Method and electronic device for calibrating robot

An electronic device, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions which, when executed by the at least one processing unit, causing the at least one processing unit to:
• obtain at least two sets of positional data of a first reference point in a base coordinate system of the robot, the first reference point fixedly arranged on the external axis, the at least two sets of positional data corresponding to at least two positions of the first reference point during movement of the external axis;
• determine a transformation relationship between the base coordinate system and an user coordinate system of the external axis according to the at least two sets of positional data;
• determine the calibrated user coordinate system based on the base coordinate system and the transformation relationship;
• and
• control the robot to process an object arranged on the external axis under the calibrated user coordinate system.
