They are tipped to change the world in the same way computers did. Droids, little flying robots capable of almost anything. Attach a camera to them, and you can inspect bridges, powerlines, or disaster-damaged buildings without risk to life, get sweeping aerial shots impossible to achieve with a helicopter, check every animal and paddock in a hill country farm in an hour, and have the images live-streamed to your computer. That is why American aerospace and defence market research company Teal Group estimates this to become a 10 billion dollar market in the next 10 years. And the first company in the world to start selling them for professional use is based in Raglan.
