Robot Map Management System and Robot

Abstract

The invention discloses a robot map management system and a robot, wherein the system includes: a historical map library module, used to acquire and store the map of the environment; a measurement module, used to acquire the measurement signal of the robot to the current environment; map building and positioning A module for establishing the first map of the robot in the current environment and calculating the pose information of the robot in the first map; a matching judgment module for judging whether there is a map matching the first map in the history map library, and outputting the matching Map number; map update module, used to update and / or delete historical maps in the historical map library, and / or add new maps to the historical map library. The system can maintain the validity of the robot's historical map, effectively improve the robustness of the mobile robot's mapping and positioning algorithms, thereby increasing the stability and richness of the map, and can increase more robot intelligent control operations based on the map, improving the user experience. experience.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a robot map management system and a robot. Background technique [0002] At present, the mapping and positioning algorithms of mobile robots often lead to insufficient robustness, so that the robot often re-constructs the map or updates it incrementally. However, after the update, it will become a new map, resulting in The operation of the map also becomes invalid with the change of the map. For example, for a sweeping robot, if the map changes, the unfinished cleaning record of the last time will also be invalidated, and tasks such as intermittent sweeping cannot be performed, which reduces the working efficiency of the sweeper. [0003] In addition, the robot may often work in different environments, or the user has performed a custom operation on the map, which requires management of the map. At the same time, the environment of the mobile robot will also change, ...

Problems solved by technology

[0002] At present, the mapping and positioning algorithms of mobile robots often lead to insufficient robustness, so that the robot often re-constructs the map or updates it incrementally. However, after the update, it will become a new map, resulting in The operation of the map also fails with the change of the map

For example, the sweeping robot, if the map changes, the last unfinished sweeping record will also be invalidated, and tasks such as intermittent sweeping cannot be performed, which reduces the working efficiency of the sweeper

[0003] In addition, the robot may often work in different environments, or the user has performed a custom operation on the map, which requires management of the map. At the same time, the environment of the mobile robot will also change, and the map needs to be constantly updated. However, it needs to be updated on the premise that the historical records can be preserved effectively, and the existing technology needs to be improved
