Scientists have built what they say is the first flying machine that hovers in a stable manner by flapping its wings.
Previous designs for so-called flapping wing aircraft have mimicked the wing motions of insects, but the new design is based on the way jellyfish swim. The prototype built by scientists at New York University is able to keep upright and recover from disturbances. The authors say their machine shows the value of researching flying strategies not yet explored by evolution. The work by Leif Ristroph and Stephen Childress from New York University (NYU) is published in the UK Royal Society journal Interface. Most efforts to build stable flapping-wing aircraft - or ornithopters - have based their designs on the way insects fly. But this approach leads to aircraft that are inherently unstable, tending to flip over if left to their own devices. Stabilising these designs requires either active control systems, or the addition of sails and tails that act as aerodynamic dampers. Using jellyfish as one inspiration, the researchers set out to achieve stable hovering using flapping wings alone. They developed a 10cm prototype with four distinct wings that demonstrated an inherent tendency to remain upright during flight. “In the future, small-scale flapping-wing aircraft may be used in applications ranging from surveillance and reconnaissance missions to traffic and air quality monitoring,” the researchers write in Interface journal.

A Group Of Teenagers With A 3D Printer Just Gave This Little Girl A Life-Changing Christmas Gift
A group of high school students in Michigan gave a 4-year-old girl the gift of a lifetime yesterday. The robotics team from West Catholic High School presented little Harmony Taylor with the right hand she never had, after the teenagers spent six weeks to build the hand from a 3D printing device that was donated to their school. Harmony was born with “limb differences”, which caused the fingers on her right hand to never develop. Mary Free Bed Rehabilitation Center in Michigan also played a role in the creation of the hand, Monica Scott of MLive reports, helping the family connect with the school when insurance wouldn’t cover all of Harmony’s needs.

The Cubli: a cube that can jump up, balance, and ‘walk’
The Cubli is a 15 × 15 × 15 cm cube that can jump up and balance on its corner. Reaction wheels mounted on three faces of the cube rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up. Once the Cubli has almost reached the corner stand up position, controlled motor torques are applied to make it balance on its corner. In addition to balancing, the motor torques can also be used to achieve a controlled fall such that the Cubli can be commanded to fall in any arbitrary direction. Combining these three abilities — jumping up, balancing, and controlled falling — the Cubli is able to ‘walk’.

NASA unveils 6-foot ‘superhero robot’ Valkyrie
Designed to compete in the DARPA Robotics Challenge, this “female” robot could be the precursor to robo-astronauts that will help colonize Mars.
What if NASA’s Robonaut grew legs and indulged in steroids? The result might be close to what NASA has unveiled: Valkyrie is a humanoid machine billed as a “superhero robot.” Developed at the Johnson Space Center, Valkyrie is a 6.2-foot, 275-pound hulk designed to compete in the DARPA Robotics Challenge (DRC). It will go toe to toe with the Terminator-like Atlas robot from Boston Dynamics in what’s shaping up to be an amazing modern-day duel. In an interesting twist, Valkyrie seems to be a girl. While officially genderless, “Valkyrie” (a nickname, since the official designation is R5) evokes the goddess-like females of Norse myth.

Inside Adam Savage’s Cave: Awesome Robot Spider!
We’re back in Adam’s cave to check out his latest obsession, a robot spider with incredibly realistic movement. Adam shows off the special box and platform he built to tinker and calibrate the spider, and then sends it crawling around the pool table in his shop. It’s not for the arachnophobic!

