Turing machine built from artificial muscles may lead to smart prosthetics
In the hierarchy of computing hardware, artificial muscle doesn't really even register: it's usually a target for action, not the perpetrator. The University of Auckland has figured out a way to let those muscles play a more active role. Its prototype Turing machine uses a set of electroactive polymer muscles to push memory elements into place and squeeze piezoresistive switches, performing virtually any calculation through flexing. The proof-of-concept computer won't give silicon circuits any threat when it's running at just 0.15Hz and takes up as much space as a mini fridge, but the hope is to dramatically speed up and shrink down future iterations to where there are advanced computers that occupy the same size as real muscles. Researchers ultimately envision smart prosthetic limbs with near-natural reflexes, completely soft robots with complex gestures and even a switch from digital to analog computing for some tasks. Although we're quite a distance away from any of those muscle-bound ideas becoming everyday realities, it's good to at least see them on the horizon.

Harvard soft robot explodes into action, jumps 30 times its height (video)
Harvard University has pushed its soft robot concept in strange directions, but an exploding robot? That takes the cake. A new three-legged, silicone-based variant of the robot is filled with methane and oxygen that, when jolted with electricity, explode and trigger violent pressure that pushes the limbs off the ground. As you'd imagine, the results weren't exactly timid during testing -- the example robot jumped over 30 times its body height, and it would have jumped higher if not for additional tubing holding it down in the lab. The power easily eclipses that of pure air, and could be vital to rescue robots or other public safety machines that could very literally leap to someone's aid. Don't anticipate exploding automatons on the streets anytime soon. We'll just be glad that, if they do arrive, they'll be trying to help us rather than kill us.

DARPA’s low-cost silicone robot cloaks like a chameleon, treks like a snail (video)
Remember those colorful sticky hands that you used to buy for a quarter from grocery store vending machines? Yeah, this is kind of like that -- except that it's a freaking robot. DARPA is currently working to develop low-cost silicone robots that use both air and fluid to control movement, color and temperature. In the following video, you can see one of these soft contraptions as it journeys onto a bed of rocks and then uses colored liquid to blend into its surroundings. Don't expect this glorious sticky hand to break any land speed records, however; the silicone bot can travel approximately 40 meters per hour, or up to 67 meters per hour without the fluid. (Even the 30 second video, which goes at a snail's pace, has been sped up five fold.)
The current demonstration implements a tethered solution as the robot's source of power, pumps, gasses and liquids, but future developments may allow for a self-contained system. Further, rather than improving the robot's speed, its developers will instead focus on its flexibility as a means for navigating within tight spaces. Be sure to peep the video below, and we think you'll agree that DARPA's creation easily puts those sticky hands to shame.
