Abstract

The application discloses a robot map updating method, which comprises the following steps: step 1, a robot establishes a current map in a current environment; step 2, the current map is updated according to the angle relationship between the current map and a map stored in a historical map library last time, the updated current map is stored in the historical map library, and the updated current map is updated as the map stored in the historical map library last time, so that the current map established in step 1 is updated; wherein each frame of map stored in the same historical map library represents the current environment.
