TED: Vijay Kumar: Robots that fly ... and cooperate
Wow, this is impressive. Most of us have seen the quad-copter robots in action doing various things and this is a TED talk about how they work. A great watch.
In his lab at Penn, Vijay Kumar and his team build flying quadrotors, small, agile robots that swarm, sense each other, and form ad hoc teams -- for construction, surveying disasters and far more.
