Based on their findings on the collective behavior of birds such as pigeons, his team of Hungarian researchers created 10 self-organizing drones that follow rules of collective motion. "We came to the conclusion that one of the best ways to understand how animals move together is to build robots - flying robots", said Vicsek.
Equipped with GPS trackers and radios that allow them to navigate in formation, the quadcopters were tested in open-field environment for maximum authenticity. Instead of a central control, the drones use a flocking algorithm when their flying path becomes jammed, and wait for their turn while hovering in place.
