Abstract: Variable stiffness devices and methods of their use are provided. In some embodiments, a variable stiffness device comprises an inner member defining a compartment for receiving an actuating fluid; an outer member disposed around the inner member; and a granular medium disposed between the inner member and the outer member; wherein the inner member is being moveable in a radial direction from a relaxed state to an expanded state by introducing the actuating fluid into the compartment of the inner member to compress the granular medium against the outer member to increase the stiffness of the device.

Abstract: The present disclosure provides a biologically-inspired robotic device comprising: a first member; a second member pivotably connected to the first member; one or more actuators; and a coupler/decoupler mechanism (CDC) selectively coupling or decoupling of the one or more actuators to the second member, such that, when the one or more actuators are coupled to the second member, the one or more actuators act to pivot the second member relative to the first member.
