Abstract
A system for setting a tool coordinate system brings directions ( , , ) of respective basic axes of the tool coordinate system into coincidence with directions (X, Y, Z) of basic axes of a robot reference coordinate system. A tool center point (TCP) serves as an origin, and the system causes a robot to memorize metric values on each motion axis of the robot at the moment of coincidence as setting information for setting the tool coordinate system. The system uses this setting information as information for subsequent robot motion. With the present invention, the setting of tool coordinates, which was a troublesome operation in the prior art, can be performed easily and accurately through a simple method.
