These are the Swarm-bots, and really, you don't need to know anything else to judge them. At no point in history has the term 'swarm' been applied to something pleasant -- you don't buy your kids "a swarm of ice cream cones," and you don't receive "a swarm of blowjobs" -- it's always something that wants to sting you, kill you, and lay eggs in your inexplicably-still-screaming corpse. The Swarm-bots are no exception to the rule: Built by Intelligent Design Systems, the same collective that brought us robots who learned how to lie, poison and murder (as covered in the sexiest tome of knowledge ever collected,) the Swarm-bots are seen here demonstrating their teamwork and problem solving skills. IDS figured the best way to really illustrate the implications of robots learning these lessons was to videotape them ganging up on, and then dragging away a terrified child.
"Intelligent Design Systems: We ain't front; our robots eat kids."
The girl was bribed into participating in the Swarm-bot demonstration, but it's obvious she doesn't want that Barbie anymore - her only Earthly desire at this point is to not be pulled away and deconstructed into her base elements to build other Swarm-bots. But she's going to learn a hard lesson about life, because that's exactly what's going to happen here. Look at the expression of terror on the girl's face at about 2:30: She's clearly been paralyzed or drugged somehow, left aware but unable to move or cry out. This video isn't a "demonstration of concept," it's a slow motion techno-Mayan sacrifice.
Researchers at Japan's Tohoku University went and built a robot designed after a millipede. That's not "beginning with good intentions and accidentally unleashing a horror," that's starting right off at creepy then hopping onto the Terror Expressway: Millipedes are infamous solely for their gross and unsettling locomotion, undulating along, like they do, on their thousand scrabbling little legs. So you went ahead and built a robot that does that too, except it's also eight meters long, translucent, and hairy. What was your business proposal? "Gentlemen, I want to take the worst elements of giant snakes, deep sea creatures, and spiders, then build a robot out of them!" And when they asked toward what end -- what possible use could one have for this flailing robo-tentacle raping machine - you had the balls to answer: "Rescue!"
"Revenge against my bitch of an ex-wife! She'll never forget that COCKtail party! MWAHAHA...I mean...uh...rescue!"
The Millipede Bot (or Active Scope System) has a camera built into the head, and is meant to snake it's way through the rubble left behind by earthquakes to locate trapped survivors. The first thing they tell you, should you ever find yourself trapped in an enclosed space, is not to panic; you'll just make it worse.
...and then they send the Squirming Avatar of Panic to crawl out of the cracks in the darkness and writhe all over your body while you wait to be dug out. Presumably while the rescuers take bets on how long it'll take you to hyperventilate all the oxygen out of the room and die of asphyxiation.
