Overview: Droids, bots, and artificial intelligence -- coming soon to rule the world. Right now, robots can clean the house, walk the dog, and identify lifesigns in the rubble of an earthquake. Soon, droids will replace astronauts on dangerous spacewalks and may even act as flying astromech droids to people living in space. How soon will it be before your mother has an unmanned drone to figure out what you're doing all day? Forget about Big Brother -- can the school principal use probe droids to patrol the hallways?
