Abstract
Apparatus for teaching robot station location relative to a work piece apparatus includes an attachment that can be temporarily coupled to the apparatus and positioned in known relationship to the robot station location. A plurality of positional sensors are mounted on the attachment ring, the sensors each configured to produce a signal when a work piece carried by a robot arm is positioned a predetermined distance from the sensor. A signal receiver is configured to receive signals from the sensors and to indicate which of the sensors has produced the signal. The indication may be the activation of an LED display that indicates to an operator what the next movement of the robot arm should be in order to center the work piece with respect to the robot station location.
