FORT HOOD, Texas--Soldiers and civilian contractors braved the heat here this week for the first Robotics Rodeo to view and interact with a long lineup of robot systems and to give feedback on which ones could potentially find a place in the U.S. Army's robo stable.

Despite the hundreds of military robots that show up in concept or as prototypes on company Web sites and corporate reports, humans still do the fighting on the ground and it's likely to stay that way for a while. However, there's a growing niche for "the dirty, the dull, … Read more

Unnamed intelligence agencies and certain academics have yet to give up on data mining to identify terrorists and predict attacks, despite a 352-page tome published last year pronouncing the practice a waste of time.

The U.S. is spending "hundreds of millions of dollars" to develop techniques to mine the mountains of information gleaned from e-mails, telephone calls, interviews with suspects, and now social networks to build-up Facebook-style databanks on international terrorists, according to a recent piece in the British newspaper, The Independent.

The result has been the arrest and interrogation of "many thousands of innocent people&… Read more

DARPA is spending millions of dollars to identify trash cans, which may have raised a few eyebrows, except these and other common urban objects could in the course of today's combat missions prove to be tactically significant.

BAE Systems received a $7.1 million contract to work on Phase II of the Urban Reasoning and Geospatial Exploitation Technology (URGENT) program, which is designed to improve the quality and timeliness of geospatial intelligence U.S. troops receive when facing enemy threats in urban environments.

This phase of the program's goal will be to "develop a 3D reasoning engine … Read more

"We feel your pain" is one of the first messages on the newly inaugurated Chinese Defense Ministry's Web site aimed at assuaging international concern over a spurt in that country's military buildup.

"The aim of the Defense Ministry's Web site is to let the outside world know about China's defense policies...and show off the good image of the military's powerful, cultured and peaceful forces," explains an introductory message.

China's military, the world's largest, has recently increased its spending by almost 18 percent, far outpacing that of its neighbors, … Read more

Civilians recruited by Russian language social networking sites and using Russian Mafia-associated botnets perpetrated many of the cyberattacks on Georgian government Web sites during the five-day Russian-Georgian war in 2008, according to a recent report.

However, while the cyberattackers appear to have had advance notice of the invasion and the benefit of some close cooperation from a state organ, there were no fingerprints directly linking the attacks to the Russian government or military, according to the U.S. Cyber Consequences Unit (US-CCU), an independent nonprofit research institute that produced the report.

Much of the material in the report was already … Read more

Veterans are often reluctant to seek therapy for service-related conditions, but rather than write them off, scientists are creating a virtual online community where servicemembers can find the camaraderie and resources to ease their return to civilian life.

The "Transitional Online Post-deployment Soldier Support in Virtual Worlds" created by the University of Southern California's Institute for Creative Technologies (ICT) will be ensconced within a corner of the virtual landscape of Second Life, a popular online 3D grid where people interact through avatars (PDF).

Also known as Coming Home, this world will contain three main areas: one for … Read more

School bus technology could improve Humvee safety.

BAE Systems has developed a way for crews of up-armored Humvees to quickly remove the ballistic windshield and exit the vehicle during an emergency.

Troops have long complained of being unable to exit tactical vehicles after land mine blasts or during accidents involving water and ditches. The problem is so serious that the 10th Mountain Division invented its own door-ripping tool called the "Rat Claw."

Similar to what's seen in many civilian buses, the BAE VEE Window allows a ballistic windshield to be removed in less than 5 seconds, according … Read more

A robot's potential advantage in autonomy is limited by its need to constantly refuel, but what if the robot could graze its way through a mission, skipping the gas station and foraging for biomass fuel along the way?

The biologically inspired Energetically Autonomous Tactical Robot (EATR) is designed to do just that--find, ingest and extract energy from biomass throughout its operating environment, and switch to conventional or alternative fuels (such as gasoline, diesel, propane and solar) when needed (see PDF).

Robotic Technology of Potomac, Md., and Cyclone Power Technologies of Pompano Beach, Fla., have completed an initial stage in a collaboration that could lead to the world's first grazing robot. The system would obtain energy by "engaging in biologically-inspired, organism-like, energy-harvesting behavior"--in other words, foraging and eating to keep itself going.

It's a tall order. The robot will need to first identify a suitable biomass (wood, grass, paper, etc.) and avoid the indigestible (rocks, metal, or glass).… Read more

Engineers in England have come up with a product to save a few bob for those who work in semi-dangerous occupations--cement body armor.

The vests combine "super strong" cement with recycled carbon fiber, making the vests tough enough to withstand most bullet calibers, according to researchers at the University of Leeds' School of Civil Engineering.

Currently, top-of-the-line bulletproof vests are made with alumina plates--the raw material used to make aluminum--through a costly process called sintering, which involves heating the material for up to two weeks at 1600 degrees Celsius to harden it.

The cement vest, on the other hand, would offer a cost-effective level of protection for people in semi-risky occupations short of full-on combat.

"By using cement instead of alumina we are confident we can deliver a cost-effective level of protection for many people at risk," said research team leader Philip Purnell. "It should be good enough for people like security guards, reporters, and aid workers who are worried about the odd pot shot being taken at them." … Read more
