Abstract
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.
