Accuracy　measurement　is　an　essential　front　step　to　error　compensation　of　industrial　robots.　Different　measurement　methods　have　been　tried　all　the　way　over　the　past　years.　In　this　paper,　we　propose　a　novel　method　to　measure　the　positioning　distance　accuracy　based　on　the　multi-station　technology　of　the　laser　tracer　device.　Compared　with　the　laser　tracker　device,　this　method　is　more　precise　in　measuring　the　coordinate　values　of　the　robot　end-effector.　Besides,　the　laser　tracer　is　more　portable　than　the　laser　tracker.　At　the　last　part,　a　practical　example　is　presented　in　which　we　have　carried　out　in　an　domestic　industrial　robot.
