Abstract
Expandable actuators surround a central conduit. Each actuator comprises a bladder that, when fluid is introduced, expands laterally while contracting longitudinally. A restorative spring can be placed inside a bladder and between the two ends to restore the actuator to its original shape as fluid is withdrawn. Multiple actuators can be placed in series to successively inflate and deflate and generate a peristaltic motion. One or more Shape Memory Alloy (SMA) springs can be affixed to one or more restorative springs to cause bending motion.
