Abstract

Tracking lasers have potential for the fast, automatic gathering of static calibration data for measuring the position of the end effector for robotic systems. There are two fundamental designs for tracking laser measurement systems. The first uses a tracking laser interferometer, which provides displacement and angular measurement data, giving a polar coordinate measurement. The second provides only angular data, which requires multiple laser units to allow measurement of the position of a target by triangulation. This paper describes the calibration of iMe LaserTrace system, which has the latter configuration. Previous attempts at calibration of the LaserTrace have not achieved the required accuracy. The problems include the non-linear nature o
