Abstract

A teaching tool for programming a laser beam using a robot is provided. The teaching tool includes a sensor which emits a low energy laser beam to be focused on to a predetermined point on a masterwork piece, a photoelectric array associated with the sensor for receiving energization from the laser beam, a housing, a source of focused incandescent light so that a programmer can visually observe the point at which the laser beam is focused, a control and comparator circuit receiving signals from the photoelectric array to determined the focal length of the laser beam emitted by the sensor and a diode gate for effecting energization of a signal indicating that the low energy laser beam of said robot will effect optimize work on said workpieces.
