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 valves and compressor. We aim to simplify pneumatic system and proposed a new control method. The developed pneumatic system which is called multiplex pneumatic control system is driven by air resonant vibration remotely without electric wires. This system is configured with an oscillator, resonant valve, and air tube connected to the actuator serially. The system is effective to multi-DOF pneumatic mechatronics system. In this paper, the multiplex pneumatic control system constructed with four resonant valves is applied to the system having four pneumatic cylinders. The independent control of the four pneumatic cylinders is succeeded by using four resonant valves.
