Problems solved by technology
In this case, the number of executions specified by the manufacturer of the robotic cleaner is often less than necessary for the size of the room, resulting in unsatisfactory cleaning of the room and areas that were not cleaned
Otherwise, if the number of executions specified by the manufacturer greatly exceeds the appropriate number of executions, there will be no areas that are not cleaned, but the number of areas that are repeatedly cleaned will increase, resulting in an inevitable decrease in the battery life of the robot cleaner
[0007] In addition, if the area being cleaned is complex, there will also be areas that are not cleaned
Specifically, if the robot cleaner rotates on the corner portion adjacent to the wall, it is difficult for the conventional robot cleaner to effectively clean the corner portion

A robot cleaner and a method of controlling the same are disclosed. The robot cleaner cleans a given cleaning area simultaneously while moving in the cleaning area. The method includes detecting whether an obstacle exists in a traveling path of the robot cleaner, determining whether the detected obstacle is an edge when the obstacle is detected, cleaning a predetermined area centering around the edge when the detected obstacle is determined to be the edge, and determining whether the cleaning area is completely cleaned on the basis of information of the detected edge while cleaning the predetermined area.
Description
technical field [0001] The present invention relates to a robot cleaner that moves in a specific area to be cleaned by the robot cleaner to clean the specific area, and more particularly, relates to a method of using edge information of a target area to determine a target area. A robot cleaner indicating whether an area is completely cleaned and a method for controlling the robot cleaner. Background technique [0002] Generally, the robot cleaner moves in a target area to be cleaned by the robot cleaner without receiving a user's command, and absorbs dust or impurities from the ground of the target area, thereby cleaning the target area. The robot cleaner uses its sensors to determine its distance to obstacles (such as furniture, office supplies, or walls) contained in the target area, and based on the determined distance, moves in the target area without colliding with the obstacles, thereby cleaning target area. [0003] The above case of cleanin...
