aka drone - Historically, UAVs were simple drones (remotely piloted aircraft), but autonomous control is increasingly being employed in UAVs. UAVs come in two varieties: some are controlled from a remote location (which may even be many thousands kilometers away, on another continent), and others fly autonomously based on pre-programmed flight plans using more complex dynamic automation systems. http://en.wikipedia.org/wiki/Unmanned_aerial_vehicle
