I created the all-terrain vehicle (developed design and manufactured a working model) is designed for movement in cross-country. The Rover has a two-piece articulated frame and wheels in the form of hemispheres. The turns are produced by the simultaneous “turning point” of the frame and tilting of the two axial pairs of wheels, and therefore the maneuverability of the Rover is almost the same as that of tracked vehicles.
The main advantage of providing off machine — pestiferously the permanent all-wheel drive even turns on solid ground. Angular velocities of all wheels is the same, but the diameter of the running-in of internal and external (relative to the center of rotation) is different, due to their shape.
