This swarm of drones can think for itself

These drones think for themselves as they fly across the sky together. The largest-ever group of drones flies without human control or programming, unlike the synchronized drones at the 2018 Olympics or the Super Bowl. To build the drones, a group of European scientists studied flocks of birds and schools of fish to understand how animals move as a group. The drones could help with rescue missions, environmental monitoring, precision farming, even fighting forest fires. SUBSCRIBE: FO
