Problems solved by technology
[0002] At present, when the industrial robot is suddenly powered off and the battery is dead, the zero point may be lost. If the zero mark is set according to the zero mark position on the robot body, the zero position will not be accurate enough. At the same time, if the robot is installed The position is not easy to view the position of the zero mark, which brings difficulties to the robot's zero mark

The invention relates to a robot and a method for calibrating the zero point of a robot. By recording reference deflection angles of all motion axis when the zero point of the robot is calibrated, deflection angles of all the motion axis is adjusted, the deflection angles of all the motion axis are detected in real time, the real-time deflection angles are compared with the reference deflection angles, and when the real-time deflection angles are consistent with the reference deflection angles, the robot zero calibration is completed. According to the zero calibration method, the position of arobot body at the zero point can be accurately positioned, the error is smaller, and the method is suitable for higher-precision operation of the robot. When the robot is taught by a three-point method, the existing error of a coordinate system during teaching can be known through gestures of different positions displayed, so that the position of the robot can be adjusted conveniently.
Description
technical field [0001] The invention relates to the field of robots, in particular to a robot and a method for zero point calibration thereof. Background technique [0002] At present, when the industrial robot is suddenly powered off and the battery is dead, the zero point may be lost. If the zero mark is set according to the zero mark position on the robot body, the zero position will not be accurate enough. At the same time, if the robot is installed The position is not easy to view the position of the zero mark, which brings difficulties for the robot to zero. Contents of the invention [0003] In view of this, the present invention provides a robot and a zero point calibration method thereof, which can improve the zero point calibration accuracy and facilitate rapid calibration. [0004] Specifically: a method for zero point calibration of a robot, comprising the steps of: [0005] S01: Calibrate the zero position of the robot body; [0006] S02: Detect and record ...
