Over the next two weeks 14 teams of arial robot warrior developers will fight it out in a UK Ministry of Defence Grand Challenge in the Wiltshire countryside in the mock village of Copeland, an army testing area that is a replica of a former East German village used during the cold war. The robots include a swarm of miniature helicopters and variety of sensor laden arial drones. http://news.bbc.co.uk/1/hi/technology/6919271.stm
