Abstract

The invention relates to the technical field of industrial robots, in particular to a path selecting method and device of a movable robot. The method comprises the following steps: determining a starting point and a target point of the movable robot, wherein the starting point is a center point of the movable robot; judging whether the movable robot can arrive the target point linearly from the starting point or not; if not, selecting a path for the movable robot based on the body of the movable robot. The path selected according to the embodiment further meets the demand of the movable robotwalking, so that the path selecting accuracy is improved, the searched grid number is reduced, and the searching efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of industrial robots, in particular to a method and device for selecting a path of a mobile robot. 【Background technique】 [0002] The A star algorithm is often used in the field of path planning for mobile robots. It is a heuristic search algorithm that greatly improves the search efficiency while ensuring the optimal solution. It is popular today because of its simplicity and ease of implementation. [0003] At present, when planning a path for a mobile robot based on the A star algorithm, the position and size of the mobile robot are usually assumed to be the center of a grid by default, and the path selection for the mobile robot is performed according to the grid according to the determined center. However, in practical applications, mobile robots often occupy several grids. Therefore, in the process of implementing the present invention, the inventor found that the related technology has the followi...
