In this paper, an actuation system whose operation is based on three bellows is introduced. After a brief presentation of the principle that underlies the conversion of pneumatic energy into controllable motion, through bellows, some representative examples of similar actuation systems are analyzed. An original experimental stand have been designed and tested. It is composed of a compressor and three servo-valves ensuring controlled pressures for three parallel bellows. The system can reach up to three degrees of freedom and is controlled by a PC through an interface.

Key words: Bellows, actuators, pneumatic
