ABSTRACT:
A control system controls the movement and position of an automated device as it moves along a movement track. The control system comprises a chart extending stationarily transversely adjacent along an operative portion of the movement track which includes a light reflective code uniquely defining each increment of length of the chart. A light source is carried by the movement device for illuminating the chart and creating the reflected optical signals. A camera device is also carried by the movement device and receives the optical signals. Corresponding electrical signals are derived and are utilized by a computer processor to control the position and movement of the movement device. The chart includes a plurality of parallel bars extending along the length of the chart. A portion of the bars define, in binary code, the unique optical signal reflected from each distance increment along the chart. A remaining portion of the bars assure the integrity of the reflected optical signal.
