MOBILE ROBOT AND CONTROLLING METHOD OF THE SAME
First Claim
1. A mobile robot comprising:
- an image detection unit configured to detect image information by capturing images of surroundings;
a storage unit configured to store the image information; and
a controller configured to recognize an absolute position by comparing currently detected image information with stored image information, and detect a position of a charging station based on the recognition result of the absolute position.

Abstract
In a mobile robot and a controlling method of the same, the mobile robot is able to recognize a precise position thereof by detecting a plurality of images through an image detection unit, extracting one or more feature points from the plurality of images, and comparing and matching information related to the feature points. The mobile robot is also able to easily detect a position of a charging station based on image information, and quickly move to the charging station upon the lack of residual battery capacity. The mobile robot is also able to detect a position of the charging station based on the image information and receive a guideline signal within a signal reception range, so as to easily dock with the charging station.
