Disclosed is a wheelchair power apparatus for electronic driving conversion. It is an object of the present invention to provide a wheelchair power apparatus for electronic driving conversion, which can provide severely disabled people, for instance, patients with spinal cord injury, the weak or the old, who use wheelchairs, with convenience in movement, and convert a manual four-wheel wheelchair into an electronic three-wheel wheelchair just by detachably mounting the electronic module having electronic wheels to the existing manual four-wheel wheelchair.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A sub-mobility device charging system for a vehicle is capable of moving while carrying a sub-mobility device in which a passenger sits. The system includes an acquisition unit, a main electric power supply unit and a controller. The acquisition unit acquires a destination or traveling schedule inputted to the sub-mobility device; the main electric power supply unit supplies electric power to the sub-mobility device carried in the vehicle; and the controller controls to supply electric power to the sub-mobility device via the main electric power supply unit. The controller charges the sub-mobility device on a basis of the acquired traveling schedule for the sub-mobility device in the destination, and generates a traveling route to guide the charged sub-mobility device to a stop-off points corresponding to the destination.

A moving device includes: two leg portions each including an end-portion wheel and an intermediate wheel; a placement portion supported by the two leg portions; and a control unit configured to control the two leg portions. The moving device is configured such that, under a state of four-wheel ground contact in which the end-portion wheel and the intermediate wheel are in contact with the ground, when the end-portion wheel is moved from the boarding area to the step of the escalator and/or when the end-portion wheel is moved from the step to the landing area of the escalator, a wheel speed of the end-portion wheel is controlled by the control unit.

A patient treatment system includes one or more automated patient transporters configured to move a patient from a preparation area to one of a plurality of alternative treatment areas, and to position the patient relative to a therapeutic radiation beam. Both transportation of the patient and positioning of the patient are optionally performed while the patient is secured to one of the patient transporters. A control system may be used to both position and transport the patient responsive to a patient treatment plan.

Disclosed is a Wheelchair Electric Mobility Attachment including a rear wheels chassis functionally connected to a front chassis fork, for positioning two or more rear wheels of the mobility attachment, as part of a wheelchair connection scheme, at a position behind (further back from) the axle of the rear wheels of the wheelchair to which said attachment is being connected.

A seated vehicle comprises a frame, one or more first wheels at a first position relative to the frame, one or more second wheels at a second position relative to the frame, and a wheel-positioning system. The wheel-positioning system includes one or more arms pivotally coupled to the frame, and an adjustment mechanism operatively coupled to a first position of the one or more arms. The one or more first wheels are operatively coupled to a second position of the one or more arms. The adjustment mechanism moves the one or more arms between a first position and a second position so that the one or more first wheels are in a first position relative to the one or more second wheels when the one or more arms are in the first position and are in a second position relative to the one or more second wheels when the one or more arms are in the second position.

The present invention relates to an electric wheelchair having a voice recognition drive system comprising: a traveling apparatus main body unit which has a plurality of wheels in a lower end thereof; a seating unit which is installed in an upper end of the traveling apparatus main body unit so as to be able to be lifted; an auxiliary robot leg unit which is able to be inserted into and protrude from the traveling apparatus main body unit, and which includes multi-joint driven by an external force; and a voice recognition drive unit which extracts a preset command from an externally input voice, and which drives the plurality of wheels, lifts the seating unit, and drives the auxiliary robot leg unit.

Disclosed is a mecanum wheel, including a mecanum wheel body and a drive device. A wheel axle hole is formed in the mecanum wheel body. The drive device is partially or completely arranged in the wheel axle hole. The axis of a connecting shaft of the drive device is collinear with a rotary shaft of the mecanum wheel body, and the mecanum wheel body rotates along with a housing of the drive device. Further disclosed are a mecanum wheel with a shock absorbing device, a chassis including at least one pair of mecanum wheels, and an assistant robot including a chassis.
