Abstract: A robot cleaner is provided. The robot cleaner may precisely detect a peripheral obstacle using a particular optical pattern. An asymmetric cross-shaped optical pattern may be irradiated, and a pattern image with respect to the optical pattern-irradiated region may be analyzed to determine whether or not an obstacle is in the moving path, and a width or a height of the obstacle. Further, the robot cleaner may perform operations such as a forward motion, a backward motion, a stopping motion and a detour motion, based the obstacle detection result.
