Disclosed is a drive unit for a wheelchair and a wheelchair including such. The wheelchair includes a control input and a structural frame with two lateral frame elements, each supporting a drive wheel. The drive unit includes two drive motors within a driveshaft housing, adapted to drive the drive wheels independently based on input via the control input. The drive shaft housing is releasably attached between the two lateral frame elements of the wheelchair and connected to the drive wheels via quick-release couplings. The drive shaft housing is divided into at least two sections, each section housing one of the drive motors and that the at least two sections of the drive shaft housing are telescopically moveable relative to each other for adjusting the width of the drive shaft housing to different wheelchairs having different distances between the lateral frame elements of the structural frame of the wheelchair.

A hand propelled wheeled vehicle, specifically a wheelchair, containing a pair of hand actuated, lever driven mechanisms to rotate the main wheels. The levers pivot around attachment points on the left and right sides of the vehicle chassis. The left lever actuates a frame responsible for contra-rotating two integral one-way clutches arranged on a drive shaft coupled to the left main wheel, with the right lever operating the right side mechanism in an identical fashion. The arrangements of the clutches utilize both the forward (pushing) and backward (pulling) stroke of the lever to rotate the main wheels forward. Steering and braking control is afforded through attachments integral to the hand grips of the right and left hand levers, respectively.

A motorized armchair for the movement of a person with motor impairments includes an adjustable motorized armchair structure having a resting base, a seat and a back oriented with respect to each other and/or moved integrally with respect to each other relative to the ground. The armchair includes at least one mechanical movement system, provided with at least one actuator and kinematic transmission elements to move and/or orient the seat and back.

The armchair includes a support and movement structure to be fixed to the armchair structure between the resting base and ground having a supporting frame to which at least two driving wheels actuated by at least one motor and two steerable wheels fixed to allow movement of the armchair along the ground. The armchair includes a control interface connected to the motor and actuator to actuate movements of the seat and back and movement of the motorized armchair.

Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.

A personal mobility device may provide mobility assistance to a user, such a user having a disability or impairment. The personal mobility device may comprise autonomous or semi-autonomous functions permitting navigation and maneuvering within complex and dynamic environments. The personal mobility device may be operable to maneuver within an interior or exterior environment. The personal mobility device may utilize navigational data for autonomous or semi-autonomous functions.

The invention relates to a mobility scooter for individual mobility of a person, comprising a chassis, two front wheels aside the chassis and at least one rear wheel, a seat with a seat base and armrests for the person, a footrest on the chassis that extends between the seat and the front wheels, and an electronic controller assembly, wherein the mobility scooter has a driving mode and a boarding mode, wherein in the driving mode the seat base and the armrests are in the driving position, and wherein in the boarding mode the seat base or at least one of the armrests is in the boarding position, wherein the electronic controller is configured to steer the front wheels in the boarding mode into the sideward steering direction that is opposite to the side to which the seat base or the armrest is swung in the boarding position.

A wheeled personal mobility device for transporting a person, an electric motor for use with the personal mobility device, a splined connection, an electromagnetic braking system and a steering engagement mechanism. The wheeled personal mobility device may be embodied as a wheeled personal mobility aid. The wheeled personal mobility device is reconfigurable between at least three configurations.

The present disclosure discloses a method and system for controlling mechanical transmission of an intelligent wheelchair. The system may include a processor, a motion module, and a tripod head. The processor may be configured to perform operations of receiving information, constructing a map, planning a route, and generating a control parameter. The motion module may execute the control parameter to move around and may include a sensor to sense information. The tripod head may include a sensor to sense the information.

Disclosed is a driving method of 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.

An electric vehicle includes a first instructor operated by a first operator; a second instructor operated by a second operator; a third instructor performing an instruction of deceleration or stop by determining a possibility of collision; a controller for selecting one of instructions from the first instructor, the second instructor, and the third instructor; and a driver driving according to the instruction from the controller, in which in a case of receiving the instructions from at least the first instructor and the third instructor, the controller preferentially selects the instruction from the third instructor to the instruction from the first instructor.
