A method of controlling a 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, 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.

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.

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 unit.

Load control apparatuses, systems and methods to control a location, orientation, or rotation of a suspended load by imparting thrust vectors to the suspended load or to a structure that holds the load. The load control apparatuses, systems and method may be integrated into a structure that holds a load, such as a rescue litter. The load control apparatuses, systems, and methods may be modular. The modular load control apparatuses, systems, and methods may be secured to a load or to a structure that holds the load.

A single-seat electric-vehicle travel control apparatus controls traveling of a single-seat electric vehicle by using output of a user-input detection device which has an input scheme different from those of conventionally proposed input apparatuses and which is highly versatile. A first user-input information acquisition unit acquires first user-input information, which indicates a first user action detected by the first user-input detection device. A second user-input information acquisition unit acquires second user-input information, which indicates a second user action detected by the second user-input detection device without contact with the second part of the user's body. A multi-input controller determines a first user intention based on first user-input information acquired by a first user-input information acquisition unit. The multi-input controller determines a second user intention based on second user-input information indicative of a second user action. The multi-input controller generates a control signal for controlling traveling means based on the first user intention and the second user intention.

The invention relates to an adaptive attachment wheel for wheelchairs, formed as a unit consisting of: a wheel (5); frame segments (1); adaptation shells (7, 8) for lateral guidance on the wheelchair front tubes; and at least one holding element (6) that can be fastened to the wheelchair; such that, when the adaptive attachment wheel is attached to the wheel-chair, the adaptation shells (7, 8) are brought together with the wheelchair front tubes, the front casters of which are lifted off of the ground, and a three-wheeled wheelchair is produced, the front wheel (5) of which can be steered and braked by means of an one-hand steering system (13).

A seat, a motion control method thereof and a motion control system thereof. The motion control method for the seat includes: acquiring images of around the seat, and tracking a current caregiver via image recognition; determining a relative position between the current caregiver and the seat; and controlling a motion of the seat based on the relative position.

A wheelchair comprises a chair frame, two armrest support rods, two armrests, a plurality of wheels, and at least one pedal mechanism. The two armrest support rods connect the chair frame in a telescopic manner, and located at two sides of the chair frame, respectively. The two armrests connect the two armrest support rods, respectively, and can be moved forward and backward relative to the connected armrest support rods in a horizontal direction. The plurality of wheels connects a base portion of the chair frame. The at least one pedal mechanism includes a connecting rod and a foot pedal. The connecting rod is pivotally mounted at a front side of the chair frame, and the foot pedal is pivotally connected to the connecting rod, so that the connecting rod may drive the foot pedal to pivot about the pivotally connected end. Similarly, the foot pedal can also pivot relative to the connecting rod. Through the above design, the wheelchair can be adjusted according to the user's physique and requirement.

A mobile wheelchair/chair, especially for the disabled, having a body support system mounted on the casing, a swivel and drive assembly and castors is characterized in that the swivel and drive assembly equipped with drive motor (8) and swivel motor (5) has s form of coupled vertical fixed fork (6) furnished with at least one swivel wheel (7), and seat (3) is mounted on the steering and swivel axis of fixed fork (6), with swivel motor (5) located in the upper part of the steering and swivel column (6a) of fixed fork (6). Casing (1) is equipped with castors (2) in its lower part.
