Abstract
A rotational motion-positioning apparatus capable of generating rotational movement about three orthogonal rotational axes. A first axial cam and second axial cam are supported by a rotational joint base. A rotational joint is attached between the rotational joint base and a work load support. The work load support has at least one first axial cam follower tracking the first axial cam rotation, thus rotating the work load support about the rotational joint first rotational axis. The work load support has at least one second axial cam follower tracking the second axial cam rotation, thus rotating the work load support about the rotational joint second rotational axis. The rotational joint base is supported by and rotatable about a housing, thus rotating the work load support about the third rotational axis. Three rotational drive unit are attached to the housing to rotate the first axial cam, second axial cam and rotational joint base.
