Robot track positioning method and robot track positioning system

Abstract

The invention provides a robot track positioning method. The method includes the following steps: (1) a robot track positioning system is provided, a robot, at least one track with gaps, a sensing device arranged on the robot and a mileage device arranged on the robot are further included, and the robot can reach a given location through the track; (2) spaces between positioning gaps of the track are arranged symmetrically and unequal spaces between any two gaps are guaranteed; and (3) the sensing device is used for reading positioning gap information on the track, wherein the robot is on the track, and mileage information of the mileage device and space information of positioning gaps are used for acquiring a current location information of the robot, wherein the space information is preset. The robot track positioning method aims at using a manner which is high in accuracy and reliable to finish positioning of the robot in a horizontal position. Compared with positioning manners such as laser, vision, infrared, ultrasound and global position system (GPS), the robot track positioning method is more suitable for applying to the environment which has higher requirements for reliability such as a factory and a converting station.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a method and system for positioning a robot track with relatively high accuracy. Background technique [0002] A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Its task is to assist or replace human work, such as production, construction, or dangerous work. At present, robots are developing rapidly and have been applied in many industries. [0003] Robot positioning is a very important technical point in the process of robot walking. In the patent application with the application number 200710168718.1, a robot autonomous positioning system is disclosed, which belongs to the robot intelligent control device and solves the problem of high-precision autonomous positioning of the robot in the underground environment. The patent includ...

AI Technical Summary

Problems solved by technology

[0004] This kind of robot is mainly used in the underground environment, so its underground environment and other factors must be considered when considering positioning, so the implementation is more complicated

[0005] Existing robot positioning mainly includes infrared positioning, laser ranging positioning, GPS positioning, ultrasonic positioning, RFID positioning, etc., among which simple infrared positioning and laser ranging positioning are greatly affected by the intensity of infrared light in the environment, and when environmental information changes (such as obstacles on the workplace) may easily cause positioning errors, and is easily affected by dust and particles in the environment; the accuracy of ultrasonic positioning and RFID positioning is low; GPS positioning is not suitable for indoors such as factories

Therefore, it is difficult for the existing positioning systems to simultaneously ensure the accuracy of positioning and ensure the reliability in a dusty indoor environment.
