Abstract
An actuator assembly comprises: first () and second () parts, wherein a primary axis (P) is defined with reference to the second part; a plurality of lengths of shape-memory alloy wire () connected between the first and second parts, wherein the lengths of wire are configured, when selectively powered, to cause three-dimensional movement of the first part relative to the second part; and a mechanism configured, when the lengths of wire are unpowered, to hold the first part in at least one position and/or orientation relative to the second part against the force of gravity for any orientation of the second part.
