Abstract: 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.

Abstract: A robot cleaner based on wall following and a controlling method thereof are provided. The robot cleaner includes a first detector configured to generate a wall detection signal by detecting a wall, a second detector configured to generate a first contact signal through contact with the wall, a cleaner main body in which the first and second detectors are disposed and which includes a driver configured to drive on a surface to be cleaned, and a controller which is mounted on the cleaner main body and to which the first and second detectors and the driver are electrically coupled.

Abstract: 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.
