A method includes receiving sensor data relating to an environment from a plurality of mobility deices, determining locations of one or more points of accessibility within the environment based on the sensor data, creating an environment map based on the sensor data, and transmitting the environment map to a mobility device. The environment map includes the one or more points of accessibility.

An apparatus for moving a wheelchair, the apparatus having a base including a drive motor drivingly connected to a drive wheel and a first forwardly extending lower arm member engageable with the wheelchair when the wheelchair is in the engageable position. The first lower arm member is operable between a lowered position in which the first lower arm member is disengaged from the wheelchair and a raised position in which the first lower arm engages the wheelchair. The first lower arm member has a first stop member whereby, when the first lower arm member is in the raised position and engages the wheelchair, and when the wheelchair is on a forwardly extending declined surface, the first stop member inhibits forward motion of the wheelchair.

An auxiliary drive device for a wheelchair has at least one electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The electrically driven drive wheel is supported at a steering shaft and freely pivotable with respect to the auxiliary drive device. The steering shaft is arranged such that, when the auxiliary drive device is coupled at a wheelchair ready to be operated, a castor is provided for the electrically driven drive wheel.

Provided is a robot including a seating body provided with a seat and an armrest body and a steering, the steering housing has an opening in an upper portion thereof and an inner space therein is disposed on the armrest body. The steering includes a handle and a lower portion passing through the opening, the lower portion being accommodated in the inner space and an elevator accommodated in the inner space, the elevator being connected to the lower portion of the steering body to elevate the steering body.

A mobility device positionable between a powered transport position and a powered wheelchair position is provided. The mobility device includes a frame including a pair of side rails, a pair of wheels on each side rail, a distance between each wheel on a corresponding side rail defining a length of the mobility device, a pair of arms coupled to an end of the pair of side rails, and a seat member positioned between the pair of arms. A pair of foot plates is pivotally attached to the pair of side rails and rotatable between an unfolded position in which the foot plate is horizontal and a folded position in which the foot plate is vertical. Each foot plate having a length at least substantially equal to the length of the mobility device.

A multifunctional mobility device includes a frame that is configurable between a plurality of modes corresponding to at least a power wheelchair mode, a power scooter mode, and a power walker mode, a plurality of motorized wheels mounted to the frame, and handles pivotally coupled to the frame and communicatively coupled to the plurality of motorized wheels. Pivoting the handles operates the plurality of motorized wheels, wherein each handle is independently pivotable to independently drive rotation of a motorized wheel of the plurality of motorized wheels.

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 wheelchair including a steering assembly configured to selectively attach to the wheelchair, the steering assembly including a steering member, a front wheel operably connected to the steering member, a frame assembly configured to carry the steering member and the front wheel, and a mounting assembly coupled to the frame assembly, and a drive assembly coupled to the wheelchair. The drive assembly is configured to operate in a first configuration in response to the steering assembly being detached from the wheelchair, and the drive assembly is configured to operate in a second configuration in response to the steering assembly being attached to the wheelchair.

An alignment system for a wheelchair based steering column includes a fork assembly configured to carry a front wheel, a bearing coupled to the fork assembly, a tube member that receives the bearing and a portion of the fork assembly, a cam defining sloped cam surface leading to a recess, the cam positioned in the tube member, a biasing member configured to apply a restoring force onto the cam, the biasing member positioned in the tube member, and a steering device coupled to the fork assembly. In response to applying a rotational force to the steering device, the fork assembly rotates, responsively rotating the front wheel and sliding the bearing along the cam surface away from the recess, the cam responsively linearly translates relative to the fork assembly overcoming the restoring force.

A steering system for a wheelchair includes a steering device configured to be engaged by a user, a front wheel operably connected to the steering device, and a frame assembly configured to carry the steering device and the front wheel. The frame assembly is configured to removably engage a mounting member of the wheelchair. A mounting assembly can be coupled to the frame assembly. The mounting assembly is configured to selectively couple to the mounting member of the wheelchair and selectively electrically connect to a motorized drive assembly coupled to the wheelchair.
