Engines have been using pneumatic actuators to move loads for decades. They are fast, up to 0.5 sec/stroke; powerful, with up to 40,000 lbf behind each stroke; and engineers can easily fine-tune these parameters by adjusting air pressure, valving, and bore size. One of the major advantages of pneumatics over other actuators, namely electromechanical and hydraulic alternatives, is their low cost...
