ABSTRACT:
This is a fluid-operated linear-rotary robot-like actuator reconstructed from a standard fluid cylinder device. The solid piston of the standard cylinder device is replaced with a self-contained vane-operated piston structure formed of spaced piston parts and an interposed vane chamber and in which a vane-operated work piston is rotated. The work piston extends through the forward cylinder head. A second piston rod extends from the rear part of the piston structure through the rear cylinder head and has passages for supplying the vane chamber of the piston with fluid under pressure. Suitable push button and microprocessor control systems, either by push button or automatically, are provided for controlling the operation of the actuator to give combined linear and rotary movement to a robot hand.
