We occasionally joke about the looming robot menace, but seriously. Discoblog has picked out the Niftiest Robots of 2009, but "Scariest" would have been an equally appropriate appellation. Yes, there is a robot that crawls around inside your colon, not to mention a Japanese emobot, but the one I would least like to meet in a dark alley is Chembot. It's a blob-shaped thing that uses jamming in granular materials to make a robot that can alter its shape. Still pretty primitive, but you can see where we're headed here. Don't say we didn't warn you.
