Claim 12:
13. A method for traveling in a corner area, performed by a moving robot comprising a main body, a driving unit configured to move the main body, a sensing unit configured to emit sensing light for detecting whether or not an obstacle exists at a front of the main body so as to generate an emission result, and a control unit configured to detect whether or not an obstacle exists in a traveling environment of the main body based on the emission result of the sensing unit, so as to control the traveling of the main body according to a result of the detection, the method comprising:
generating image information by accumulating the emission results for the corner area;
generating identification information by extracting an area corresponding to a predesignated reference area from the image information;
detecting whether or not an obstacle exists in the corner area based on a result of comparing the identification information with pre-stored reference information; and
traveling in the corner area in response to a result of the detection,
wherein the sensing unit comprises a three-dimensional (3D) camera sensor to emit the sensing light to the front of the main body,
wherein the three-dimensional camera sensor is provided to face the ground in front of the main body to emit the sensing light onto the ground in a form of line beam,
wherein the generating the image information is configured to generate the image information by accumulating the emission results of the sensing unit according to a predetermined criterion,
wherein the predetermined criterion is a criterion of the image information for identifying information on the corner area, and
wherein the predetermined criterion is a criterion for a volume of the image information, an emission time of the sensing unit, or an amount of data required for the emission result.
