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 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.

Abstract: A mobile terminal and a method for controlling the same are disclosed. The mobile terminal includes: a display configured to output a specific image in the image view mode; an extractor that extracts a specific area from the specific image, based on a touch gesture on the specific image; and a controller that creates a thumbnail of the specific image from an image of the extracted specific area, and when the image preview function is executed, outputs a thumbnail list that displays the created thumbnail of the specific image to be visually distinct from the thumbnails of other images.
