Self-adaptive path control method of mobile robot

Abstract

The invention relates to a self-adaptive path control method of a mobile robot. The self-adaptive path control method is characterized by comprising the following steps: at least two road sign locators numbered in sequence are arranged in a working region of the mobile robot; the mobile robot sequentially searches long-distance signals emitted by each road sign locator according to the numbering sequence, and after the signals are searched, the mobile robot moves towards the signals; the mobile robot moves with time and distance as reference, sets a reference point and solves virtual coordinates of the reference point and stores the virtual coordinates as a key point; when receiving the short-distance signals of the road sign locators, the mobile robot solves virtual coordinates of the current position of the mobile robot and stores the virtual coordinates; after sequentially finishing the search of all the road signal locators, the mobile robot corrects the virtual coordinates of thekey point; and the mobile robot cruises according to the corrected virtual coordinates of the key point. The robot system using the method disclosed by the invention has the advantages of strong self-adaptive cruise environment capability, convenience for operation, safety and reliable; in addition, the self-adaptive path control method disclosed by the invention is lower in implementation cost.

Description

technical field [0001] The present invention relates to mobile robots, in particular to the path control of mobile robots. Background technique [0002] With the development of science and technology, robot technology has become more and more mature, and its application fields have become more and more extensive, such as household hygiene, security patrol and so on. [0003] The Rovio developed by WowWee is a mobile cruise camera robot with WiFi control function. Through its built-in camera, users can watch and interact with their environment through real-time video and audio streams. However, when cruising, due to the lack of a specified target and the limited recognition ability of the robot itself, the ability to adapt to the environment is poor, so there is no relatively reliable cruising path. [0004] However, most of the traditional security monitoring systems use the PTZ positioning and rotation method to take pictures. The area to be photographed is limited. If the...

However, when cruising, due to the lack of specified targets and the limited recognition ability of the robot itself, the adaptability to the environment is poor, so there is no relatively reliable cruising path

[0004] Most of the traditional security monitoring systems use the pan-tilt positioning and rotation method to take pictures, and the area of ​​the pictures taken is limited. If it is compensated by the number, the workload and cost of communication, storage, and defense will increase. At the same time, the monitoring system cannot be moved. If you want to If you want to monitor multiple areas, you have to increase the monitoring equipment, which increases the cost
