Abstract
An exoskeleton includes first and second supports coupled to an exoskeleton wearer, a joint connecting the first support to the second support and an actuator. The actuator includes a ball screw, a ball nut assembly coupled to the ball screw and first and second tensile members. The ball nut assembly has first and second cord reactors. The first tensile member is routed through the first cord reactor, and the second tensile member is routed through the second cord reactor. Movement of the ball nut assembly along the ball screw in a first direction causes the second support to move relative to the first support in a first rotational direction about the joint. Movement of the ball nut assembly along the ball screw in a second direction causes the second support to move relative to the first support in a second rotational direction about the joint.
