Robotic space 'hedgehogs' under development

We already know how to explore planets with relatively low gravity, like Mars. The Curiosity Rover is engineered to hang onto the planet's surface, despite it having just 38 percent of the gravity we enjoy on Earth. What happens if you want to check out a small moon or an asteroid with a fraction of that gravity? You design a robotic hedgehog, of course.

Stanford University researchers and NASA are working together on spiky space balls that could dance across the surfaces of moons and asteroids whose low gravity and rough surfaces would bog down a regular rover. … Read more

Stick these solar cells on your phone or whatever else

What if everything around you had the potential to generate small amounts of energy?

We've seen flexible, even stick-on photovoltaic cells before, but these decal-style solars are compact and fun.

In a recent article in Scientific Reports, Stanford University mechanical engineering assistant professor Xiaolin Zheng and colleagues describe thin-film solar cells that can be peeled and stuck anywhere.

The researchers manufactured them on a reusable silicon and silicon dioxide wafer and then stuck them on paper, plastic, and window glass.

The original cell efficiency of 7.5 percent was maintained, and the manufacturing uses existing processes and materials. That … Read more

Latest camera-trapping tech helps capture more animals

Since the late 1800s, researchers and the curious have been trying to use photography to capture images of animals in the wild. Over the decades, the technology behind these camera traps has gone from trip-wire film cameras to sophisticated digital rigs. And these days, with the accessibility of digital video, the footage being collected is absolutely arresting. Check out the World Wildlife Fund or the Wildlife Conservation Society to see some of their videos of tigers, gorillas, and rhinos in their natural habitats.

Closer to home, we caught up with a technology specialist who works at Jasper Ridge, Stanford University'… Read more

Facebook hackathon shows off the Zuckerbergs of tomorrow

There's a "Battle of the Bay" going on tonight at Facebook's Menlo Park, Calif., headquarters, and it's happening in a haze of Chinese food, juggling, music, and coding. And maybe some unicycling, if you're lucky.

The social network holds its second Stanford versus Cal (University of California at Berkeley) hackathon for budding coders to try their hands at creating new products. Nearly 200 students from both campuses sat in front of their laptops at around 5 p.m. with no intention of stopping until 3 p.m. tomorrow. That's what Facebook hackathons are … Read more

Electric vehicle concepts hint at a three-wheeled future

Convincing a nation so steeped in its car culture to think differently about the way we drive is a test of both patience and persistence. But the 2012 Vehicle Concept Showcase at Stanford University's Center for Automotive Research yesterday offered some interesting arguments about how our future personal transportation will better suit our needs.

One feature that may take some adjustment for many drivers is wheel configuration. Only two of the eight vehicle concepts rolled out at the showcase had the tried and true four-wheel configuration -- most were three-wheelers. As the makers of Switch Vehicles pointed out, dropping … Read more

'Cool' gadgets shine at Stanford

STANFORD, Calif. -- One of the tricks of building a successful company is identifying new markets. So while you might never have known you wanted a digital scent delivery system, a startup called Scent Sciences thinks that's exactly what you desire.

Scent Sciences and dozens of other companies flocked to Stanford University yesterday for the annual Cool Product Expo, a showcase of some of the, well, coolest gadgets, toys, electric cars, and oddball beauty items around. Among the most interesting items on display were 3D Systems' Cube, a personal 3D printer that costs just $1,300 and is being … Read more

Researchers mod computer to copycat human motions

Webcams and video-conferencing software like Skype have really enhanced the way we communicate with friends, family, and colleagues around the world. Even so, talking to a floating head on a computer screen can still feel pretty cold, and it doesn't look like we're going to get a teleportation device any time soon (le sigh). However, researchers at Stanford University are hoping to make that interaction a little more lifelike with a computer that can mimic human motions.

David Sirkin and Wendy Ju from Stanford's Center for Design Research created a motorized flat-screen display that copycats various human motions like shrugging, nodding, and laughing. The team did so by adding motors to the Apple iMac G4 and then linking it to software that reads a person's movements and instructs the G4's moveable arm to perform one of nine motions. … Read more

Virtual reality comes to life at Stanford lab (video)

What does it feel like to chop down a tree? Or walk a narrow plank suspended above a deep pit? Stanford University's Virtual Human Interaction Lab can take you there.

Professor Jeremy Bailenson has created a thoroughly convincing virtual-reality environment at the Stanford lab. But what makes it feel so real? The lab uses technology to provide sensory feedback in a couple of different ways. There are devices called "butt-kickers" under the floor that make it shake, 22 speakers provide audio input, and, lastly, there's the head-mounted display that offers a stereoscopic view of the virtual … Read more

Stanford University researchers break NuCaptcha video security

When it launched in 2010, NuCaptcha touted its proprietary technology as being able to "provide the highest level of security available" by using video streams to display those distorted letters you type in to prove you're really a human.

Now, however, the company's claims of providing "the next generation of Captcha security" look a tad optimistic.

A team of Stanford University researchers said today that they discovered a way to break the security of a recent version of NuCaptcha's video Captcha by borrowing concepts from the field of machine vision, which developed techniques … Read more

Stanford pioneering a wireless electric highway

Stanford researches may have solved the problem of range anxiety by wireless charging technology that could one day create an electric highway.

Wireless recharging already is used by some electric vehicle charging stations to fill up batteries without cords or plugging into an outlet. MIT helped pioneer this technology and spun it off into a wireless charging startup, WiTricity. However, Stanford researchers improved on this concept and devised a way to transmit 10 kilowatts of electric power across a 6.5-foot distance with minimal energy loss. By overcoming transmitting electricity across a significant distance, researchers will make it possible to … Read more
