Indoor robot system based on visible light positioning and navigation

Abstract

The invention discloses an indoor robot system based on visible light positioning and navigation. The indoor robot system comprises a visible light positioning and emitting unit used for sending positioning information, a visible light positioning and receiving unit used for receiving a visible light signal to perform positioning and navigation, a drive unit for driving a robot to move, a mechanical structure unit used for moving the robot, a sensing unit used for monitoring an external environment, a computer visual unit used for obtaining image information, a robot micro type computer unit, a control display panel unit and a power supply, wherein the robot micro computer unit is used for firstly obtaining values of all sensors of the sensing unit, controlling the robot system to avoid obstacles during walking motion, obtaining and processing images acquired by the computer visual unit, and helping the robot system to predicate and avoid pedestrians better; and in a moving process, the visible light signal with coding information is extracted to perform positioning and navigation after a visible light image receiver performs quick image obtaining on an indoor visible light signal light source.

Description

technical field [0001] The invention relates to the research field of robots, in particular to an indoor robot system based on visible light positioning and navigation. Background technique [0002] In recent years, global sales of industrial robots have increased significantly. At the same time, service robots are developing rapidly and their application scope is becoming wider and wider. The Ministry of Industry and Information Technology, the Development and Reform Commission, and the Ministry of Finance jointly issued the "Robot Industry Development Plan (2016-2020)" on March 21, 2016, emphasizing the vigorous development of the robot industry. [0003] Intelligent robots for indoor applications are one of the important development directions. But the biggest problem that indoor robots are currently facing is the problem of positioning and navigation. If robotic technology is represented by a pyramid, then positioning and navigation, as the bottom-level technology, is...

AI Technical Summary

Problems solved by technology

Among the common positioning and navigation methods, electromagnetic navigation is simple and relatively mature, although the cost is low, but it is troublesome to lay; using WiFi, Bluetooth, UWB, etc. for positioning, the signal is easy to attenuate and the accuracy is poor; using vision for navigation, long-distance high-pixel processing , the speed will be slower, and the real-time performance is not good
