Mobile robot and control method therefor

The present invention relates to a mobile robot and a control method therefor, and, in the event that charging is necessary due to a completely discharged battery, selects areas on the basis of a prestored map and travels in search of a charging base, and is configured such that the mobile robot recognizes the position thereof anew even if the location of the mobile robot is randomly changed, thus easily travels between the areas, is little affected by the complexity of obstacles, and can find the charging base within the areas with a few movements as a result of searching for the charging base by setting a particular spot as a search location within the areas, and thus has the effects of resolving the problem of stopping operating while in search of the charging base, and accurately finding the charging base within a short time.
