One of the major problems of robotics and especially legged machines is the need for high force/torque to weight and high power to weight ratios of the actuators combined with relative low actuation rate.Pneumatic artificial muscles are contractile devices operated by pressurized air. When inflated, they bulge, shorten and thereby generate a contraction force. The force depends on the applied pressure and on the muscle’s length, ranging from an extremely high value at maximum length, i.e. zero contraction, to zero at minimum length or maximum contraction. Because of the one-way force a paired or antagonistic set-up is needed in order to generate a restoring force or movement.
max air pressure: 120 psi
suggested lengths: 6"-30"
