Just when we thought the fight couldn't get any harder against our soon-to-be robotic overlords, the Defense Advanced Research Projects Agency (DARPA) decides to screw us over. They've issued a request for shape-shifting robots, bots that can "manoeuvre through openings smaller than their static structural dimensions." These so-called chembots would be like rats, which can squeeze their way into crevices smaller than their actual size. Essentially they want a T-1000. Yep, we're screwed.
