Move over, Parrot AR.Drone; there's a new (prototype) quadrocopter in town. For their senior project, electrical engineering students at Northeastern University developed TRAQ, an autonomous aircraft that tracks down the sources of radio transmissions. That functionality comes thanks to a four-element antenna array, and the team envisions such a device being used in disaster, rescue and surveillance situations, where drones could prove faster to respond than us earthbound humans. The next step would be getting multiple aircraft to work together to improve location accuracy. Who doesn't love an imposing swarm of quadrocopters, after all?
