The invention uses specialized wheel sets to navigate over various surfaces. The invention has a primary drive wheel with two outrigger wheels to provide stability. In the basic motorized configuration of the apparatus, the user provides certain hand movements of the control mechanism, which in turn produces control signal(s). Incorporated into the invention is a power lifting mechanism, which aids the user to be elevated from a seated position to a standing position without any assistance. A built-in seat is incorporated within the invention. The built-in seat is a fold down type that is adjustable in height. In the virtual mode, various user motion signals are relayed, by wireless means, to an embedded computer module, within the apparatus. This embedded computer provides control signals to operate the invention. For ease of transport and erection, retractable/deployable units are incorporated into the design of the invention.
