First Claim
Patent Images
1. A moving robot, comprising:
- a photographing unit for photographing an image using incident light;
at least one light source unit for radiating light onto a region photographed by the photographing unit; and
a controller for controlling the light source unit when errors are generated in data input from the photographing unit.

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.

8. A moving robot, comprising:
-
a photographing unit for photographing an image; at least one light source unit for radiating light so that the photographing unit can photograph an image; a light source controller connected to the light source unit to control a light amount or a light radiation angle of the light source; a light amount sensing unit for sensing the amount of light radiated from the light source unit; and a controller for comparing data input from the photographing unit at predetermined time intervals to operate a moving distance and for controlling the light source unit through the light source controller when errors are generated in the data input from the photographing unit or when it is determined by the light amount sensing unit that the light amount of the light source unit is insufficient or excessive. - View Dependent Claims (9, 10, 11)
