1. A method of measuring objects using a robot, the method comprising:

  • (a) initializing the robot by;

    (1) defining paths of a sensor in a first coordinate system for measuring an object,(2) translating the defined paths into a second coordinate system,(3) determining actual paths of the sensor in the first coordinate system using an external calibrating device,(4) recording a table of the actual paths of the sensor in the first and second coordinate systems, and(5) removing the external calibrating device; and

    (b) measuring an object by;

    (1) measuring at least one object by moving the sensor along the actual sensor path using the robot,(2) periodically measuring a reference body by moving the sensor using the robot to determine a point cloud,(3) comparing the measured point cloud with a previously measured point cloud, and(4) adjusting a robot control to compensate for changes in the kinematics of the robot based on the comparison of the point clouds.
