Abstract
A operation program of a robot is simply changed by using a workpiece body without using a master body. The operation program of the robot is corrected by correction data obtained from cameras. When a point of the operation program is desired to be changed to another point, a point on the workpiece body is changed to a changed point. A robot control unit reads the changed point as the coordinate values of the respective axes and changes the same to space coordinate values. Further, the space coordinate values are converted to reference space coordinate values on the master body by an inverse conversion matrix of the correction data. The reference space coordinate values are inversely converted to the coordinate values of respective reference axes. Since the operation program is commanded by the coordinate values of the respective reference axes, the point of the operation program is converted to the another point by using the coordinate values of the respective reference axes. With this method, the operation program can be simply changed without using the master body.
