Modern Marvels: It all started with the vision of the legendary scientist Nikola Tesla, who built a remote controlled, steam-powered boat in 1898. A little over a century later, unmanned vehicles have taken us on vicarious journeys to the surface of Mars and deep into space, helped locate scores of shipwrecks, and been sent to work in conditions where humans would never survive.
