ABSTRACT:
A platform movable in a horizontal plane by a plurality of underlying, initially vertical finger assemblies which reciprocate, half of which are driven down while the other half are retracted, and which then are cycled in the reverse fashion. The fingers are coupled to spherical surfaces reacting against reaction plates that can be controllably angled, with the result that the reciprocating fingers not only support the platform, but also move it horizontally by developing horizontal forces as a result of tilting the reaction plates.
