This is just awesome to watch:
http://www.engadget.com/2011/07/28/khepera-swarm-robots-learn-to-build-a-mobile-quadrocopter-landin/Stay with the whole thing, read the text. The robots are acting autonomously based on intention instructions, not absolutely (ie., no X,Y movements etc - move to this relative position behind the leader). I am an optimist regarding the future, but things along this line are moving so fast it's both breathtaking and a little arresting.
Someone needs to re-read the 3 laws of robotics RIGHT QUICK.
