A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

The lateral movement wheelchair is a device adapted for use with wheelchairs. The lateral movement wheelchair is a spring loaded device that is attached to the tipping levers of a wheelchair. When the lateral movement wheelchair is lowered to the ground, the wheelchair can be tipped back allowing a first wheel and a second wheel to move the wheelchair laterally for the purpose of positioning the wheelchair precisely for loading and unloading (for example a passenger vehicle). The lateral movement wheelchair comprises a frame, a first wheel, and a second wheel.

The present teachings provide for wheelchair including a control module, manual drive controls, a camera, biometric sensors, and an antenna. The control module includes an autonomous drive module configured to autonomously pilot the wheelchair. The biometric sensors are configured to measure biometric information of a user of the wheelchair.

After manually setting the length of the variable length connecting element (6) that connects drive unit to the wheelchair with the specified seat length, the drive control sub-assembly (10) starts. The element (6), driven by the drive sub-assembly (10), moves down until it rests on the axle connecting the wheelchair wheels. At the same time, the unit frame (1) whose horizontal segment is placed under the footrest of the wheelchair also moves.

The connecting element (6) that connects the drive unit to the wheelchair as well as the end of the drive sub-assembly (10) whose other end is connected to the connecting element (6) are attached to the frame (1) mounted on the clamp (2) located on the steering system (3). The frame comprises of a horizontal segment and a segment forming an obtuse angle with the ground, while the horizontal part, which, after connecting the unit with the wheelchair, fits under the footrest, has two components (12), (13).

A small electric vehicle includes: a body with a forward, backward, and a width direction; left and right driving wheels in the width direction of the body; free wheels, apart from the driving wheels, in the forward and backward direction; left and right motors to respectively transmit power to the left and right driving wheels; left and right rotation speed sensors detecting rotation speeds of the respective motors; an operation unit with an operation element; and a control unit controlling the motors according to an operation on the operation element, the control unit calculates target rotation speeds of the motors, based on a target vehicle speed provided by an operation position of the operation element, and on a target vehicle angular velocity provided by the operation position of the operation element and by the actual speed of the vehicle, and control the left and right motors such that actual rotation speeds of the motors follow the respective target rotation speeds.

A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

Provided is a wheel (6a) in which a disk (62) includes a ring-shaped rim (60) on which a tire (6b) is fitted, and a disk (62) having a flat circular shape and disposed on an inner circumference of the rim (60). The disk (62) includes a first rib (62a) and a second rib (62b) which extend in a radial direction of the disk (62). A width of each of the first rib (62a) and the second rib (62b) in a circumferential direction of the disk (62) increases toward an outer circumferential side of the disk (62).

A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.

A system, method, and apparatus to provide mobility assistance to disabled persons. The invention includes a self-driving electric cart for transporting a blind or other disabled person along a pre-defined route defined by a path of magnetic markers. The magnetic markers interact through radio waves with a control mechanism on the cart. Utilizing the present invention, the blind person could touch a button on a pre-programmed control screen and ride safely in self-driving carts to any of several specific destinations, such as a job site, grocery store, relative's home, etc.
