Abstract
Actuator assemblies and methods of operating actuator assemblies are provided, in particular with the aim of reducing bearing jitter. In one approach an actuator assembly () is provided which has: a support element (); a movable element () movable relative to the support element; an SMA component () connected between the movable element and the support element and arranged to cause movement of the movable element relative to the support element; a bearing () arranged to guide the movement of the movable element; and a controller () arranged to control energy supplied to the SMA component to thereby cause contraction and/or relaxation of the SMA component and to control movement of the movable element relative to the support element in a first direction so as to provide an actuation function, wherein the controller is arranged to, at least whilst the movable element starts to move in the first direction, control the movable element to cause it to be moving in a second direction orthogonal to the first direction.
