"The Tweenbots project already demonstrated that at least some folks are willing to help a lost robot find its way, but this new ACE bot developed by researchers at the Technical University of Munich has now ramped things up in a fairly big way, with it actually asking passers-by for directions and developing a map as it moves through the city. Apparently, the robot uses a series of cameras to detect people nearby, and it then asks them to simply point towards the destination indicated on its screen, which it is able to recognize, although it does also asks them to confirm the direction on the screen just to be safe. In initial tests, that appears to have been relatively successful, with ACE (or Autonomous City Explorer) able to reach its destination 1.5 kilometers away in five hours after relying on directions from 38 people. But don't take our word for it. Head on past the break to check out its people skills for yourself.[Via Coolest Gadgets]"^^<http://www.w3.org/2001/XMLSchema#string>
