Disclosed herein are a cleaning robot in which light emitting portions emitting infrared rays are installed to face forward, sideward, and upward and infrared rays which are reflected by obstacles and return are received by one light receiving module to sense obstacles to prevent an increase in manufacturing cost caused by installing a plurality of light receiving portions and simultaneously to sense obstacles located above and a method of controlling the cleaning robot. The cleaning robot including a body and a driving portion which moves the body includes at least one light emitting portion which emits light to an obstacle, a light receiving module which obtains an image signal of the obstacle by receiving the light reflected by the obstacle, and a control portion which generates obstacle sensing information based on a position of the image signal obtained by the light receiving module and controls the driving portion based on the generated obstacle sensing information. Here, the light emitting portion is installed to emit light forward, sideward, and upward from the body and to allow the light reflected by the obstacle to be received by the light receiving module, thereby sensing obstacles located forward, sideward, and above from the body.

Cleaning robot and method of controlling the same

A robot cleaner which does not stop to change a traveling direction thereof, and a control method thereof includes setting a territory about which cleaning will be performed based on position data acquired during traveling about a cleaning area, predetermining a cleaning path to clean the territory about which cleaning will be performed, and if the cleaning path includes a zigzag traveling path, changing the traveling direction of the robot cleaner by executing curved traveling of the robot cleaner during traveling along the zigzag traveling path, thus decreasing the time required to clean an area during a change of the traveling direction of the robot cleaner.
