Robots are getting better at finding their way around unknown areas, and making their own maps as they explore. But robots lost in urban areas don't need to rely on their own faculties to get from place to place, German roboticists have shown.
Their mobile robot simply rolls up to any humans nearby and asks for directions. By using that strategy, their robot has become one of the first to be properly let loose in the real world, not just carefully controlled environments.
Martin Buss's team at the Technical University of Munich dumped their mobile robot outside the university and instructed it to find its way to the Marienplatz in the center of Munich, some 1.5 kilometers away.
