Piezoceramic Microactuation for Robotic Space Exploration

From overview: Current approach for realization of small vehicles is evolutionary: through the miniaturization1 of existing wheeled/legged vehicles based on state of the art in miniature actuators and motors. However, such miniaturization does not lend itself to cost reduction concomitant with the size reduction because cost of the individual mobility components goes up by an order of magnitude or more for such miniature motors etc. which often need to be precisely hand assembled. An alternate approach with significant potential advantages, especially when traversing unusual and difficult terrain such as loose granular surfaes, is to imitate the mobility attributes of insects.
