But for all the passion, suspicion and ethical questions about unmanned aircraft and privacy, researchers have been working with drones in many fields—beyond retail—for years. Consumers already have been exposed to the iRobot vacuum cleaner. A more serious application has been unmanned aircraft used in modern warfare.
