Study of laser guided measurement robot

A Laser Guiding Measuring Robot (LGMR) based on the new technology of Laser-Guiding, SMR-Tracking has been developed. LGMR can be guided by measuring laser beam to do 3D laser tracking measurement automatically. LGMR consists of a measuring robot and a laser tracker system (LTS). The measuring robot is employed to carry SMR to track the measuring laser beam from LTS. LTS is used to measure 3D position of SMR and then complete the measurement. The CAD model of a measured object can be used to control the measuring laser beam from LTS to point to the measured position. The measuring robot then tarcks the guiding laser beam and drives SMR to the measured position. This paper presents the working principle and system framework of LGMR. The details of the robot design, implement and experiment are also provided. The experiments prove that the proposed LGMR can measure a complicated object automatically by using the CAD model of the measured objects. The developed LGMR makes it possible for LTS to do 3D tracking measurement automatically by using the CAD model of a measured object to guide the measuring robot.
