Abstract: Disclosed are an apparatus and a method for controlling a camera mounted at a robot cleaner in order to sense obstacles and perform position compensation. The apparatus for controlling a camera of a robot cleaner includes a first axis driver for driving a camera mounted at the robot cleaner in a first axis direction; a second axis driver 320 for driving the camera in a second axis direction other than the first axis direction; an image processor 330 for receiving and processing an image photographed by the camera; and a control section 340 for controlling the first axis driver and the second axis driver, and controlling a traveling of the robot cleaner based on the image photographed by the camera.

Abstract: Disclosed are a moving distance sensing apparatus for a robot cleaner and a method therefor capable of determining a precise moving distance with respect to the robot cleaner by setting a long distance sensor and a short distance sensor having respectively different sensing method from each other on the same sensing line in the robot cleaner to sense the long distance and the short distance for the same direction, and then by determining coherency to each moving distance on the basis of information provided by the two different sensors, the moving distance sensing apparatus comprising: a long distance sensor for sensing a moving distance with respect to a long distance; a short distance sensor mounted on the same sensing line in one-to-one correspondence with the long distance sensor, for sensing a moving distance with respect to a short distance; and a micro computer for determining a moving distance error on the basis of moving distance information with respect to the same direction provided by the long dis

Abstract: Disclosed herein is a mobile robot which is capable of accurately calculating a position of the wireless signal source using a wireless signal, and allowing the mobile robot to accurately and rapidly return to a charging-stand using the calculated position. The position calculation system for a mobile robot includes: a wireless signal source for outputting a wireless signal continuously or periodically; and a mobile robot which includes a plurality of directional antennas for detecting the wireless signal outputted through the wireless signal source, wherein, the mobile robot calculates a direction of the wireless signal source via a rotation angle detected by the directional antennas, and calculates a distance separated from the wireless signal source using a wireless signal detection time difference between the directional antennas.

Abstract: Disclosed herein is a cleaning robot, and more particularly a cleaning robot comprising a camera unit for photographing an external image containing the charging-stand image, converting it into electrical image information, and outputting externally; and a microprocessor for storing the image information inputted the camera unit, acquiring position information of the charging-stand from the external image on the basis of the image information of the charging-stand in detecting a return signal, and causing the cleaning robot to be returned to the charging-stand. The cleaning robot having an auto-return function to a charging-stand detects a direction and position of the charging-stand using image information of the charging-stand, and thereby correctly and rapidly returning to the charging-stand for the cleaning robot.

Abstract: A self-moving robot system, which can specify a moving area using information printed on flooring and move within the area while tracking the printed information, is provided. The self-moving robot system includes a remote controller and a self-moving robot body. The remote controller stores flooring coordinate information wirelessly received from the robot body in a memory, displays the information on a display unit, sets a series of coordinate information elements input by a user as moving area coordinate information, and transmits the moving area coordinate information to the robot body.

Abstract: Disclosed herein is a wireless controllable cleaning robot and remote controlling system for controlling the same, wherein a drive of the cleaning robot is controlled by means of various control signals which are transmitted from a lot of external apparatuses having various wireless communication functions. The cleaning robot includes a wireless communication module and a microprocessor. The wireless communication module receives control signals transmitted from external apparatuses on the basis of various wireless communication protocols. The microprocessor decodes the control signals received through the wireless communication module on the basis of the corresponding wireless communication protocol, and controls a driving of the cleaning robot in response to the decoded operation commands.
