Title:
METHOD AND ELECTRONIC DEVICE FOR CALIBRATING ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/044614
Kind Code:
A1
Abstract:
A method (400) and an electronic device (300) for calibrating a robot (200) are provided. The method (400) comprises: obtaining at least two sets of positional data of a first reference point (2021) in a base coordinate system of the robot (410), the first reference point (2021) fixedly arranged on the external axis (201), the at least two sets of positional data corresponding to at least two positions of the first reference point (2021) during movement of the external axis (201); determining a transformation relationship between the base coordinate system and an user coordinate system of the external axis (201) according to the at least two sets of positional data (420); determining the calibrated user coordinate system based on the base coordinate system and the transformation relationship (430); and controlling the robot (200) to process an object arranged on the external axis (201) under the calibrated user coordinate system (440). With the method, the external axis (201) can be calibrated automatically. In comparison to the processes of calibration by the operator, errors caused by human factors are eliminated, which can significantly improve the reliability of calibration.
