Japanese robots Kirobo and Mirata set to be launched, literally

Don't get excited about buying the new robots created by Japanese company Dentsu in conjunction with Toyota and the University of Tokyo -- they won't be hitting stores anytime soon. However, do get excited that one of them, namely the white-helmeted droid Kirobo (shown above, left), will actually be launched into orbit as part of a Japan Space Agency mission to the ISS on August 4th. In fact, he and his backup Mirata were endowed with voice recognition, natural language processing, speed synthesis, realistic body language and facial recognition for that very reason. They'll be participating in the "world's first conversational experiment" between people and robots in space, while also mixing it up with kids on earth with educational activities. Hopefully, the astronauts won't give Kirobo any HAL 9000-like control of the station, though the cute 'bots seem malice-free, saying they "wanted to create a future where humans and robots live together and get along." Check it out for yourself in the video after the break.

University of Tokyo’s fast-tracking camera system could revolutionize sports coverage (video)

Researchers at the University of Tokyo's Ishikawa Oku Lab have been hard at work on a camera system that can track fast moving objects incredibly well, and the technology may change the way sports like baseball and soccer are televised. Recently, the team building the system has entered the next phase of testing: taking it outside, to see if will perform as well as it has in a lab setting. If all goes according to plan, they expect it'll be ready for broadcast use in roughly two years.

Demos of the tech are pretty impressive, as you can see in the video below showing the (warning: not recommended watching for those easily prone to motion sickness). To get the ping-pong ball-centric shots, the system uses a group of lenses and two small mirrors that pan, tilt and move so the camera itself doesn't have to. The mirrors rely on a speedy image tracking system that follows movement, rather than predicting it. Swapping the camera out for a projector also has some interesting applications -- it can paint digital pictures on whatever its tracking. Sounds like the perfect gadget for folks who wish their table tennis balls looked like emoji.

Scientists let a moth drive a robot, study its tracking behavior (video)

Scientists let a moth drive a robot, study its tracking behavior (video)

Insect-inspired robots are nothing new, but an insect driving a robot is decidedly novel. Graduate student Garnet Hertz managed to get a cockroach to control a mobile robot back in 2006, but scientists over at the University of Tokyo changed it up a bit by having a silk moth drive a small two-wheeled bot in pursuit of a female sex pheromone. As with the cockroach, the male moth steered the bot by walking around on a rotating ball, no training required. This isn't just for fun and games of course; the eventual goal of the study is to apply the moth's tracking behavior to autonomous robots, which will be helpful for situations like hunting down environmental spills and leaks. Until then, we're crossing our fingers for a moth-driven Monster Truck rally. Check out both cockroach and moth-driving videos after the break.

Update: The university has just released their journal article about the study, which we've linked to in the source.

Add this to the list of terrifying robots we hope to never be chased by. Thankfully, Kenshiro here looks to be fairly slow from the video below. Still, this skeleton-and-muscle headless humanoid robot has secured a place in our nightmares for the foreseeable future, thanks in part to its lifelike movements. The 'bot, which is a followup to 2010's Kojiro model, stands about 5'1 and weighs around 110 pounds. It was developed by Yuto Nakanishi and a team of researchers at University of Tokyo, making its public debut at the recent Humanoids conference in Osaka. You can watch Kenshiro in action after the break.

3D book scanner blows through tomes at 250 pages per minute

3D book scanner blows through tomes at 250 pages per minute

Dai Nippon Printing probably isn't a company you're terribly familiar with, but you might feel inclined to keep closer tabs on the Japanese outfit. With help from the University of Tokyo, Dai Nippon has created a book scanner that can plow through texts at up to 250 pages each minute. A mechanism flips through pages at lightning speeds while a pair of cameras overhead snap detailed images of each sheet as it flies by. Special software then flattens out the photos and turns the picture into a machine readable, 400 pixel-per-inch scan that can easily be converted to PDF, EPUB or other format. Unlike many other high-speed scanners, this doesn't require a book be damaged by removing the pages. In fact, it's quite similar to Google's creation that powers Books. Dai Nippon is actually planning to bring this beast to market sometime in 2013, but it has yet to announce a price.

