Controllable vehicle for inspecting limited access areas

摘要

A vehicle and its control system is disclosed for inspecting or servicing a remote limited access location. The vehicle has a drive frame comprised of first and second opposing legs, and third and fourth opposing legs pivotable connected to the first and second legs to form a parallelogram. A drive mechanism is interconnected between the first and second legs of the parallelogram drive frame for opening and closing the drive frame. First and second attachment devices, illustratively in the form of magnets, are also attached to the first and second legs. The vehicle control system taking the form of a programmable computer in an illustrative embodiment of this invention responds to the opening and closing of the drive frame for alternatively actuating and deactuating the first and second attachment devices, whereby the vehicle is controllably driven.
