Actuators for power driven accessories for moving objects, such as vehicle power windows, windshield wipers, vehicle power antennas, power side view mirrors, catheter drivers, curtain moving machines, bi-directional rotary motors, thruster mechanisms that move relative to a reaction surface or that drive a driven member relative to itself, use orthogonal oscillatory transducers cooperatively to drive intermediary elements to move these objects bi-directionally along constrained paths. The actuators may also power a pneumatically driven autonomous robot element using dual pneumatic DSES elements such as planar contact surfaces with an array of apertures which are cyclically switched form a source of compressed air which acts as a lubricant to greatly reduce surface friction to a vacuum source, which acts as a clamping medium increasing contact frictional force. Orthogonal bladders are cyclically pressurized or vented to move a central block relative to a surrounding frame. All cyclic activity is oscillated at the same frequency. Coordination of phase differences relative to the DSES cycles determines the path of the robotic element which can vector anywhere on a smooth planar surface.

[ We claim:] [1.] An apparatus for moving an object bi-directionally along constrained paths comprising at least two orthogonal oscillatory transducers cooperatively driving a plurality of intermediary elements moving said object bi-directionally along said constrained paths, wherein said object is an end-use device, such as for example but not limited to, an automotive vehicle power window, and further wherein said oscillatory transducers are fewer than four discrete transducers operated at frequencies well below ultrasonic frequencies using single contact elements in each repetitive contact-and-move drive sequence.
