Air Muscle Actuators - Bio-Robotics

Air muscle are soft pneumatic devices ideally suited for robotics and animatronics. Developed in the 1950's by J.L. McKibben, like biological muscles, air muscles contract when activated.Air muscles contract when pressurized with gas air. Simple systems use a small air pump or compressor.  The size of the air muscle and the air pressure determines the weight of the load it can pull when it contracts. Typically air muscles can contact up to twenty five percentage of their elongated length.
