Abstract

An actuator includes a plurality of chambers comprised of an extensible material, the chambers having interior side walls and exterior walls, wherein at least a portion of the interior side wall is separated from an interior side wall of an adjacent chamber; and a strain limiting base; and a channel that fluidically interconnects the plurality of chambers, wherein the interior walls are configured to be more compliant than the exterior walls.
