Abstract
A lead screw actuator device includes a base configured to support a plurality of actuators. A first bridge is supported by one of the plurality of actuators and a second bridge is supported by another one of the plurality of actuators. A nut is supported by the first bridge and the second bridge and is rotatably coupled to a screw with a sliding contact friction between the screw and the nut. The plurality of actuators generate small movements of the first bridge, the second bridge, and the nut that produce relative rotation between the nut and the screw. A method of making a lead screw actuator device is also disclosed.
