Abstract

The invention discloses a wheelbase calibration method and system for a robot chassis. The wheelbase calibration method comprises the following steps that a left wheel and a right wheel are driven to rotate, so that a robot rotates circumferentially; the first angle detection device obtains the rotation angle of the robot and records the rotation angle as a first rotation angle, and the second angle detection device obtains the rotation angle of the robot and records the rotation angle as a second rotation angle; correcting the first rotation angle and the second rotation angle to obtain a fusion rotation angle; the speedometer obtains the rotation angle of the robot and records the rotation angle as a third rotation angle; and an initial chassis axle distance of the robot is obtained, and a calibrated chassis axle distance is obtained according to the third rotation angle, the fused rotation angle and the initial chassis axle distance. According to the technical scheme, the speed of calibrating the chassis wheelbase is far higher than that of manual wheelbase calibration, the problem of complexity of manual wheelbase calibration can be effectively solved, and labor productivity is liberated.

Description

technical field [0001] The invention relates to the technical field of wheelbase calibration, in particular to a wheelbase calibration method and system for a robot chassis. 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 and system for ca...
