An actuator system includes a frame configured to remain stationary relative to a carriage within the frame and connected to the frame by a flexure assembly configured to constrain the carriage for only linear motion along an axis of the actuator system. A rotary base is configured to receive rotational input. Cross-blade flexures operatively connect the carriage to the rotary base, the cross-blade flexures including a plurality of blade flexures and being oriented at an oblique angle to the rotary base and to the axis of the actuator system. A rotary flexure operatively connects the rotary base to the frame. The cross-blade flexures and the rotary flexure are configured to convert rotary motion of the rotary base into linear motion of the carriage and to maintain axial and lateral stiffness.

An actuator device includes a motor and a reduction device operatively coupled to the motor and oriented about a central axis, the reduction device configured to modify an input angle of rotation provided by the motor to an output angle of rotation. Further included is a rotary flexure mechanism that includes a rotary flexure operatively coupled to an output portion of the reduction device. The rotary flexure mechanism also includes a plurality of flexure blades coupled to the rotary flexure, each of the flexure blades angularly oriented from the central axis. The rotary flexure mechanism further includes a diaphragm flexure pair operatively coupled to the flexure blades, wherein the diaphragm flexure comprises a rotational and in-plane stiffness greater than an axial stiffness resulting in the rotary flexure mechanism being configured to convert a rotational input to an axial translation.
