Abstract

The invention includes a screw actuator. The screw actuator includes a screw having a screw shaft and a screw nut. The screw shaft defines a first longitudinal axis along its length. The screw nut at least partially surrounds the screw shaft. The screw actuator includes a motor having a stator and a rotor. The rotor is mechanically coupled to the screw shaft. The stator at least partially surrounds the rotor. The screw actuator includes a first rigid member having a length dimension oriented along the first longitudinal axis. The screw actuator includes a second rigid member mechanically constrained relative to the first rigid member. The second rigid member is configured to move along a direction of the first longitudinal axis.
