Abstract: A robot and a controlling method thereof are provided. The robot includes: a driver; first and second communication interfaces; a memory storing instructions; and a processors configured to execute the instructions and cause the robot to: based on receiving an instruction to move to a second floor from a first floor, control the robot to board an elevator, based on identifying that the elevator is stopped, obtain through the first communication interface Wi-Fi device identification information, identify whether a floor on which the elevator is stopped is the second floor based on the Wi-Fi device identification information, based on identifying that the elevator is stopped on the second floor, identify whether the elevator door is open based on a RSSI value of a signal received through the second communication interface, and based on identifying that the elevator door is open, control the robot to get off the elevator.

Abstract: A robot apparatus is disclosed. The robot apparatus includes a main body; a display; a neck structure rotatably connected to the main body; a first driving device configured to rotate the neck structure such that the display is positioned in a first location, in which a display surface of the display faces toward an upper direction, or a second location, in which the display surface faces toward a front direction; a stopper structure provided on the main body to be adjacent to the neck structure; and a second driving device configured to move the stopper structure toward the front direction or a rear direction such that the stopper structure is positioned in a supporting location in which the stopper structure contacts a rear surface of the neck structure, or a separated location, in which the stopper structure is spaced apart from the neck structure.
