Abstract
A soft robotic bending actuator has a stiff layer bonded to a softer layer where the softer layer is a cellular solid with interconnected voids. The softer layer contracts under a negative pressure differential between the internal pressure of the actuator and its environment applied along its axial direction. The contraction results in a bending motion; i.e., an increased curvature away from the stiff layer.
