Four proximity sensors help to guide mechanical claw into alinement with target fixture. Digital signals are used to sense distance and to aline roll, pitch, and yaw with respect to target before it is grasped. Sixteen sensor-to-operator messages are possible with binary signal system. Similar, more precise alternative presents 75 workable logic states; most precise alternative uses continuous calibrated data from sensors.
