Abstract
An assembly comprising a crank configured to rotate about an output axis; a first motor configured to rotate a first screw; and a first nut assembly configured to translate along the first screw in response to rotation of the first screw. The first nut assembly is coupled to the crank. The assembly further includes a second motor configured to rotate a second screw; and a second nut assembly configured to translate along the second screw in response to rotation of the second screw. The second nut assembly is coupled to the crank. Translation of the first nut assembly along the first screw is out of phase with translation of the second nut assembly along the second screw.
