Embodiment Construction

[0038] A moving chassis distance measurement method during travel includes a single-chassis measurement method and a double-chassis measurement method.

[0039] Such as figure 1 As shown, the single-chassis measurement method includes the following steps:

[0040] A1. Install the positioning unit on the chassis to obtain the coordinate values ​​of the chassis on the Cartesian coordinate axis, and connect the positioning unit and the networking module to the data processing unit;

[0041] A2. Define the static origin and calibration point, place the chassis at the static origin and calibration point to output the coordinates on the corresponding Cartesian coordinate axis through the positioning unit on the chassis, and calibrate the straight line formed by the static origin and calibration point as Y axis;

[0042] A3. After the Y-axis is calibrated, the X-axis is obtained by rotating the positive half-axis of the Y-axis 90° clockwise with the static origin as the center, thu...

Abstract

The invention provides a moving chassis distance measurement method during travel, including a single-chassis measurement method and a double-chassis measurement method. The single-chassis measurement method uses the defined static origin and the calibration point as the Y-axis to establish a plane Cartesian coordinate system, through The distance formula from the point to the straight line calculates the shortest distance between the real-time position of the chassis and the Y axis, that is, the lateral offset distance, and obtains the longitudinal offset distance through the Pythagorean theorem, and completes the measurement of the single chassis; the double-chassis measurement method is through the positioning unit Output the position coordinates of each chassis in the station center coordinate system and the heading angle b between the two chassis to obtain the relative longitudinal distance and relative lateral distance of the chassis, and obtain the lateral offset of the double chassis through the data processing module Distance and longitudinal offset distance, to complete the measurement of the real-time distance offset between the double chassis movement.

Description

technical field [0001] The invention relates to the technical field of robot movement, in particular to a distance measurement method for a moving chassis during travel. Background technique [0002] The motion control of complex robot chassis has been a major problem that has hindered the development of the robot industry, and has not been well resolved for a long time. Even Boston Dynamics, which represents the highest level of robotics, is far from practical. The testing of chassis status and parameters during motion is particularly important for robot motion control, and being able to measure distance in real time during motion control is also a major problem in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a distance measurement method for a moving chassis during travel, which solves the problem that the real-time distance measurement cannot be performed when the chassis is moving. [0004] The present invention ...
