Scientists and engineers at MIT are striving to change the design of artificial limbs which are difficult to use and extremely painful. Their efforts are benefiting from studies on a very curious insect model: the horsehead grasshopper that can move its limbs without relying on any muscles. They studied denervated grasshopper limbs that were flexed at different angles and found that a “passive joint force” moves limbs to their original positions when flexed.
