Nothing beats combining your fears into one, absolutely terrifying object. This is a robotic snake that, when necessary, can blow itself up. Yes, a suicide-bombing robosnake.
Developed by the Israeli army, this robot is primarily intended to be used for surveillance, slithering around with a camera on its front. But if need be, it can be wired up with explosives just in case it finds itself somewhere that would be better suited as a pile of rubble.
Just look at that herky-jerky motion! It's the stuff of nightmares! [Jerusalem Post via Engadget via BotJunkie]
