Abstract
A pointer to teach a robot to repetitively manipulate a brazing nozzle is provided. In a preferred embodiment, the pointer allows the robot to manipulate the brazing nozzle at a preselected work distance away from a surface along a multi-dimensional path on a complex work piece. The pointer includes a base portion for connection with an end of a robot arm. The pointer additionally has a main body having a length inclusive of the base portion approximating the length of the brazing nozzle and the preselected work distance of the brazing nozzle away from the work piece. A contact portion of the pointer is continuous with the main body and is provided for contacting the work piece. The contact portion has two small parallel spaced surface flats. The surface flats of the contact portion are generally aligned in a common plane at the preselected work angle with respect to the robot arm. The flats are separated by a window cut out to allow an operator who is programming the robot to visually inspect an instantaneous surface of the work piece which is juxtaposed by the flats.
