Abstract
A range finder device for monitoring a 3D position of a robot processing tool relative to a tracking device mounted adjacent to the robot processing tool is disclosed. A body attachable to the tracking device supports a laser unit and a camera unit. The laser unit projects a triangulation laser mark on a target area of the processing tool. The mark, a tool center point and a processing area are in a field of view of the camera unit. A control unit controls operation of the laser unit and has an image analyzer circuit for receiving an image signal produced by the camera unit, producing triangulation laser measurement data from the triangulation laser mark in the image signal, generating a signal indicative of the position of the robot processing tool as function of the triangulation laser measurement data, and transmitting the image signal produced by the camera unit.
