China is making 1,000-UAV drone swarms now

According to an executive at Ehang UAVs, which provided the swarm, each drone cost $1,500, which is pretty darn cheap considering their capabilities. Take, for instance, the datalink and software used. It lets more than 1,000 flying robots coordinate autonomously and synchronize movements, with a flight deviancy of a mere 2 centimeters horizontally and 1 centimeter vertically. If something goes wrong and a drone can't reach its programmed position, it automatically lands. In the show last month, these machines created striking formations of China, a kapok tree flower, and a ship.
