Automotive inspection device
First Claim
1. An automotive device for the inspection of spaces having ferromagnetic surfaces comprising:
- at least two magnetic contact locomotion devices that allow movement of the automotive device along the spaces whereinthe device includes actively powered rotating arms attached to at least one of the contact locomotion devices, where each rotating arm has a length from its rotation axis to its end that is longer than a shortest distance between the rotation axis of the rotating arm at the device and the ferromagnetic surface, and the rotating arm, when directed toward the surface, being in non-magnetic contact with the surface and there is an air gap between the surface and at least one contact locomotion device, the air gap having a distance in which the magnetic force between the at least one contact locomotion device, and the ferromagnetic forces are reduced to a level that the at least one contact locomotion device is able to move along the spaces.

Abstract
An automotive device for the inspection of internal spaces having ferromagnetic surfaces includes at least two magnetic wheels (3) or caterpillars, or at least two magnetic legs for the advancement of the device along the surfaces to be inspected. According to the invention, the device includes actively powered rotating arms (1) attached to a wheel (3), caterpillar, or leg of the device. Each rotating arm (1) has a length longer than the shortest distance between the point of attachment of the rotating arm to the device and the surface. When the device is in a position, where there is magnetic contact to the surface in two or more points and the device is no longer able to advance due to the strength of the magnetic forces, the rotating arms are brought into non-magnetic contact with the surface in order to create an air gap between the surface and the magnetic wheel and thus reduce the magnetic forces. The device is thereby enabled to overcome the magnetic forces and advance the device along the surface.
