Abstract

The invention aims to provide a path search method and device for a mobile robot. According to the invention, a high-level strategy of efficiency path searching is carried out on a large map by usinga rapidly-exploring random tree (RRT), users can create an RRT during map establishment or create an RRT for a large known map in real time, then the created RRT is applied to a subsequent path searchalgorithm so as to enable the search time to be greatly reduced. The path search method and device can quickly search a path between a set starting point and an end point and provide the path to an upper navigation system of the robot to use. The core advantage of the RRT is that the time is extremely short, thereby being applicable to the use in embedded equipment, and solving the defect of longconsumed time of the traditional path search algorithm.

Description

technical field [0001] The invention relates to the field of computers, in particular to a path search method and equipment for a mobile robot. Background technique [0002] With the improvement of people's living standards, various home service mobile robots have sprung up in recent years, such as sweepers, automatic food delivery robots, bank teller robots and so on. At present, while improving basic functions, service robots have added more mobile chassis technology, enabling products to move autonomously and perform map construction and navigation. Traditional mobile robots use the shortest path algorithm (Dijkstra), which has the advantage of being able to find the optimal path, but has disadvantages such as time-consuming and frequent search failures, and is not suitable for commercial environments and large family environments. Contents of the invention [0003] An object of the present invention is to provide a path search method and device for a mobile robot. ...
