Computers are getting better at spotting objects, but they tend to work in isolation. What good would a security robot be if it couldn't share info about an intruder with other machines? Cornell scientists might have an answer. They're designing a system that would let robots and other autonomous devices cooperate with each other on identifying and tracking objects. Each bot would send its imagery to a central unit that could talk to both other camera systems and the internet to help identify objects. The group would combine and compare images to follow objects and collect more information about them, getting more data than they would if they did all the work by themselves.
