A new laser tracking measurement theory of"laser beam moving and SMR tracking" is proposed.A miniature wheel-armed Laser Guidance Measuring Robot(LGMR) system is developed based on this theory which can move on the horizontal and bevel surface of measured part.The armed-mechanism kinematics mode of LGMR is established,and the motion characteristics of LGMR are analyzed.Finally,the laser tracker and CMM are used to test the performance of LGMR,the experiment results show that the LGMR can automatically and effectively track laser beam and measure the workpiece.It solves the problem that laser beam is lost.
