Yeah, this one's been slithering around the alleyways of the web for a tick, but it's just too hard to ignore a vicious looking viper created entirely from unwanted keyboards (okay, so glue and a faux tongue were involved, too). Still, the best part isn't the unquestionably amazing use of the dreaded Caps Lock key, it's the crowd of mice this thing is getting ready to feast on. Better check yo'self before you wreck yo'self, kids.

Apparently the Biorobotics Lab at Carnegie Mellon University has been quite busy as of late... building an army of robotic snakes. Though we've seen droid snakes before, bot-makers at the school have been investigating the myriad possibilities of single-task snakes, coming up with configurations for swimming, crawling, and climbing, amongst others. The program is concerned with enabling the bots to take on a diverse variety of terrain and tasks, made easier by the fact that the little guys aren't limited to wheel-based movement. To really get an idea of the possibilities (and extreme creepiness), check the video after the break. We just hope you enjoy the techno version of Crazy Train as much as we do.

We'll be honest -- we've seen more snake-like robots than we care to count, but a new creature slithering out of the Norwegian University of Science and Technology is noticeably different than most. As you can see above, there's a distinct lack of treads, tracks or wheels on Aiko, as it actually pushes off foreign objects it encounters in order to creep forward. Additionally, researchers have created a "virtual double" of the critter in order to help guide the development of the actual robot, though we've yet to hear if it plans on joining Anna Konda in war on fire.

Although DARwin looked to be a fine effort from the US of A, Aske Olsson and Lars Pontoppidan's entry relied on a more down-low approach to taking care of business. Their SickSack robotic snake chose to crawl rather than run, but the uniqueness of the creature's movement most definitely deserve props. Gearing up a series of rollers to blast across the raceway isn't all that impressive, but the SickSack's use of passive wheels combined with mechanics that enabled lateral undulation made this thing about as beastly as a metal-clad bot can get. It also featured eight Futaba servos, a microcontroller, and a good bit of wiring and programming for its locomotion, and it (rightfully) took home the award for best design / effects at RoboCup 2007.

The Johns Hopkins University must employ some seriously bright folks, as researchers at the school are unveiling yet another marvel to benefit mankind, and this time their creation is headed for the nooks and crannies within your body that surgeons have difficulty reaching unassisted. Sure, the diminutive locales within your guts have been explored by robotic creatures before, but these "snake-like robots" could enable surgeons, operating in the narrow throat region in particular, to make "incisions and tie sutures with greater dexterity and precision." The invention consists of two thin rods tipped with "tentaclelike tools" capable of moving with six degrees of freedom; during surgery, the doctor would utilize a 3D visualization system to watch, control, and dictate the robotic tubes. Moreover, the snakes are crafted from nonferrous metals so it can be used around magnetic imaging equipment, and considering its ability to "make up 100 adjustments per second," nimbleness is in its nature. But if you're not exactly fond of such slithering creatures, you've still got time to escape, as researchers estimate that there's still about "five more years" of lab testing before we see Snakes on a Hospital Bed.

Sure, we've seen plenty of robot snakes in the past, but none like this robot earthworm being developed at Chuo University in Japan. The same research department that showed us the incredible Strider bot, is now demonstrating a machine that can move on open land and along narrow passageways, using the same method of peristalsis as the average night crawler. Each section of the body expands and contracts in a specific order, thus enabling the rubber-gripped bot to move inside of a tube with almost no lateral motion, even when crawling straight up.  We can see how this technology, which NASA is also working on, could be used in fields like geology, robofishing and medicine, even though watching the videos on the site and seeing the word "catheter" in the article made us more than a little uneasy.
