| Abstract: |
A pantograph linkage system for use in a manipulating tool comprises a pair of pantographs linked together in parallel. Each pantograph consists of a pair of arms held in a fixed relative orientation and the two arms comprise components of parallel linkages. A tool holder appropriately mounted on the free end of the arms can then be moved in all three dimensions without changing its spatial orientation. Simple straightline input movements are all that is required to effect movement of the tool holder.

I claim:
1. A manipulator comprising a pair of pantographs interconnected to serve as opposed links of a parallelogram linkage, the pantographs in turn having first and second arms each operative as a parallelogram linkage, means for maintaining interconnections of the parallelogram linkages in fixed relative relationships and means for imparting linear input movement in all three dimensions to the pantographs whereby three dimensional movement of a tool or the like suitably secured to the pantographs may be occasioned whilst maintaining its spatial orientation constant.
