HEIRS OF KEGRESS
Frenchman Adolf Kegress invented a half-track car at the beginning of the last century. It is difficult to say what is more in it - a tank or a car, but at least a steering wheel and front wheels are present. It is interesting that Kegress first realized his idea in metal not in his homeland, but in Russia, where, before the revolution, eccentric inventors could easily find understanding and sympathy in the highest spheres. For example, Mercedes and Russo-Balt converted by Kegress did not carry anyone, but Emperor Nicholas II. The low specific pressure on the ground made it possible not to get stuck in the mud and to overcome the snow virgin snow - for this, skis were fastened to the front wheels. All-terrain limousines turned out to be slow and not too maneuverable, they burned a huge amount of gasoline for a hundred kilometers covered.
Note that on some semi-tracked all-terrain vehicles, the turning radius can be reduced by braking one of the tracks. The element of such cars is mud, sand and virgin snow. So they were used (and quite widely) during the Second World War. In the post-war period, many of the surviving semi-tracked vehicles were sold to civilian users and converted for peaceful purposes - for example, for the construction of pipelines. Such machines found another application in agriculture, since they could work, say, in water-flooded rice fields.

Perhaps today it is only on agricultural machines that you can see the Kegress mover in action. Moreover, during the rallies of war veterans. Surprisingly, WWII half-tracked vehicles are still on the move!
PRINCIPLE OF MEAT GRINDER
Another exotic mover resembles a meat grinder auger. Machines are called augers. The idea is so simple that it occurred to Jacob Morat back in 1868. The main rules: there should be an even number of screws (at least two), and they should rotate in different directions, otherwise the machine will go not forward, but sideways. A huge advantage of such a mover is buoyancy. A hollow cylinder with a welded spiral does not sink in water, which means that there are no barriers to the auger. Just do not get lucky: the auger operates on the surface on which it moves, like a meat grinder.
To turn, the steering wheel is not twisted - drags are braked, as on a tank, changing the rotation speeds of the right and left augers. True, the auger cannot turn around in place. But he doesn’t need it: he chose the compass direction - and only forward!
