One of the embodiments of the invention is an actuator system for extending and flexing a joint. The actuator system includes a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism including a screw that accepts the rotational output of the multi-motor assembly and a nut that cooperates with the screw to convert rotational movement of the screw to linear movement of the nut, and a moving rail with a latch that functions to translate linear movement of the nut in both the extension and flexion directions into an extension and flexion of the joint. The actuator has been specifically designed for extending and flexing a joint (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system may, however, be used to move any suitable object through any suitable movement (linear, rotational, or otherwise).
