Engadget explains your future as a tasty robot morsel:

Oh sure, we joke about rogue AI all the time, and we're aware that we'll probably pollute ourselves to death well before the robots get us, but who really thinks flesh-eating machines are a good idea? Has Morpheus taught us nothing? The (patently evil) scientists behind the EATR project -- no fair, they're making their own jokes now too -- say the reconnaissance bot is powered by foraging for and consuming biomatter, which to you and us simply means soft, pulsating, yummy humans. They call it fuel versatility, as gasoline, diesel, and solar power may also be used if available, yet we'll offer no prizes for predicting which energy source these chainsaw-equipped robots will prefer.
