Cheetah-Cub robot learns to walk from the animals

We know Boston Dynamics is keen on four-legged robots, even creating a cheetah of its very own. So is the Ecole Polytechnique Federale de Lausanne in Switzerland; its Cheetah-Cub has been in development at the Biorobotics Laboratory since 2008.

Teaching a quadruped robot to walk can be a tricky business, though. Something called a Central Pattern Generator (CPG) network is used to generate movements according to a repetitive pattern. But no matter how robust the rhythm of the movements is, it can be tough to implement outside of a lab environment, where the ground won't necessarily always be even.

Enter the Italian Institute of Technology (IIT). The team there broke down the movements of horses via motion capture into what it calls "kinematic Motion Primitives" (kMP), analyses of the trajectories of limbs and bodies, translated into data that can be fed into a CPG. … Read more

Canon 5D Mark III gets clean HDMI firmware update

First announced in October 2012, version 1.2.1 of the Canon EOS 5D Mark III firmware will allow users to output a clean HDMI feed. One of the key disadvantages up until now for the Mark III has been the extra information that is output alongside the Live View image when using HDMI out, which made the footage unusable for actual recording purposes.

The update allows users to record uncompressed (YCbCr 4:2:2, 8 bit) video to an external recorder or display it on an external monitor during filming. This puts the Mark III in line with several … Read more

Lab-quality microscope now mounts onto most Apple iOS devices

To my fellow geeks who've long dreamed of having a lab-quality digital microscope that mounts to your phone, the time has come.

Oregon-based optics manufacturer Bodelin will begin shipping its brand-new ProScope Micro Mobile on May 1. One version fits the iPhone 4, 4s, 5, and iPod Touch; another the iPad; and another the iPad Mini. Whatever size, it will set you back $149.… Read more

Glowing plants could act as biological night lights

Humans have a lot in common with magpies. We gravitate toward shiny things.

It's easy, then, to see why the Glowing Plants project on Kickstarter has more than doubled its goal and still has 38 days to go. It's a fascinating mix of botany, science, and unexpected glowing things.

Some people can boast a green thumb, but very few people can boast a glowing green thumb. For a pledge of $40, Glowing Plants will send you 50 to 100 seeds to let you raise your own glowing plant at home. The project's creators say that this is a one-off opportunity and the seeds will not be available commercially later on.… Read more

SpaceShipTwo fires rocket engine in supersonic flight

If you've got $200,000 to spend on a ticket to suborbital space, your spaceship is nearly ready.

Virgin Galactic's SpaceShipTwo, billed as the world's first commercial space plane, notched an important milestone today by firing its rocket engine during flight for the first time.

The test at Mojave Air and Space Port in California saw the passenger space plane detach from its dual-hull mothership, WhiteKnightTwo, at an altitude of 47,000 feet while being piloted by Mark Stucky and Mike Alsbury of builder Scaled Composites.

The pair then ignited the rocket motor, which propelled the craft up to 55,000 feet. During the 16-second engine burn, SpaceShipTwo went supersonic, hitting Mach 1.2. … Read more

Nest software update aims for more comfort, lower bills

With all of the 10 hottest years on record having come since 1998, it's hard to deny that things are getting hotter. And as the temperature rises, so too does society's power usage.

With that in mind, Nest, the maker of the Learning Thermostat, has just issued its latest software update aimed at increasing people's comfort, while at the same time reducing their energy bills.

Last week, the company unveiled Nest Energy Services, a set of initiatives available to customers of certain utility companies that has a similar goal. But the new software update works for anyone … Read more

NASA cycles through another Great Moonbuggy Race

It may be more than 40 years since NASA last put a man on the moon, but those Apollo missions continue to serve as a driving force for some aspiring engineers.

On Friday and Saturday, the space agency hosted its 20th annual Great Moonbuggy Race. For these competitions, entrants from colleges and high schools have to to design, build, and race lightweight, human-powered vehicles -- think pedicabs on steroids -- that a pair of riders then must muscle over a half-mile course designed to simulate the lunar surface. NASA says that the "race teams face many of the same … Read more

NASA's Kepler telescope and the quest for life out there

(CBS News) The question "Is anybody out there?" grows more tantalizing with the discovery of each new far-off planet. Barry Petersen has been talking to scientists searching for clues...

Starry nights inspire wonder, and wondering: Is there life out there?

So how fitting that, in March 2009, NASA launched the planet-hunting telescope Kepler into the night sky.

Look up tonight at the constellation Cygnus -- also known as the Northern Cross -- and up in that one slice of sky is where Kepler has been scanning 150,000 stars every 30 minutes for the last four years.

Coming soon: A Breathalyzer for pot and cocaine?

Some people drive high.

They shouldn't, but they're high, so they don't really know what's good for them and what isn't.

Should they get stopped by police, the long nose of the law can sometimes sniff the presence of marijuana in their car.

Should they happen to have nosed their way into some cocaine, there might be traces of white powder around their nostrils.

As yet, though, there hasn't been a machine that can detect the presence of such drugs on one's breath, as there is for alcohol.

Scientists in Sweden, however, believe they have made some progress in creating such a device.… Read more

At Shapeways facility, order emerges from 3D-printed chaos

NEW YORK -- Looking at the diagram in front of me, which shows a pile of random things jumbled together, I can't help but think that I'm looking at the aftermath of something like a hurricane or a flood.

Actually, however, this is optimized organization of the highest order. It's a chart showing the dozens of item that will emerge in a little while from the 3D printer I'm standing next to.

Here at the Shapeways production facility in Queens, nine high-end 3D printers chug along continuously, churning out hundreds, or even thousands, of individual products … Read more
