In-situ　intelligent　manufacturing　for　large-volume　equipment　requires　industrial　robots　with　absolute　high-accuracy　positioning　and　orientation　steering　control.　Conventional　robots　mainly　employ　an　offline　calibration　technology　to　identify　and　compensate　key　robotic　parameters.　However,　the　dynamic　and　static　parameters　of　a　robot　change　nonlinearly.　It　is　not　possible　to　acquire　a　robot＇s　actual　parameters　and　control　the　absolute　pose　of　the　robot　with　a　high　accuracy　within　a　large　workspace　by　offline　calibration　in　real-time.　This　study　proposes　a　real-time　online　absolute　pose　steering　control　method　for　an　industrial　robot　based　on　six　degrees　of　freedom　laser　tracking　measurement,　which　adopts　comprehensive　compensation　and　correction　of　differential　movement　variables.　First,　the　pose　steering　control　system　and　robot　kinematics　error　model　are　constructed,　and　then　the　pose　error　compensation　mechanism　and　algorithm　are　introduced　in　detail.　By　accurately　achieving　the　position　and　orientation　of　the　robot　end-tool,　mapping　the　computed　Jacobian　matrix　of　the　joint　variable　and　correcting　the　joint　variable,　the　real-time　online　absolute　pose　compensation　for　an　industrial　robot　is　accurately　implemented　in　simulations　and　experimental　tests.　The　average　positioning　error　is　0.048　mm　and　orientation　accuracy　is　better　than　0.01　deg.　The　results　demonstrate　that　the　proposed　method　is　feasible,　and　the　online　absolute　accuracy　of　a　robot　is　sufficiently　enhanced.　(C)　2017　Society　of　Photo-Optical　Instrumentation　Engineers　(SPIE)
