Example Embodiment

[0015] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0016] The present application provides a robot navigation method, which can at least be applied to the navigation of indoor robots, such as sweeping robots and working robots. In the robot navigation method provided by this application, after the global path is planned globally, it is no longer necessary to update and adjust the overall planning scheme in real time according to the surrounding environment; instead, it is only necessary when the robot moves abnormally (such as encountering an obstacle, the global path does not allow the robot to pass) etc.) will adjust the overall plan. Through this method, the real-time monitoring of the global environment is omitted, the amount of calculation is greatly reduced, the navigation is more...

Abstract

The present invention discloses a robot navigation method and devices and belongs to the field of robot technologies. The method includes the following steps that: a global path from a starting pointto a target point is obtained through global cost map planning; a robot moves to the target point according to the global path, and performs path tracking during the moving process; whether a movementabnormality occurs during the path tracking is judged; if the movement abnormality occurs, a global cost map is used to re-plan a global path from the current location to the target point. Therefore,with the robot navigation method and devices of the invention adopted, the calculation quantity of the processor of a navigation device can be decreased, and navigation efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of robots, in particular to a robot navigation method, a robot and a storage device. Background technique [0002] Mobile robot navigation is a system and method that realizes that the robot system relies on sensor technology and artificial intelligence technology to move from the starting point to the destination point in a complex environment. Specifically, including environment perception, global planning, local planning, motor control, etc., a large amount of data needs to be processed to realize robot navigation, and in the actual navigation process, the robot needs to continuously detect the surrounding environment information, and update and adjust the navigation according to the specific environment path. In the long-term research and development process, the inventor of the present application found that the real-time processing of these environmental information data resulted in a large ...
