The apparatus also includes a plurality of actuators that are located at the base, and each actuator is associated with a respective link member. The apparatus further includes a plurality of tendons, each of which is coupled to an actuator and a respective link member for effecting movement of the link member with respect to the actuator base. At least one tendon is for effecting movement of at least one link member, and passes through the axis of rotation of each joint that is between the distal end of the at least one link member and the actuator base.
