This travelling support consists of a T-shaped table 1 of piezoelectric material carrying pairs of electrodes 2, 3 and 4, 5 coated, respectively, onto sections 6 and 7 of table 1. The pairs of electrodes 2, 3 and 4, 5 are mutually insulated at the joint of sections 6 and 7. This allows for independent control of those sections. Table 1 rests on three feet 9, 10 and 11 of which the lower ends rest on a dielectric layer 12 which may be coated onto the bottom surface of the feet or disposed between the feet and the surface of the bench 13 on which the support is to travel. Movement of this support is achieved by selectively controlling section 6 and 7 of table 1 for contraction or expansion.
