial manipulator it has got a fixed base and with the help of several links transmission of the mechanical power takes place. And, in between the two links, we have got the joints, so we have got few joints, between several links.
The robotic joint, could be basically of two types, it could be either the linear joint, or there could be rotary joints.
In linear joint, it could be either prismatic joint or sliding joint.
In the rotary joint, we could have the revolute joint, and there could be twisting joint. Now, both are the rotary joints, but basically, there is a difference between these revolute joint and twisting joint.
