A remote control method for a robot, comprising: receiving an ambient image (410, 610, 810, 810', 920, 920') of surroundings of a robot from a camera provided at the robot; outputting a map image (420, 620, 820, 820', 910, 910') including location information corresponding to the ambient image (410, 610, 810, 810', 920, 920') to a display unit together with the ambient image (410, 610, 810, 810', 920, 920'), wherein a display area of the display unit includes a main area and a sub-area, wherein one of the ambient image (410, 610, 810, 810', 920, 920') and the map image (420, 620, 820, 820', 910, 910') is output to the main area, and the other is output to the sub-area, wherein a size of the main area is larger than that of the sub-area; generating a control command for controlling navigation of the robot in response to a user input to the display unit in a state that the ambient image (410, 610, 810, 810', 920, 920') and the map image (420, 620, 820, 820', 910, 910') are being output to the display unit; and transmitting the control command to the robot such that the robot drives according to the control command; characterized in that when the user input is applied to the sub-area, control of the display area is performed such that visual information being output to the main area and the sub-area, respectively, is switched from each other, in addition to the generating of the control command for controlling the navigation of the robot, and when the user input is applied to the main area, the generating of the control command for controlling the navigation of the robot is performed without said switching of visual information. receiving an ambient image (410, 610, 810, 810', 920, 920') of surroundings of a robot from a camera provided at the robot; outputting a map image (420, 620, 820, 820', 910, 910') including location information corresponding to the ambient image (410, 610, 810, 810', 920, 920') to a display unit together with the ambient image (410, 610, 810, 810', 920, 920'), wherein a display area of the display unit includes a main area and a sub-area, wherein one of the ambient image (410, 610, 810, 810', 920, 920') and the map image (420, 620, 820, 820', 910, 910') is output to the main area, and the other is output to the sub-area, wherein a size of the main area is larger than that of the sub-area; generating a control command for controlling navigation of the robot in response to a user input to the display unit in a state that the ambient image (410, 610, 810, 810', 920, 920') and the map image (420, 620, 820, 820', 910, 910') are being output to the display unit; and transmitting the control command to the robot such that the robot drives according to the control command; characterized in that when the user input is applied to the sub-area, control of the display area is performed such that visual information being output to the main area and the sub-area, respectively, is switched from each other, in addition to the generating of the control command for controlling the navigation of the robot, and when the user input is applied to the main area, the generating of the control command for controlling the navigation of the robot is performed without said switching of visual information.
