Abstract
Pneumatic systems are used in several areas, such as industrial machines, rehabilitation tools and medical robots. However, conventional pneumatic systems become complicated because pneumatic systems have many electrical wires. To solve this problem, we have proposed a Multiplex Pneumatic Actuator Drive Method. This method needs two technical challenges; acoustic communication system and power supply device for each local module. In this paper, small control modules have been developed. When air supply line is 2.5[m] long and the air pressure is 600[kPa], the prototype system successfully works to control ten pneumatic actuators independently without any electrical lines. Therefore, prototype system works very well to show the gTeat potential of this proposed system.
