Unmanned Aerial Vehicles (UAV), or drones will soon do your spraying. But it won’t be a single, bigger, faster drone. It will be swarms. Cloud-enabled swarms of small drones will spray, computer driven through the cloud, each picking up where the other left off, returning to the home base for a fast swap of a new battery and quick-change chemical tank. The whole operation takes only one person, with computers doing the brain work. And this is in the retail market in China right now.
