The purpose of this study is to review the current application areas of Pneumatics Artificial Muscle (PAM) actuator. This article analyses the result of the ongoing theoretical and experimental research on the operational behavior of pneumatic muscle such as muscle structure, as well as data on the generated forces. The speed of response of PAM actuator mostly depends upon its shape and size, pressure inputs and outputs. All these factors have impact on the overall force which is generated by the PAMs. The force generated by PAM purely depends on the rate of pressure added and removal from the actuator and is contractile in nature upon inflation. PAM actuators find wide applications in various facets of robotic equipments and industrial automation. They are easy to manufacture, low cost and can be integrated with human operations without any large scale safety requirements. © 2011 Asian Network for Scientific Information.
