Abstract
An actuator includes first and second ends defining an axis there between, and at least four inflatable chambers. Each inflatable chamber is resiliently deformable, elongate, and extends axially between the first and second ends and circumferentially about a central core defined between the ends and by the inflatable chambers. A first pair of the four inflatable chambers is contra rotatory about the core to a second pair of the four inflatable chambers. A pressure change in one or more of the inflatable chambers causes motion of the first end relative to the second end. The actuators can be employed in robots or robotic arms.
