Embodiment Construction

[0041] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0042] see image 3 The left wheel 1 of the robot is located on the left side of the robot chassis, and the right wheel 3 of the robot is located on the right side of the robot chassis. The left wheel and the right wheel can drive the robot to rotate left or right on the bearing surface. The rotation axis of the robot is perpendicular to the carrying surface, which may be the ground. Also be provided with at least one auxiliary wheel 5 (can be universal wheel) on the robot chassis, be used for the traveling of auxiliary robot. The wheelbase of the robot chassis refers to the distance between the left wheel 1 and the right wheel 3, and the error of the wheelbase will cause the error of the angular velocity (rotation angle) fed back by...

Abstract

The invention discloses a robot chassis wheelbase calibration method and system. The calibration method comprises the following steps that a left wheel or a right wheel is driven to rotate so as to drive a robot to rotate; the moving distance of the left wheel or the right wheel is obtained, and the rotating angle of the robot is obtained; and according to the moving distance of the left wheel or the right wheel and the rotating angle of the robot, the calibrated chassis wheelbase is calculated. According to the technical scheme, the robot can obtain the calibrated chassis wheelbase of the robot according to the moving distances of the left wheel and the right wheel and the rotating angle of the robot, and the inaccurate wheelbase of the robot is replaced, so that the accurate wheelbase is obtained in real time, and the advancing stability of the robot is improved. Moreover, the speed of calibrating the chassis wheelbase is far higher than the speed of manual wheelbase calibration, the complexity of manual wheelbase calibration can be effectively solved, and the labor productivity is liberated.

Description

technical field [0001] The invention relates to the technical field of wheelbase calibration, in particular to a method and system for calibration of a robot chassis wheelbase. Background technique [0002] The error produced by the robot production process will correspondingly lead to the error of the wheelbase of the robot chassis. The error of the wheelbase will cause the error of the angular velocity (rotation angle) of the robot wheel feedback. The error of the wheelbase will also affect the position of the center of gravity of the robot, and then affect the robot. Stability of travel; thus the robot's travel ability is affected. [0003] The wheelbase of the existing robot chassis is calibrated by means of a standard measuring instrument (such as a vernier caliper), and then the calibrated wheelbase value is input to the robot. This calibration method is too inefficient. Contents of the invention [0004] Therefore, it is necessary to provide a method for calibratin...