University of Tokyo turns real paper and ink into a display, could share doodles from a distance (video)

University of Tokyo turns real paper and ink into a display, could share doodles from a distance video

Forget e-paper: if the University of Tokyo's Naemura Lab has its way, we'll interact with the real thing. The division's new research has budding artists draw on photochromic paper with Frixion's heat-sensitive ink, turning the results into something a computer can manipulate. A laser 'erases' the ink to fix mistakes or add effects, and an ultraviolet projector overhead can copy any handiwork, fill in the gaps or print a new creation. The prototype is neither high resolution nor quick -- you won't be living out fantasies of a real-world A-Ha music video -- but the laser's accuracy (down to 0.0001 inches) has already led researchers to dream of paper-based, Google Docs-style collaboration where edits in one place affect a tangible document somewhere else. It's hard to see truly widespread adoption in an era where we're often trying to save trees instead of print to them, but there's an undeniable appeal to having a hard copy that isn't fixed in time.

University of Tokyo builds a soap bubble 3D screen, guarantees your display stays squeaky clean (video)

University of Tokyo builds a soap bubble 3D screen, guarantees your display stays squeaky clean video

There are waterfall screens, but what if you'd like your display to be a little more... pristine? Researchers at the University of Tokyo have developed a display that hits soap bubbles with ultrasonic sound to change the surface. At a minimum, it can change how light glances off the soap film to produce the image. It gets truly creative when taking advantage of the soap's properties: a single screen is enough to alter the texture of a 2D image, and multiple screens in tandem can create what amounts to a slightly sticky hologram. As the soap is made out of sturdy colloids rather than the easily-burst mixture we all knew as kids, users won't have to worry about an overly touch-happy colleague popping a business presentation. There's a video preview of the technology after the jump; we're promised a closer look at the technology during the SIGGRAPH expo in August, but we don't yet know how many years it will take to find sudsy screens in the wild.

Japanese robot trolls humans at rock-paper-scissors, sadly wasn’t named the UMADBRO 9000 (video)

Japanese robot trolls humans at rock-paper-scissors, sadly wasn't named the UMADBRO 9000 (video)

Japan got itself in the good graces of many a Futurama fan after creating Bender's ancestor. Then again, another Japanese robotic creation -- one that specializes in rock, paper, scissors -- may actually have more in common with the morally questionable, beer-guzzling bot. That's because this sneaky little future overlord wins 100 percent of its matches by using an oh-so human trait known as cheating. See, the researchers at the University of Tokyo's 4chan, er, Ishikawa Oku Laboratory programmed the "Janken" robot to recognize its human opponent's hand shape and counter it within a millisecond. Adding to the troll factor is the fact that it was unwittingly named the "Human-Machine Cooperation System" because, well, it needs the cooperation of some poor human sap to work its magic. The achievement joins other man-versus-machine milestones, including losses by humans in chess and shogi. Of course, the question now is, what happens if you pit two "Janken" machines against each other?

Researchers create incredibly thin solar cells flexible enough to wrap around a human hair

You've probably heard that the sun is strong enough to power our planet many times over, but without a practical method of harnessing that energy, there's no way to take full advantage. An incredibly thin and light solar cell could go a long way to accomplishing that on a smaller scale, however, making the latest device from researchers from the University of Austria and the University of Tokyo a fairly significant discovery. Scientists were able to create an ultra-thin solar cell that measures just 1.9 micrometers thick -- roughly one-tenth the size of the next device. Not only is the sample slim -- composed of electrodes mounted on plastic foil, rather than glass -- it's also incredibly flexible, able to be wrapped around a single strand of human hair (which, believe it or not, is nearly 20 times thicker). The scalable cell could replace batteries in lighting, display and medical applications, and may be ready to be put to use in as few as five years. There's a bounty of physical measurement and efficiency data at the source link below, so grab those reading glasses and click on past the break.
