Robot Holocaust IV--Slitherbots!

Fans of the Book of Genesis (if not the band Genesis) can interpret this however they like, but whatever your theological orientation, it can't be good:

The Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slither through collapsed buildings in search of trapped victims. In recent weeks, Choset and some of his students got the remote-controlled devices to climb up and around pipes.

Rescue workers say such robots would help locate survivors.

Yes...survivors...of the robot holocaust! And why would these slitherbots want to locate the survivors? You figure it out....
