We all know what drones can do in the hands of the military and law enforcement. For recreational use, they’re fun to fly around with a GoPro strapped to its belly. The commercial use of drones is in its infancy. Congress passed a law last year requiring the FAA to open the skies to wider drone flights by 2015. Once the happens, the FAA estimates that within five years there will be about 7,500 civilian drones in use. According DIY Drones’ Chris Anderson, one of the areas we’re likely see more drones is a place that doesn’t come to mind when we think about aerial robots: farms.
