Abstract: Embodiments of the present disclosure relate to a method and an apparatus for calibrating a thermal drift of a robot having at least one robot arms. The method includes detecting, in response to a reference point on the at least one robot arms being moved to a preselected position, an actual position of the reference point; calculating a deviation value between the preselected position and the actual position; and calibrating, based on the deviation value, a planned position or a planned path that the at least one robot arms are intended to move to or move along, to derive a calibrated position or a calibrated path.
