<p>A machine system having optical endpoint control and an associated method for monitoring the position of a machine are provided which includes at least one steerable retroreflective system that defines a relatively large effective acceptance angle, typically exceeding 320 °. In particular, the machine system includes a machine capable of movement in at least one direction and a steerable retroreflective system mounted upon the machine, such as upon the end effector of the machine, for movement therewith. The machine system also includes at least one light source for illuminating the retroreflector such that the position of at least a portion of the machine is determinable based upon reflections from the retroreflector. As such, the machine system can make any necessary corrections in the computer control of the machine to accommodate for differences between the anticipated position of the machine and the actual position of the machine.</p> |
