Problems solved by technology
The self-calibration method uses the redundant sensor calibration of the robot itself, but it cannot provide the unknown rigid body displacement information between the frame reference frame and the calibration measurement reference frame
The external calibration method uses external sensors, such as laser trackers, theodolites, three-coordinate measuring instruments and other precision measurement equipment, but this method is cumbersome to operate, time-consuming to collect data, and difficult to achieve rapid calibration

Embodiment Construction
[0034] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0035] Such as Figure 1 to Figure 3 As shown, in order to achieve the above object, the present invention provides a zero point calibration device for the rotating arm.
[0036] Specifically, the zero point calibration device of the rotating arm includes a limit device and a zero point calibration member 30 arranged on the limit device. The limiting device includes a base 10 and a stop portion 20 protrudingly disposed on the base 10 , wherein the base 10 is marked with a zero point position 11 to determine the precise position of the zero point. The zero point marking part 30 is optionally disposed on the base 10 , one end of the zero point marking part 30 abuts against the stopper 20 , and ...

The invention provides a rocker arm zero calibration device and a robot with the rocker arm zero calibration device. The rocker arm zero calibration device comprises a limiting device and a zero calibration part, wherein the limiting device comprises a base and a stopping portion arranged on the base in a protruding manner, and when carrying out zero calibration, the zero calibration part is arranged on the base. One end of the zero calibration part abuts against the stopping portion, and a zero position is formed at the other end of the zero calibration part. When the zero position is lost and required to be found so as to obtain a benchmark, the zero calibration part is arranged on the base; one end of the zero calibration part abuts against the stopping portion, and the zero position is formed at the other end of the zero calibration part, so that limiting and stopping are acheived on the zero position; and the benchmark point of the zero point an be precisely determined. The rocker arm zero calibration device is simple in structure, easy and rapid in operation, and capable of achieving rapid zero returning and completing zero calibration.
Description
technical field [0001] The invention relates to the field of intelligent machinery, in particular to a zero point calibration device for a rotating arm and a robot having the same. Background technique [0002] The zero point is the datum of the robot coordinate system, without the zero point, the robot cannot judge its own position. In the debugging process of the robot, it is often encountered that the zero point is lost. At present, the self-calibration method and the external calibration method are often used. The self-calibration method utilizes the redundant sensor calibration of the robot itself, but it cannot provide the unknown rigid body displacement information between the frame reference frame and the calibration measurement reference frame. The external calibration method uses external sensors, such as laser trackers, theodolites, three-coordinate measuring instruments and other precision measurement equipment, but this method is cumbersome to operate, time-con...
