Robots; no longer just good for fighting Darth Vader. Flying robots (also known as drones) could soon be used to safeguard millions of miles of highway in the country. Drones could apparently be used in the future to inspect bridges and roads, survey land with laser mapping and even alert officials to traffic jams or collisions.

A project studying the use of drones recently received $74,984 from the Federal Highway Administration and the Georgia Department of Transportation to figure out how drones can help highway workers.
LiveScience has the details.
