Abstract
A linear to rotary motion converter includes a rigid body having first and second opposing end plates interconnected by at least one rigid crossmember. Each of the end plates is adapted to receive a rolling diaphragm linear actuator to thereby cause linear displacement of the rigid body in an axial direction upon actuation of the rolling diaphragm linear actuators. The linear to rotary motion converter also includes a capstan operably coupled to and located between the end plates such that linear motion of the rigid body caused by actuation of the rolling diaphragm linear actuators is translated to rotational motion of the capstan.
