Headless Kenshiro muscle-bot gets ripped at the gym

Is a robot with muscles and bones any more freaky than one with servomotors?

Researchers at the University of Tokyo have been building a humanoid robot called Kenshiro that moves around with muscles that work with small pulleys.

Initially developed as a scrawny kid-bot in 2001, Kenshiro has been packing on muscle mass. With a total of 70 degrees of freedom, or axes of motion, it now has 160 muscles, with 22 in its neck, 12 in its shoulders, 76 in its abdomen, and 50 in its legs.

But it's still designed to mimic the body of a 12-year-old Japanese male, standing 5 feet and 2 inches and weighing 110 pounds. It also has a human-like ribcage, pelvis, and spine made of aluminum. … Read more

Cargo ship with metal sails would save 30 percent fuel

Can wind energy really power modern cargo ships? We've seen the idea of hybrid freighters before, but this concept from the University of Tokyo has a remarkable sail system.

A model of the UT Wind Challenger was recently shown off at the Sea Japan trade show in Tokyo. It would have giant telescoping sails that rise above the deck when wind conditions are good.

As seen in the vid below, University of Tokyo professor Kiyoshi Uzawa and collaborators believe this hybrid system could cut fuel consumption by cargo ships by about 30 percent. … Read more

New concept turns pizza boxes, bananas into computers

Though you might be obsessing over the next MacBook Air or the latest and greatest Android smartphone, your future laptop or mobile device might already be lying around your house.

Researchers at the Ishikawa Oku Laboratory at the University of Tokyo have come up with a concept called "invoked computing" that turns everyday objects into computer interfaces and communication devices using a ubiquitous augmented-reality system.

The concept is based on the idea that technology should learn our behavior and respond to us, instead of the other way around. As such, with invoked computing, one would just need to mimic a certain task and the computer should recognize the gesture and turn any object into a usable electronic device. … Read more

IBM hopes to make mobile devices more accessible

IBM is embarking on a research project to design mobile gadgets that are easier to use for people who have disabilities or aren't fully literate.

As part of the project, announced Wednesday, Big Blue will collaborate with India's National Institute of Design and the University of Tokyo's Research Center for Advanced Science and Technology.

The goal is to develop a common interface for mobile devices that will make them easier to use. As digital information becomes more vital, IBM said, it believes the Internet needs to be more accessible to a wider range of people, including those … Read more

My, you have such soft e-skin!

Japanese researchers say they have developed a rubber-like material that's able to conduct electricity, paving the way for robots with stretchable "e-skin" that can feel heat and pressure like humans.

The material, described by Tsuyoshi Sekitani of the University of Tokyo in the journal Science, could be used on curved surfaces or even in moving parts, such as the joints of a robot's arm, the researchers said.

Sekitani's team developed their material using carbon nanotubes, a long stretch of carbon molecules that can conduct electricity. They mixed these into a rubbery polymer to form the … Read more
