Tech Roundup: Drones for AV 2019

Since we began hearing about their military use in regional conflicts nearly thirty years ago, drones have been a target of fascination and they have grown as a source of fun, annoyance, promise and danger. When the old hobby model aircraft traded in their strings for RF links and strapped on cameras, they set a course for making artistic and utilitarian history. The drones for AV surveyed here provide an overall view of where we are, what we can do and perhaps most importantly, where drones are taking us.
