<P>PROBLEM TO BE SOLVED: To easily validate positional information by a sensor signal having been invalidated through motor replacement or the like. <P>SOLUTION: A robot 1 has a movable member 32 that is turnable to a support member 31 by motor drive. A visual mark 30 indicating a positional relationship between the support member 31 and the movable member 32 is arranged, the visual mark 30 is photographed by a camera 4 before and after the motor replacement, and a servo motor M is controlled in such a way that the positional relationships of the visual mark 30 before and after the motor replacement become the same based on an image signal from the camera 4. An axial angle θn by a sensor signal after the motor replacement is corrected based on axial angles θref-n, θref-n' corresponding to sensor signals after motor control. <P>COPYRIGHT: (C)2012,JPO&INPIT |
