Abstract: Soft actuators are fabricated from materials that enable the actuators to be constructed with an open-celled architecture such as an interconnected network of pore elements. The movement of a soft actuator is controlled by manipulating the open-celled architecture, for example inflating/deflating select portions of the open-celled architecture using a substance such as compressed fluid.