Last week we talked about Japanese adult toy company Tenga’s robotic hand job machine, which uses a mechanical apparatus to simulate manual sex while a user watches a virtual reality sex simulation. Turns out a company called FriXion is making that experience more intimate — in a way that could help lonely hearts and long distance relationship partners alike. While Snapchat, Facetime, and Skype make it easier to conduct long distance affairs, one still can’t exactly reach out and touch someone electronically. But FriXion is ushering in a new frontier in “robotics-assisted teledildonics.” And, yes, that word does mean what you think it means. In short, FriXion makes robot-assisted sex toys. Using FriXion devices, folks can simulate the feel of everything “from hand holding and kissing up to full penetrative sex.” The most advanced electronics “use real-time bidirectional force feedback telemetry, and can be configured for any gender or orientation,” explains FriXion in language we don’t really understand. It seems that users can connect electronically with people they know, or people they don’t know through a social network platform. The open platform API also allows designers to create their own apps and plug-ins to further widen the scope of robotic sex capabilities. FriXion calls it “an intimate experience straight out of science fiction and for a retail price of less than $200.”
This 6-Foot, 330-Pound Robot May One Day Save Your Life By Jason Kehe
Meet Atlas, the Pentagon’s 6’2”, 330-pound humanitarian robot. He was designed to save lives in disaster zones (like Fukushima). But while this Tin Man has a heart, he lacks a brain. In December, seven teams of scientists from top institutions, including MIT and Virginia Tech, will compete to code the bot for action. Each team will send its own Atlas into Darpa’s trials—eight tasks that will test his ability to navigate degraded terrain, drive a utility vehicle, and enter buildings. “We designed Atlas to facilitate programming, but we expect Darpa to make the competition challenging,” says Marc Raibert, president of Boston Dynamics, Atlas’ maker. Here’s the skinny on the massive bot. (via This 6-Foot, 330-Pound Robot May One Day Save Your Life | Danger Room | Wired.com)
Giant Fembots Dance With Dinosaurs in the Weirdest Show on Earth
TOKYO — Outside, the city is bracing for the most violent typhoon of the past decade, a storm with winds topping 75 mph that’s already dumping endless sheets of rain from the night sky. Yet it all seems mild compared to what’s happening inside a bunker of a theater two floors below the wind and the rain. You sit in the back row, stuffed into something a lot like a grade-school writing desk, a Bento box and green tea untouched on the tray in front of you. The food is almost inedible — cold rice and fish one step below what you’d find in a Japanese convenience store — but even if it were the finest sushi on Earth, you wouldn’t be eating. It’s hard to eat when watching bikini-clad go-go dancers do mock battle with pseudo-metallic automations from some alternate future universe — not to mention the blaring electronica, flashing lights, giant Fembots, robotic dinosaurs, stuffed panda ninjas, roving Segways, rainbow afro wigs, virtual fireworks, kabuki-style play acting, a Captain America shield, medieval iconography, and a sea of waving glow sticks.

Superfast rock-paper-scissors robot ‘wins’ every time
A robot developed by Japanese scientists is so fast it can “win” the rock-paper-scissors game against a human every single time.
The Janken robot - named after the game’s Japanese name - is a faster version of one unveiled by University of Tokyo researchers in June 2012. Version two completes its chosen hand shape almost at the same time as the human hand. It uses high-speed recognition and reaction, rather than prediction. Technically, the robot cheats because it reacts extremely quickly to what the human hand is doing rather than making a premeditated simultaneous action as the rules state. Taking just one millisecond (ms) - a thousandth of a second - to recognise what shape the human hand is making, it then chooses a winning move and reacts at high speed. Version one completed its shape 20ms after the human hand; version two finishes almost simultaneously. The scientists at the Ishikawa Oku Laboratory, part of the University of Tokyo, specialise in a range of technologies, including “sensor fusion”, which aims to replicate and improve upon the human senses using high-speed intelligent robots.

More and more, robots are moving into our everyday lives, and if they’re not going to end up being incredibly annoying, they’re going to have to learn to recognize and cope with human emotions. RoboKind of Dallas, Texas has started a Kickstarter campaign to raise capital for the further development of its Zeno R25 interactive humanoid robot, which is designed to interact with humans in an intuitive way by detecting and mimicking emotions.
