A controlled relative motion system having a base support, an output structure and a plurality of securing links each rotatably connected at a first end thereof to a selected one of the base support and the output structure with a circumferential motion pair of those securing links having each member thereof rotatably connected at an opposite second end thereof to that remaining one of the base support and the output structure so as to have the second end of each member rotate in a corresponding rotation plane. These second ends also rotate about a common symmetry rotation axis perpendicular to the rotation planes. In addition, there is a force imparting member that is coupled to a selected coupling one of said first and second ends of a selected one of said circumferential motion pair of securing links, and is capable of directing said coupling end to rotate.
