Moving robot and operating method

Abstract

The invention relates to a moving robot and an operating method thereof. Data within a designated distance from a main body of the mobile robot is accumulated and stored to form a local area map. A traveling direction or a rotating direction is set while avoiding an obstacle around the main body and a path may be readily set. Repetition of unnecessary operation is prevented and thus a traveling velocity based on rapid movement may be improved. Obstacles are readily avoided and cleaning efficiency may be improved.

Description

[0001] related application [0002] This application claims priority from Korean Patent Application No. 10-2013-0131621 filed with the Korean Patent Office on Oct. 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 which generates a map (Map) around the mobile robot and walks based on the stored map and its working method. Background technique [0004] A mobile robot is a device that automatically cleans by sucking in foreign matter such as dust from the ground while walking on its own in the area to be cleaned. [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 stand to charge the battery when necessary. [0006] Usually, such a mobile robot detects the distance to obstacles such as furniture, office supplies, a...

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.
