In recent tests at Ft. Benning, Ga. a Northrop Grumman Fire Scout unmanned helicopter ferried a ground robot, the QuinetiQ's Dragon Runner, to its deployment point. The helicopter scanned the ground for obstacles before setting down, releasing the Dragon Runner when the Fire Scout's on-board skid sensors detected contact with the ground. Within seconds, the UAV was hovering overhead, providing a communication relay between the ground surveillance robot and its human distant human controller.
