I just got sent this link to a Washington Post blog. The video is cool in a technology sense, but scary in a "Terminator" kind of way.
A group of researchers have taken micro robotic technology the next step. I have hear and read that robotic research into antonomous flying robots that can communicate with each other is a hot research topic. The following video shows a group that not only has developed single vehicle flight vehicles that do high stress manuvers but now they have "swarms" (scary but accurate name) that can do tricky manuvers including figure 8s. As my brother said "cool but creepy"
cool yet scary video.
