Earlier I embedded a video about autonomous quadrotor flight. I checked back on the channel on You Tube and found a new video with the same quadrotors able to cooperate and grasp several objects and move them. Basically multiple autonomous drones can now work together to complete a goal. In my earlier post I thought that one of these would make a great gift simply because it would be fun, but now I see all kinds of practical uses for them: get the groceries from the car, bring me the remote, destroy mankind. The people at the University of Pennsylvania are working on some very neat stuff and I am excited to see what else they can come up with.
