Abstract: A mobile robot may include a plurality of position information transmitters installed in an area to transmit signals for determining position information, a terminal configured to analyze the signals received from the position information transmitters and a mobile robot configured to receive the signals from the position information transmitters to determine the position information, and to set a boundary in the area based on the position information, wherein the terminal evaluates an installation position of the position information transmitters by analyzing the signals received from the position information transmitters. Accordingly, even when a work area is reduced or enlarged, a position information transmitter may be further provided, such that a boundary may be reset easily for an enlarged area. And by evaluating an installation position for the position information transmitter in an area, a position that facilitates signal transmission and reception may be determined for installation, thereby preventing a problem that an obstacle interrupts signal reception, and position information may be confirmed easily, thereby improving accuracy of positions.

Abstract: A moving robot has a body and at least one wheel for moving the main body. The moving robot has a transceiver to communicate with a plurality of location information transmitters located within an area. The moving robot also has a memory storing coordinate information regarding positions of the location information transmitters. Further, the moving robot has a controller that sets a virtual boundary based on location information determined using signals transmitted by the location information transmitters. The controller controls the wheel so that the main body is prevented from traveling outside the virtual boundary. The controller sets a reference location information transmitter and corrects the stored coordinate information by correcting height errors based on height differences between the reference location information transmitter and the other location information transmitters. The controller also corrects a current position of the main body based on the corrected stored coordinate information.

Abstract: A moving robot and a controlling method thereof are disclosed. A moving robot according to the present disclosure includes a traveling unit to move a main body, a communication unit to communicate with a location information transmitter for transmitting signals within an area, and a control unit to set a virtual boundary with respect to a location calculated based the signals, and to control the traveling unit to move the main body without departing from the boundary. The communication unit includes first and antennas provided at respective transceivers that transceive signals with the location information transmitter, and the first and second antennas have an adjustable distance. When signals are received through the first and second antennas, the control unit determines a relative location of the location information transmitter based on a current location of the main body using a frequency corresponding to the distance between the first and second antennas.

Abstract: A mobile robot may include a controller configured to set a virtual boundary based on position information determined by a terminal or a position sensor in an area, and to set an area of any one side of the boundary as a traveling area. The controller may control a traveling unit so that a main body moves within the traveling area without moving outside the boundary. Accordingly, the controller may easily set the boundary using the position information, and may control traveling of the mobile robot by setting the traveling area formed by the boundary. The controller may correct a position error, may reflect information on obstacles in setting the traveling area to set a traveling area appropriate for a traveling environment of the mobile robot, and/or may easily change the set traveling area.
