Problems solved by technology

[0008] However, in the case of using such a sensor, although it is possible to ensure a certain degree of accuracy in detecting whether there is an obstacle on the walking path, it is difficult to detect the distance to an obstacle or detect the ground in a cleaning area such as a steep slope. There is a problem that reliable accuracy cannot be ensured in terms of conditions and other aspects, and this kind of distance recognition causes errors.
[0009] In addition, even if the mobile robot walks after forming a map, there is a problem that it cannot cope with sudden route changes because it does not store data related to the route it has passed.

Abstract

The present invention relates to a mobile robot and its working method, which accumulates and stores the detected data, and stores the data within a specified distance from the mobile robot centered on the mobile robot to generate a surrounding map, thereby avoiding obstacles around the main body while avoiding obstacles around the main body. By setting the direction of travel or rotation, the path can be set quickly, preventing repeated unnecessary work, thereby increasing the travel speed with fast and rapid movement, and moving in a way that is easy to avoid obstacles, so it has cleaning efficiency Get an improved effect.

Description

[0001] Related applications [0002] This application claims priority to Korean Patent Application No. 10-2013-0131621, filed with the Korean Patent Office on October 31, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a mobile robot and its working method, in particular to a mobile robot and its working method that generate a map (Map) around the mobile robot and walk based on the stored map. Background technique [0004] A mobile robot is a device that automatically cleans while walking on the area to be cleaned while sucking in dust and other foreign objects from the ground. [0005] The mobile robot has a rechargeable battery, can move freely, and can use the working power of the battery to move by itself, and return to the charging base to charge the battery if necessary. [0006] Generally, such a mobile robot detects the distance from obstacles such as furniture, office supplies, and w...
