Claim 13:
14. A method for aligning a first part of an outdoor robotic tool relative to a second part of the tool, wherein the method comprises:
positioning a first magnetic member of a first component to magnetically interact with a second magnetic member of a second component, in order that the magnetic interaction between the first magnetic member of the first component and the second magnetic member of the second component aligns the first part with the second part in a preferred alignment such that when a force causes the first part and second part to move out of the preferred alignment, the magnetic interaction between the magnetic member of the first component and the magnetic member of the second component draws the first part and the second part back into the preferred alignment;
operating the robotic lawnmower to collide with an object such that the case is brought out of the preferred alignment with the chassis by the collision, and
returning the case to the preferred alignment with the chassis by means of said magnetic interaction.
