Bluetooth Bots

I had a flash of thought this morning when I sawthis article on BoingBoing.net. Future semi-autonomous robots will likely have a crawler unit and an airborne unit. The crawler is relatively slow but contains the brains, the airborne unit(s) will carry the sensor package. For example, the crawler moves along an isolated facility perimeter controlling airborne units that can look over and around things that a ground unit would have trouble with. The crawler unit might have a dock where the airborne units would be stored and recharged; perhaps they would only be deployed when an area of interest was unobservable by the crawler.
