Abstract

A machine such as a machine tool includes a pair of spaced platforms. One platform may mount an operator such as a tool in a spindle, and the other platform may mount an object such as a workpiece. The spaced platforms are joined by six powered and extensible legs joined to the respective platforms by universal joints. The length of the legs is individually manipulated to vary the positions of the platforms and, therefore, the object and operator relative to each other. Four of the legs are arranged into two pairs which are spaced apart to provide between them a part of a corridor for moving the workpiece into a working position. The two legs in each pair may cross each other. The other two legs extend away from each other and provide another part of the corridor between their inboard ends.
