Abstract: A device adapted for movement over inclined surfaces and inverted surfaces. The device comprises at least one front wheel mounted for rotation on a body potion having at least one means for abutting against the inclined surface. The abutting means may be displaced rearwardly from at least one front wheel. The front wheel or wheels may comprise a layer of sticky material that is adapted for providing temporary adhesion to the inclined surface where the sticky layer enables adhering the device over the surface at least during motion of the device there over. The surface of the front wheel(s) may be rough to enlarge the contacting-area between the front wheel(s) and the inclined surface. The device may further comprise suitable motor means operatively connected to at least one front wheel for providing a locomotive force thereto.
