ABSTRACT:
A spacial mechanism includes an arm having first and second spaced support points. The first and second support points are supported by first and second swivel bearings. The first and second swivel bearings are supported by first and second rotary elements that cause the first and second support points to travel through first and second circular paths. First and second independently controllable motors cause the first and second rotary elements to rotate at selected rates in selected directions. One end of the arm is caused to trace any predetermined pattern in a limited region by appropriately controlling the rotation of the first and second rotary elements. Analogous optical and fluid devices are also disclosed.
