Abstract

The authors have previously reported on the absolute distance measuring systems being developed at Lockheed Missiles and Space Company for use in space on large erectable satel-lites. One, a two-color CO₂ laser system, has a precision of 0.03 μm (RMS) for aligning optical elements. The second, a HeNe phase modulated system, has a precision of 25 μm for the measurement and control of large antennas. Also, previously reported, a multi-channel relative distance measurement system originally conceived as a vibration sensor for the active (dynamic) control of large space structures. The application of these measuring systems to the positioning and control of robots is discussed. With a single laser measurement system, the control of several robotic stations may be handled and real-time position-ing of both robot arms and workpiece fixtures in three dimensions, with great precision, is possible. Through computer control, the system would lend itself to batch processing with a variety of functions underway at the different work stations. By controlling the position of the tool, minimum precision is required for the robot.
