Compliant Structure

A compliant structure comprising:

• a frame;
• a shuttle distant from the frame mounted on a cantilever that is supported by the frame,
• wherein the cantilever with the shuttle is movable transversely to and out of a plane of the frame;
• and
• one or more flexures that connect the cantilever with the frame, wherein the cantilever comprises a body at least in part extending in a first direction which points to the shuttle, and the one or more flexures connect to the shuttle and/or to the cantilever in the vicinity of the shuttle, wherein the flexures are oriented in a second direction, which second direction is generally transverse with respect to the first direction, and wherein the flexures are preloaded causing the flexures to buckle so as to provide a selectable stiffness to the cantilever and to provide the cantilever with a preferential position out of the plane of the frame.
