Pneumatic rubber-actuator

0301221-169

[DEFINITION]
An actuator that performs mechanical work by regulating the air pressure in a rubber chamber.

[DESCRIPTION]
An example of pneumatic rubber-actuator has a rubber cylinder covered with a sleeve made of twisted synthetic fiber cord woven into net form with both ends of the cylinder fixed to metallic members. When the rubber cylinder is pressurized, the cylinder expands diametrally and contracts axially, thus enabling mechanical work to be performed. Compared to other types of actuators of the same size, the pneumatic rubber-actuator has a smaller stroke but is lightweight and can produce a large force. This type of actuator has been experimentally applied to the feet of microrobots to produce a hexapedal walking motion, and to the drive mechanism to produce a human muscular-skeletal mimetic motion system.
