A NEW MODEL WITH COMPENSATION ALGORITHM FOR DISTANCE ERRORS OF ROBOT MECHANISMS

We develop this new model with compensation algorithm and prove the fact that the distance errorcan be used as a description of the absolute position accuracy. Thus the transformation between the measuring coordinate system and the robot base frame can be avoided so that the calibration process of the absolute position accuracies of the robots is simplified. And this advantage makes a new way to thecnhancement of the absolute position accuracies of the robots.
