The system includes a structural mechanism having interconnected structural beams for applying translational forces and movements to position an object held by the structural mechanism. The system has a measuring mechanism to determine, with precision, the actual position and orientation of each structural beam with respect to its attached neighboring structural beam. The structural mechanism includes at least one structural beam and an associated measuring beam. The measuring beam is in contact only with its associated structural beam, the contact being effected through support devices that provide the only physical contact between the structural beam and the associated measuring beam. | |
