20200206934 | METHOD OF CORRECTING POSITION OF ROBOT AND ROBOT - A method of correcting a position of a robot includes: a correction step of rotating an arm around a first axis to detect a rotation angle around the first axis when a target blocks detection light, and locating the first axis, a third axis, and the target on an identical straight line by rotating the arm and/or a hand around the first axis, a second axis, and/or the third axis based on a detection result; and a correction amount arithmetic step of obtaining rotation angle correction amounts of the second axis and the third axis based on the rotation angle of each rotation axis acquired after the correction step in a first posture. | 2020-07-02 |
20200206935 | SERVO CALIBRATION METHOD AND APPARATUS AND ROBOT USING THE SAME - The present disclosure provides a servo calibration method as well as an apparatus and a robot using the same. The method includes: obtaining data of a position sensor on a motor shaft of the servo; obtaining data of a position sensor on an output shaft of the servo; determining whether a clutch protection has been performed on the servo based on data of the position sensor on the motor shaft and data of the position sensor on the output shaft; and calibrating a position of the motor shaft based on the data of the position sensor on the output shaft, if the clutch protection has been performed on the servo. Through the present disclosure, the problem in the prior art that the process of the calibration is cumbersome can be solved. | 2020-07-02 |
20200206936 | SERVO OUTPUT SHAFT ROTATIONAL ANGLE CALIBRATION METHOD AND SYSTEM AND ROBOT USING THE SAME - The present disclosure provides a servo output shaft angle calibration method and a robot using the same. In the method, when a servo output shaft rotational angle calibration instruction is obtained, an output shaft of a servo is controlled to move in a preset rotational direction, a current angle of the output shaft of the servo is obtained when it detects that the output shaft of the servo has rotated to an end point and has a stalling, and then a preset end point angle is updated as the current angle of the output shaft of the servo, so as to take the current angle of the output shaft of the servo as the new end point angle, thereby realizing the calibration of the end point angle of the output shaft of the servo. In this manner, the entire calibration process requires no manual intervention. | 2020-07-02 |
20200206937 | ROBOT SYSTEM AND OPERATING METHOD THEREOF - A robot system includes a robot that self-travels along a traveling shaft and is provided with a position detection sensor at a distal end, a support member that has a plurality of reference positions juxtaposed and supports a workpiece, a plurality of calibration members that are juxtaposed along the traveling shaft, and a control device, in which the calibration members each have a calibration position, and the control device is configured to cause the robot to move by a predetermined first distance along the traveling shaft, calibrate position coordinates of the robot based on position coordinates of the calibration positions detected by the position detection sensor, and subsequently calibrate position coordinates of the workpiece based on position coordinates of the reference positions detected by the position detection sensor. | 2020-07-02 |
