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 wheel, a base member, a leg coupled to the wheel and the base member, the leg including an upper leg segment, a lower leg segment positioned below the upper leg segment, a joint positioned between the upper leg segment and the lower leg segment, the joint including a cam defining a non-circular perimeter, and an actuator coupled to one of the upper leg segment and the lower leg segment, the actuator including an engagement member that is engaged with the non-circular perimeter of the of the cam of the joint, where the actuator selectively moves the engagement member to move the cam and the upper leg segment and the lower leg segment about the joint.

A support device includes a wheel, a base member, a leg coupled to the wheel and the base member, the leg including an upper leg segment, a lower leg segment positioned below the upper leg segment, a joint positioned between the upper leg segment and the lower leg segment, and an actuator engaged with the upper leg segment and the lower leg segment, where the actuator includes a linear engagement member that is engaged with one of the upper leg segment and the lower leg segment, a cammed member defining a non-circular perimeter engaged with the linear engagement member, and a motor engaged with the linear engagement member through the cammed member.

A mobility support device capable of stably climbing a step without impairing mobility on flat ground is provided. The mobility support device includes a front wheel, a rear wheel, a drive wheel disposed between the front wheel and the rear wheel, a first link coupled to the front wheel, a second link connecting the drive wheel and the rear wheel, a rotation joint coupling the first link and the second link at a first position, and a first elastic member coupling the first link and the second link at a second position different from the first position.

Embodiments described herein are directed to a wheelchair system that includes a wheelchair and an exoskeleton. The wheelchair includes a frame, a pair of armrests coupled to the frame, and a control unit. The pair of armrests movable between an attached position and a detached position. When in the attached position, each one of the pair of armrests are coupled to the frame and when in the detached position, each one of the pair of armrests is removed from the frame. The exoskeleton is communicatively coupled to the control unit via a cable extending between the exoskeleton and the control unit. The exoskeleton being releasably coupled to at least a portion of the frame of the wheelchair. The wheelchair system is translatable between a wheelchair mode and an exoskeleton mode such that, when in the exoskeleton mode, the control unit provides electrical power and control signals to the exoskeleton.

A transport apparatus has a mobile chassis, a lifting mechanism, two armpit supports structured and operated mirror-symmetrical to one another, and two seat assemblies. The lifting mechanism includes a lifting arm for assembling a chest rest and two lifting racks, and a linear actuator driving the lifting arm to pivot upward or downward. The armpit supports are assembled on the lifting racks and transversely extend toward a rear of the mobile chassis. The seat assemblies are assembled on the mobile chassis. Each of the seat assembly has a seat plate driven to rotate by a drive motor to form a seat. The weak person can be moved directly by the transport apparatus with voice command or with a remote control. Since the weak person is not moved by the care workers, the weak person can be moved in an easier and safer way.
