Abstract

Provided is a system for setting a workpiece Cartesian coordinate system in a robot. In teaching the nose position (TCP) of a working member (tool) mounted on the hand of an articulated robot, the user moves the tool mounted on the hand to teach a reference point, any point on a predetermined axis and a third point defining a plane together with the other two points, whereupon a single coordinate system is specified by the position data indicative of these three points P1, P2, P3. A plurality of tool coordinate systems having a fixed relationship to the reference coordinate system of the robot can be set.
