An embodiment provides a robot including an image photographing unit configured to photograph image information about boarding-scheduled persons located in a gate region differing from a set boarding gate region of a flight-scheduled airplane, an image recognizer configured to perform image processing on the image information to recognize a boarding person matching a facial image of a ticket-issued person of the flight-scheduled airplane among the boarding-scheduled persons, and a controller configured to, when the boarding person is recognized, output movement path information so that the boarding person moves to the boarding gate region.
