Disclosed is a method for compensating the position of a robot using a laser measuring instrument by establishing an origin coordinate system; irradiating laser beams onto reflectors and calculating distances to the reflectors; converting the origin coordinate system to an established coordinate system; generating coordinates of an end of a lower tip of a welding gun; calculating a position and posture of the robot; teaching the robot four or more postures; uploading position coordinates of the robot and robot teaching program data to a main computer; determining if an error between CAD data and data modeled through simulation is less than a predetermined value, revising the data if it is not or completing compensation of positions of the welding gun, the robot and the jigs if it is; and downloading the robot teaching program to a robot controller.
