Abstract
A method of moving a body (23) comprising: coupling a plurality of piezoelectric motors (31, 32) to the body by pressing a coupling region (48) of each of the motors to a surface of the body; controlling at least one of the motors to apply a force parallel (53) to the surface to move the body; and simultaneously controlling at least one of the motors so that its coupling region executes only vibrations that are substantially perpendicular (51) to the surface.
