Development of a Revolving Drive Mechanism for a Robot Manipulator by using Pneumatic Bellows Actuators with Force Sensing Ability.

Journal of the Robotics Society of Japan, 1996
In this paper we describe a new coupled tendon-driven joint mechanism that uses pneumatic bellows actuators. With regard to the mechanism, frames are attached to shafts of the bellows actuators and are connected to one link arm with wire. By making pressure difference between one side chamber of the actuator and the other, the joint revolves.
