The people have spoken and the machines are immortalized.

More than 17,000 humans voted online for the 2012 inductees to the Robot Hall of Fame, and they chose a mixture of friendly and terrifying bots, depending on your perspective.

Come on down, Wall-E, BigDog, Nao, and PackBot. You've earned a place among the stars.

Although the 12 nominees were selected by robotics experts, it was the first time that popular votes chose the inductees to Carnegie Mellon University's hall of immortal robots. … Read more

There are 110 million active landmines strewn across 64 countries around the world, according to the United Nations, leading to thousands of people being killed or maimed every year. Huge stretches of land are danger zones. Clearing those areas is a hazardous and delicate operation that puts people at great risk.

Afghanistan-born designer Massoud Hassani has come up with an unusual minesweeper that uses the wind to propel itself in a search for landmines. The Mine Kafon is made from bamboo and biodegradable plastics. The plastic feet push against the ground, triggering landmines with pressure.… Read more

I've become a bit of a worrier of late.

Not because I worry about the coming election, Windows 8, or things that seem to move in my fridge.

No, it's the idea that with man proving he can leap in from outer space, outer-spaceans might try to do the same.

I am sure that our government will want to reassure us. I know that President Obama has told NASA to call him the minute aliens land.

But how can we possibly defend against outerworld beings? We don't seem terribly good at defeating inter-world ones.

Thankfully, I bring … Read more

If MacGyver were trapped behind a jammed door in a burning room, he would use his shirt to filter the smoke, then craft an explosive from a paperclip and strand of hair to blow that baby open.

If today's most sophisticated robot found itself in the same conundrum, it would likely be unable to follow the famed secret agent's resourceful example. A team of Georgia Institute of Technology researchers hopes to change that.

They're working to equip machines to use objects in their path for high-level tasks, particularly those involved in tedious military operations. Robots are forging an increasing presence in military and civilian missions, with the U.S. military actively challenging roboticists to design robots for disaster relief.

"This project is challenging because there is a critical difference between moving objects out of the way and using objects to make a way," Mike Stilman, a Georgia Tech professor of robotics who's leading the research team, said in a statement. "Researchers in the robot motion planning field have traditionally used computerized vision systems to locate objects in a cluttered environment to plan collision-free paths, but these systems have not provided any information about the objects' functions." … Read more

Let the human-hunting games begin. Boston Dynamics has a new video of its oversized beast pursuing defenseless human meatsacks through a forest.

The Legged Squad Support System (LS3), aka AlphaDog, is designed to carry 400 pounds of payload and travel 20 miles without refueling. It's funded by DARPA and the U.S. Marine Corps and is meant to support troops in rugged terrain.

The latest video shows the cow-size monster clambering over rocks and up steep hillsides with heavy weights on its sides. It charges through bushes without a thought. … Read more

Run, don't walk, if you want to get away from this cheetah robot. If you happen to be non-human, you might stand a chance of surviving.

That's because Boston Dynamics' quadruped has set a new speed record and can now outrun the world's fastest human, Usain Bolt.

The DARPA-funded cyber-cat, already the fastest legged robot around, can sprint 28.3 mph, better than Bolt's best 20-meter split of 27.78 mph, the company said, quoting data from the International Association of Athletics Federations. The robot can now run significantly faster than its former top speed of 18 mph because engineers increased its power and refined the leg control algorithms. … Read more

Powerful explosives from fires or roadside bombs produce two near-simultaneous blasts: first, a high-pressure blast that can cause internal injuries, and then a thermal blast that produces temps above 1,000 degrees Fahrenheit and can literally cook skin, according to Robert Lochhead, a professor of polymer science at the University of Southern Mississippi.

He worked with chemists to engineer a high-tech camouflage paint that is waterproof; easy to apply and remove; non-irritating to the eyes, nose, and mouth; and actually reflects -- instead of absorbs, like most face paints -- intense heat.… Read more

In addition to slithering, crawling, and flying just about anywhere, what if robots could camouflage themselves? This tentacled prototype can be made to look like -- or stand out from -- its background with a simple injection of dyes.

Developed by engineers at Harvard University's Whitesides Research Group, the "soft machine" silicone quadruped crawls along on pressurized gases fed through an umbilical cord.

Users can send different dyes through channels in the robot's body, allowing it to blend in or stand out in startling fashion, such as glowing in the dark. Color changes take about 30 seconds, but don't require further power to sustain the disguise. … Read more

When the going gets tough, the Defense Advanced Research Projects Agency creates a vehicle -- capable of driving on water, land, and even deep mud -- to keep things going.

Officially known as the captive air amphibious transporter (CAAT), this water wagon currently under development looks like the strange lovechild of a tank and a hovercraft. CAAT could one day serve as an invaluable tool for the U.S. military when it delivers supplies to the coasts of disaster-stricken areas. … Read more
