Space.com has an article about space robots to hunt space rocks to protect earth. Movies like Meteor, Asteroid and Armageddon help us to imagine blowing up space rocks with nuclear missles, and saving the Earth, but neuclear robots really are being developed to save Earth from Asteroids. Called MADMEN (Modular Asteroid Deflection Mission Ejector Node), these swarm robots will attack an asteroid and try to deflect it away from the earth. MADMEN will work by drilling bits of rock and throwing them away pushing the asteroid in the other direction. Over time the asteroid will move faster and faster in the opposite direction and away from Earth. SpaceWorks Engineering, Inc. (SEI), the maker of MADMEN has won a NASA award to study Near-Earth Objects (NEO) and an approach to defend against asteroid impactors. Perhaps it's just in time to keep the Earth from being destroyed in 2019!
