<p>According to the invention, a path (109) is determined by the following iterative method: an arc-shaped path (109) about the reference position (106) at a defined distance therefrom is determined step by step and the absence of obstacles a(103) long the arc-shaped path (109) is verified. As long as no obstacles (103) are detected the arc-shaped path (109) is extended. If an obstacle is detected the distance is increased by a defined value and the process is continued using a new iteration and the increased distance.</p> |
