Eigenfortbewegungsfähige Vorrichtung

摘要

The device has two propellants that are in contact on a vast surface, and stays in active connection with one another. Each propellant has a surface contact area that moves around interspersing rotation axis, and produces a sliding frictional force that is not equal to zero. The resulting friction forces produced by the propellants cause the self-progressive movement of the device. An Independent claim is included for the use method of the self-progressive mobile device.
