Abstract: A motion control system configured to control motion of a load object independent of the load object, includes a main housing having an internal nut secured with respect to a longitudinal axis of the main housing, and a threaded helical gear movably secured within the main housing. The threaded helical gear includes an end configured to be operatively secured to the load object. The helical gear threadably engages the internal nut. One or both of a first frictional force between the helical gear and the nut or a second frictional force between the nut and at least a portion of the main housing provides a resistive force that controls motion of the load object.
