Abstract

A shape memory alloy (SMA) actuator assembly () comprising: a movable part (); a support structure (); one or more SMA wires arranged, on contraction, to tilt the movable part relative to the support structure about two orthogonal axes that are perpendicular to a primary axis (O) of the support structure; and axial translation constrainers () configured to limit axial translation of the movable part relative to the support structure along the primary axis of the support structure, wherein the axial translation constrainers are arranged to prevent all points of the movable part from simultaneously reaching their most extreme position along the primary axis of the support structure allowed by the range of possible tilt of the movable part relative to the support structure.
