Robots that fly, robots that roll, rotors that cooperate. This article http://www.newscientist.com/article/dn20791-robot-mission-impossible-wins-video-prize.html?DCMP=OTC-rss&nsref=robots shows a video about how a swarmanoid finds a book in a house. It fun, but also has a serious application. How about these robots being first in to a mine rescue, they can quickly map the situation, set up communications, and guide in the rescue team. Have a look at the video.
