The present invention relates to a wheelchair that includes a base frame having robotic legs and a seat assembly. A pair of armrests include at least one control stick and an electronic display for operating the wheelchair. A motor receives power from rechargeable batteries and extends or retracts the robotic legs. The legs have big wheels and small wheels that assists in movement of the wheelchair, including ascending and descending a staircase. The small wheels can be raised or lowered as per requirements automatically by the motor using a sensor or manually using the control stick. The wheelchair can be operated remotely using a handheld remote-control device enabling a caretaker to remotely activate and maneuver the wheelchair. The wheelchair enables individuals who use wheelchairs to remain independent even in traditionally non-accessible spaces and offers a way for disabled, elderly, and sick individuals to retain their independence.

A system for use with a mobile device includes at least one sensor to sense a variable related to tilting of the mobile device and at least one activatable system in operative connection with the sensor. The at least one activatable system increases stability of the mobile device upon actuation/change in state thereof on the basis of data measured by the at least one sensor. A variable related to tilting includes variables that indicate concurrent, actual tilting as described herein as well as variables predictive of imminent tilting. Activatable systems hereof change state upon actuation or activation to increase stability of the mobile device by reducing, eliminating or preventing tilting.

A support device includes a base member, a caster assembly coupled to the base member including a caster pivotally coupled to the base member, at least two planar members positioned above the caster and pivotally coupled to one another by at least two opposing hinges, and a shaft positioned between the at least two opposing hinges and extending through the at least two planar members.

A mobility device for moving an object across a surface having a non-planar obstruction to allow movement of the object over the obstruction. The mobility device has a walking wheel assembly and an attachment mechanism. The walking wheel assembly has at least two wheels and an offset camshaft. The offset camshaft has a lobe associated with each wheel. The lobes are in a non-linear relationship such that one wheel is a leading wheel and one wheel is a trailing wheel. The offset camshaft allows the leading and trailing wheels to pivot upward and downward independent of each other. The attachment mechanism attaches the walking wheel assembly to the object. The mobility device can include a deflector assembly having a pair of deflector arms that are pivotally connected to a cam-axle which is attached to the offset camshaft to help guide the mobility device over non-planar areas.

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.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A chassis for a tracked mobility device may include: a battery box floor; a battery box rear wall; a pair of main side rails; a main front cross member; a lower box rear cross member; a pair of side bogie support tubes; a pair of motor support tubes; rear side support tubes; front side support tubes; a pair of bogie support plates; short bogie cross tubes; seat frame plates; a tensioner support frame; a rear cross support plate; motor/gear boxes having floors, rear walls, outer side walls, inner side walls, and outer side wall extensions/gussets; anti-tip tubes; anti-tip cross-members; and anti-tip vertical tie rods. The chassis components may be welded together to provide a rigid, stable, unitary construction.

A support device includes a base portion, a leg coupled to the base portion, the leg including an upper segment, a central segment pivotally coupled to the upper segment at a front wheel, a lower segment pivotally coupled to the central segment, a rear wheel coupled to the lower segment, and an engagement member coupled to the lower segment, where the engagement member is positionable between a disengaged position, in which at least a portion of the engagement member is positioned above the rear wheel, and an engaged position, in which at least a portion of the engagement member is positioned at or below the rear wheel.

A support device includes a base member, a caster assembly coupled to the base member including a caster pivotally coupled to the base member, at least two planar members positioned above the caster and pivotally coupled to one another by at least two opposing hinges, and a shaft positioned between the at least two opposing hinges and extending through the at least two planar members.

A powered wheelchair apparatus includes a chair component, a power base component and a wheelchair control system. The wheelchair control system includes a processor and a user input device communicatively coupled to the processor. A display is communicatively coupled to the processor. A memory module is communicatively coupled to the processor that stores logic that, when executed by the processor, causes the system to receive user instructions from the user input device and display a message on the display based on the user instructions. The display is on a back of the chair component.
