Abstract: An electric wheelchair according to an embodiment of the present disclosure includes a seat configured to allow a person to be seated, a frame configured to support the seat, a driver configured to be coupled to the frame; and an armrest configured to be hinged to the frame, in which the armrest includes a first portion which extends in a vertical direction and is disposed to overlap a side surface of the frame, a second portion which extends forwardly from an upper-end portion of the first portion, and a third portion which extends forwardly from a lower end portion of the first portion, and when the armrest is rotated from the first position to the second position, at least any one of the first portion and the third portion is disposed to overlap the side surface of the frame.

Abstract: Disclosed herein is a method of controlling a motorized wheelchair, the motorized wheelchair including a seat frame supporting a seat, a back frame to which the seat frame is detachably connected, a first main wheel and a second main wheel respectively installed at both lower ends of the back frame, an inclination detecting sensor which detects an inclination, and a controller which controls the main wheel and the second main wheel, the method includes receiving an input for a turning operation, calculating an inclination angle of a running ground by the inclination detecting sensor, and determining whether the inclination angle is greater than a reference angle.

Abstract: A method of controlling a motorized wheelchair according to an embodiment, the motorized wheelchair including a seat frame provided with a seat for seating of a user, a back frame provided with a backrest for supporting the user's back and detachably connected to the seat frame, and main wheels connected to a lower end of the back frame, may include inputting a reverse command to an input unit, outputting an image photographed by a rear camera installed in the back frame to an output unit, detecting, by a rear height difference sensor installed in bottom of the back frame, a height difference in the ground, determining whether the height difference detected by the rear height difference sensor is larger than or equal to a preset reference height difference, performing an emergency braking defined as activating a brake of the main wheels when the detected height difference is larger than or equal to the reference height difference, and outputting a warning about the detected height difference to the output uni

Abstract: An electric wheelchair according to an embodiment of the present disclosure includes a frame configured to support a seat, a driver configured to be coupled to a lower portion of the frame, armrests configured to be coupled to both sides of the frame, and a controller configured to be detachably coupled to the armrest, in which the controller is coupled so as to shield an opening formed in the armrest and is electrically connected to a connector located inside the armrest. The wheelchair includes a robot.

Abstract: A robot according to an embodiment of the present disclosure may include: a base; a case that is disposed over the base and has an internal space; a front cover that covers the internal space ahead of the case; a projector that is positioned in the internal space, is disposed to face a forward upper side, and projects an image or a video to the front cover; and a built-in component that is disposed ahead of the projector. The front cover may include: a display region in which an image or a video projected from the projector is displayed; and a non-display region that is positioned under the display region and overlaps the built-in component in a front-rear direction.
