Tokyo University of Science shows off robotic suit powered by pneumatic artificial muscles (video)
What can one do with a robot suit? Well, it's certainly not limited to just lifting sacks of rice, but that was exactly what we got to do at CEATEC courtesy of Koba Lab from Tokyo University of Science. First seen in 2009, the magic behind this 9kg kit are the pair of pneumatic artificial muscles (aka McKibben artificial muscles) on the back, which are made by industrial equipment manufacturer Kanda Tsushin. When pressurized with air using electrical components from KOA Corporation, the lightweight, loosely-woven PET tubes contract and consequently provide support to the user's back, shoulders and elbows. As such, our arms were able to easily hold two more sacks of rice (making it a total of 50kg) until the demonstrator deflated the muscles. Check out our jolly hands-on video after the break.
New metal mix could lead to cheap, plentiful sodium-ion batteries in gadgets
Lithium batteries very frequently power our gadgets, but the material itself isn't common and, by extension, isn't cheap. Researchers at the Tokyo University of Science aim to solve that through sodium-ion batteries using a new electrode material. By mixing together oxides of iron, manganese and sodium, Shinichi Komaba and team have managed to get a sodium battery's electrode holding a charge closer to that of a lithium-ion battery while using a much more abundant material. Having just 30 total charges means this simplest form of sodium-ion battery technology could be years away from finding a home in your next smartphone or EV, although it's not the only option. Argonne National Laboratory's Chris Johnson has co-developed a more exotic vanadium pentoxide electrode that could produce 200 charges while keeping the battery itself made out of an ingredient you more often find in your table salt than your mobile gear.

Tokyo robosuit could make you the sack lifting champion
In Japan, the ultimate merit of a robotic suit is measured in sacks of rice. We've seen it before with the HAL-5. The latest suit created by students at Tokyo's University of Science provides enough assistance to the wearer's back to lift an additional 15 to 20 kilograms (that's 33 to 44 pounds) -- in other words, another two bags of rice for five in total. The university's previous robosuit was heavier and more bulky by comparison, in that it provided assistance to both the wearers back and arms (though clearly some support is provided based on the image above). The suit will ultimately benefit factory workers or those with physical limitations when it goes into production sometime in 2010. Outstanding. Surprisingly, nobody from the university seems willing to talk about that kid with sawblade arms in the corner.
