While any soldier dreads the idea of being shot, sustaining an internal abdominal injury from an explosion or other impact can be far worse. Bleeding from wounds that can't be compressed causes some 85 percent of preventible battlefield deaths.

As part of DARPA's Wound Stasis program, Arsenal Medical has developed an injectable polymer foam that expands inside the body to stanch internal bleeding.

The concept of foam growing in the body reminds me of that 1980s B-horror film "The Stuff," but apparently it's effective.

Based on testing in pigs, DARPA says the product can control hemorrhaging in an abdominal cavity for at least an hour, a critical window to get the soldier to a medical facility. … Read more

You gotta hand it to the marketers who come up with robot acronyms. Can it get any better than Extreme Access System for Entry (EASE)?

Sounds innocuous enough, right? Until this little critter tries to float into your room to spy on you. It's one of two bots unveiled by CyPhy Works, headed by iRobot co-founder Helen Greiner.

EASE and PARC (that's Persistent Aerial Reconnaissance & Communication), a communications relay, are compact flying machines that can fly between 3 feet and 1,000 feet while remaining tethered to their human controllers via microfilaments. … Read more

We've seen several designs for military exoskeletons that can boost soldier strength, but these leg braces from Canada's Bionic Power generate electricity on the go.

The PowerWalk system looks like an athletic knee brace and weighs about 1.7 pounds. The braces generate about 12 watts of electricity when the user walks at a normal pace; an hour's walk can apparently produce enough juice to recharge four cell phones.

That's especially handy for soldiers who have to carry up to 28 pounds of batteries on a 72-hour mission to power everything from flashlights to night vision goggles, according to Bionic Power. … Read more

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
