Robot calibration is often used synonymic for parametric robot calibration.
Non-parametric robot calibration circumvents the parameter identification. Used with serial robots, it is based on the direct compensation of mapped errors in the work space. Used with parallel robots, non-parametric calibration can be performed by the transformation of the configuration space.
