The wheel is considered as on of the largest inventions of humans. But just this round achievement, swivelling around an axle, which, as a progressive movement, influenced human life so lastingly, is not known by nature. Are we superior to nature for once?

By no means, if one looks at the close boundaries of the application of wheels.

The wheel requires even, obstacle-free roads or rails and is helpless in hard-to-travel area, in mud, sand, ice and snow. Nature sets legs to that as movement organs in return. Legs are usually decisively superior to wheels.

The bionic robotics studies the methodology and controlling of natural run apparatuses, e.g. with insects, and uses these realizations to the building of run machines.

Staff grasshoppers have six long legs. Perhaps the run machines of the future will look like enormous insects. Staff grasshoppers need a minimum of energy, are in the energetic equilibrium and lead back their waste usually completely again into the natural cycle. They are far pollution free thereby and more economically than the products of the today's technique.
