Calibration of long-stroke Cartesian robot

This data is mainly used for the calibration of the long-stroke Cartesian robot.  The position data is measured by Leica Laser Tracker, including the data of the identification of kinematics parameters,  the data of the Gaussian process regression model validation and prediction, and the data that the compensation results based on HTM, HTM+SBD, HTM+GPR, HTM+SBD+GPR model in different position points.
