Abstract:
1. A method for determining the position of a hand-held power tool on a wall by measuring distances within a plane perpendicular to a tooling axis in at least two directions, comprising: at least one non-contact measurement sensor module in each of the at least two directions measures distances in a multitude of angles in an angular range of at least 1° around the at least two directions, the at least two directions comprising at least the direction to one wall adjacent to the wall and the direction to the floor or the ceiling adjacent to the wall; from the distance sequence measured by the at least one measurement sensor module a calculation and storing unit automatically calculates a function, wherein extrema represent shortest distances to walls, floor and/or ceiling adjacent to the wall; from said function the calculation and storing unit deduces the shortest distances to walls, floor and/or ceiling adjacent to the wall; and output means that provide information about the shortest distances so as to allow positioning relative to the shortest distances.
