摘要:
A new robot‐performance calibration system based on tracking multilaser trilateration has been developed. To realize 1 &mgr;m coordinate accuracy, a beam‐deflecting tracking mechanism with both a ball‐seated bearing and a spherically shaped cat’s eye retroreflector whose refractive index is 2.0 has been developed. The coordinate error and the repeatability of a commercial industrial robot have been verified by the system we developed in a two‐dimensional plane.
