Abstract: A mobile robot for determining whether to board an elevator may include a camera configured for capturing an inside of the elevator, an object recognition unit configured for recognizing an area of the elevator and the number of passengers from an image captured by the camera, and a control unit configured for calculating a density of the elevator based on the area and the number of passengers. The control unit may perform a determination of whether to board the elevator based on the density, and control a driving wheel motor based on the determination.

Abstract: A mobile robot driving wheel deforming device is capable of changing a wheel base and a mobile robot comprising same. To this end, provided is a mobile robot (100) driving wheel deforming device comprising: a first driving wheel (200) for driving the mobile robot (100); a third arm (152) connected to the first driving wheel (200); a second driving wheel (210) for driving the mobile robot (100); a fourth arm (154), one end of which is connected to the second driving wheel (210), and the other end of which is connected to the third arm (152) such that same rotates integrally; a third driving wheel (220) for driving the mobile robot (100); a second arm (114), one end of which is connected to the third driving wheel (220); a second shaft (150) installed in an area in which the third arm (152) and the fourth arm (154) are connected, thereby rotating the third arm (152) and the fourth arm (154); and a second-shaft servomotor (330) for rotating the second shaft (150).

Abstract: An omni-wheel device is capable of driving on both flat and stepped terrains. The omni-wheel device may include an omni-wheel segment of which an area in contact with the ground includes a portion of an omni-wheel, an actuator capable of moving the omni-wheel segment in the radial direction, and a wheel drum to which one end of the actuator is fixed and in which a rotation shaft is assembled at the center thereof.
