Disclosed is a mobile robot and a controlling method of the same. An entire movement region is divided into a plurality of regions, and a partial map is gradually made by using feature points of a plurality of images of the divided regions. Then, the map is compensated into a closed curved line, thereby making an entire map. Furthermore, when the mobile robot is positioned at a boundary of neighboring regions of the cleaning region, the boundary where a closed curved line is formed, the mobile robot compensates for its position based on a matching result between feature points included in the map, and feature points extracted from images captured during a cleaning process.

Mobile robot and controlling method of the same

There are provided a moving robot and a method of operating the same. A bottom surface is photographed to sense a moving distance and a moving direction based on input image data. The amount of light radiated to photograph the bottom surface is sensed to feedback control the light emission degree of a light source unit. The light source unit is controlled when errors are generated in sensing the image data. Therefore, the sensing ratio of the photographed image is improved so that correctness of calculating the position of the moving robot is improved.
