A new generation of robots required a new type of actuators. Therefore scientists developed an artificial muscle (pneumatic muscle) which is operating by pressurized air filling a pneumatic bladder. If the bladder is pressurized it expands and pushes against a mesh sleeve. This produces the contractive force of the air muscle. I used the concept of this high-tech product to design my own, very cheap, low-tech pneumatic air muscle. In my installation I am using eight separate muscles, which are connected to eight different poles by ropes. If the muscles are contracting the poles are lifting. Air pressure is generated with a bycicle pump and an empty water tank. The motion produced by the muscles seems very natural.
