Experimental evaluation of multiplex penumatic control drive

Pneumatic actuators have several advantages, which are high compliance, light weight, safety, and cheapness. However, a pneumatic system is complicated because of electric wires and air supply lines from solenoid valve and compressor. We aim to simplify pneumatic system and proposed a new control method. The developed pneumatic system which is called multiplex pneumatic system is driven by air resonance vibration remotely without electric wires. Valves of the system have different resonance systems inside it each. When many actuators are driven by the valves this system is possible to drive the actuators independently using only one air tube supply. This system will be effective to the pneumatic system having many degrees of freedom. In this paper, in this paper, the experimental evaluation of four prototype valves for independent control is described. In addition the independent control of four pneumatic cylinders using a timesharing method for multi driving is succeeded.
