Problems solved by technology

[0005] On the other hand, when the suction part of the cleaning robot is provided in front of the main body, there is a problem that the area close to the wall cannot be sufficiently cleaned during performing wall following (Wall Following) which moves along the wall of the cleaning area.
[0008] However, since there is no configuration disclosed in the above-mentioned prior art documents for solving the problem of not being able to sufficiently clean a portion close to a wall when traveling in a zigzag, there is still a problem that users are not satisfied with the performance of the cleaning robot.

Abstract

In order to realize the method for solving the problem of the present invention, the self-propelled cleaning machine according to an embodiment of the present invention is characterized by comprising: a main body; a driving part for moving the main body; a camera for detecting three-dimensional coordinate information; a memory that stores pattern information related to a charging station; and a control unit that compares the three-dimensional coordinate information detected by the camera with the pattern information related to the charging station stored in the memory, and determines the Whether charging stations are located around the body.

Description

technical field [0001] The present invention relates to a sweeper and a control method thereof, and more particularly, to a sweeper capable of identifying obstacles and performing autonomous travel and a control method thereof. Background technique [0002] Generally, robots have been developed for industrial use and have taken on part of factory automation. Recently, as robots are used in various fields, medical robots, space robots, etc. have been developed, and household robots that can also be used in general households are being developed and manufactured. [0003] A representative example of the home robot is a cleaning robot, a home appliance capable of cleaning by autonomously traveling in a predetermined area and sucking in surrounding dust or foreign matter. Such cleaning robots typically have rechargeable batteries and obstacle sensors that can avoid obstacles during travel, allowing them to clean while driving autonomously. [0004] Recently, in addition to the...
