With their unique maneuverability, drones and flying robots are used for all kinds of work. Drones can save lives in disasters. They fly over and photograph disaster-stricken areas so relief workers can find those who most need help. Drones can also be a farmer’s best friend-they help farmers check on crops from the sky, saving them time, money, and a whole lot of work. Discover more fascinating facts about drones and flying robots-from who first invented them to how we’ll use them in the future-in this up-close look at cutting-edge technology!
