A wheelchair includes a frame, a seat attached to the frame, a first forward wheel on a first side of the frame and a second forward wheel on a second side of the frame, a first rearward wheel on the first side of the frame and a second rearward wheel on the second side of the frame, a first drive wheel on the first side of the frame positioned intermediate between the first forward wheel and the first rearward wheel and a second drive wheel on the second side of the frame positioned intermediate between the second forward wheel and the second rearward wheel, and actuators to independently control the vertical position of the first forward wheel relative to the frame, the vertical position of the second forward wheel relative to the frame, the vertical position of the first rearward wheel relative to the frame, the vertical position of the second rearward wheel relative to the frame, the vertical position of the first drive wheel relative to the frame and the vertical position of the second drive wheel relative to the frame.

A user control device for a transporter. The user control device can communicate with the transporter via electrical interface(s) that can facilitate communication and data processing among the user interface device and controllers that can control the movement of the transporter. The user control device can perform automated actions based on the environment in which the transporter operates and the user's desired movement of the transporter. External applications can enable monitoring and control of the transporter.

A powered pedestrian apparatus is provided having two vertical panels, two rotatably connected articulating arms capable of rotating about a center point, a vertical lifting device located within said panels attached to said arms, and a foot platform wherein one or more of an electric motor, front tires and caster wheels enable movement of the powered pedestrian apparatus.

A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The levers are connected to a tooth clutch mechanism that allow the user to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.

A convertible wheelchair system, between a wheelchair configuration and an all-terrain configuration, is provided. Embodiments include a central frame aligned along a central longitudinal axis, the central frame having a front and back bar parallel to each other and orthogonal to the central longitudinal axis, paired side bars aligned with the central longitudinal axis, and paired wheel cages, aligned with the central longitudinal axis and attached to the front and back bars, each wheel cage supporting an axle and a wheel mounted thereon. The system further includes a forward beam alignable with the central longitudinal axis, configured to support a forward wheel, and reversibly attached to the front bar. The convertible wheelchair is in the all-terrain configuration when the forward beam is attached to the frame, and the wheelchair configuration when the forward beam is detached from the frame, the central frame thereby standing without the forward beam.

The present disclosure includes methods of operating a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair. The methods adjust the maximum operational speed of the wheelchair when the seat is in an elevated position based on sensor data relating to one or more of the arm limiter position and the position of the frame.
