Engineer stashed Navy drone trade secrets in his personal Dropbox
Trade secret theft allegations are serious enough in the corporate world, but they're particularly grave when they involve military projects. And one contractor is learning that the hard way. A Connecticut federal court has found electrical engineer Jared Sparks guilty of six trade secret theft and transmission charges after he took files relating to underwater drones built for the US Navy's Office of Naval Research. When contemplating a switch of jobs from drone builder LBI to its software partner Charles River Analytics, he uploaded "thousands" of his then-current employer's sensitive files to his personal Dropbox account, including accounting and engineering data as well as design-related photos and renders.

MIT teaches self-driving cars to change lanes like real drivers
Autonomous vehicles really don't know how to switch lanes as well as people do. They tend to rely on either relatively static data models that are difficult to study in the thick of traffic, or are basic enough that the car might only change lanes when it's absolutely necessary -- that is, hardly at all. MIT's CSAIL has a better way. The school has developed an algorithm that changes lanes more like humans do while respecting road safety.

Robots could soon cooperate on surveillance
Computers are getting better at spotting objects, but they tend to work in isolation. What good would a security robot be if it couldn't share info about an intruder with other machines? Cornell scientists might have an answer. They're designing a system that would let robots and other autonomous devices cooperate with each other on identifying and tracking objects. Each bot would send its imagery to a central unit that could talk to both other camera systems and the internet to help identify objects. The group would combine and compare images to follow objects and collect more information about them, getting more data than they would if they did all the work by themselves.

Smart body armor could gauge brain damage from explosions
Explosions are insidious. Even if a blast doesn't deliver a conspicuous injury, it can inflict brain trauma that might not be evident until much later. The US Navy's Office of Naval Research doesn't want medics to wait, though. It's developing Blast Load Assessment Sense and Test (conveniently, BLAST), a sensor system that could determine whether or not an explosion's shockwave is likely to have injured your brain. Tiny sensors in your helmet and body armor would record the blast pressure and share it with a scanner. When combined with a palm-sized neurological assessment tool (which stimulates your fingers to gauge your responses), the data would let medical teams quickly decide whether or not you're able to fight.

US Navy's drone 'swarmboats' show off pack tactics
While the US Navy's new state-of-the-art USS Zumwalt destroyer struggles to remain functional, the service branch's R&D department has been busy investigating cutting-edge tech at a much smaller scale. Back in October, the Office of Naval Research (OCR) demonstrated the harbor defense capabilities of a group of prototype small autonomous boats, aka "swarmbots," in Chesapeake Bay.

MIT's sensor network tracks your power-hungry appliances
You get a bill from your electricity provider every month laying out how much energy you used, but there's no easy way to get a breakdown of which appliances suck down the most juice. But the US Navy has partnered with MIT scientists to design a cheap, portable sensor network that tracks the power drain of each of your domestic devices.

Gene-modified soil bacteria promise eco-friendly computing
You normally need non-renewable elements or minerals to create nanowires. However, the US Navy's Office of Naval Research may have a better solution: the life living in the dirt under your feet. Its sponsored researchers have crafted nanowires from genetically modified Geobacter, a bacteria you find in soil just about everywhere on Earth. The team altered the bacteria so that it would replace amino acids with tryptophan, which is a much better electrical conductor (2,000 times) at the nanoscopic scale. String enough of those bacteria together and you suddenly have wiring that's virtually invisible to the human eye. They wires are tougher and smaller, too, so they stand a better chance of surviving inside electronics.

Navy researchers make bulletproof glass out of clay
The US Naval Research Laboratory announced a major breakthrough in materials science on Thursday. After decades of research and development, the NRL has created a transparent, bulletproof material that can be molded into virtually any shape. This material, known as Spinel, is made from a synthetic powdered clay that is heated and pressed under vacuum (aka sintered) into transparent sheets. "Spinel is actually a mineral, it's magnesium aluminate," Dr. Jas Sanghera, who leads the research, said in a statement. "The advantage is it's so much tougher, stronger, harder than glass. It provides better protection in more hostile environments -- so it can withstand sand and rain erosion."

Navy enlists UAVs to uncover atmospheric ducts, protect comms
Turbulence. A minor bother for us, but a huge issue for enlisted seamen. So-called "ducts" in the lower atmosphere can wreak all sorts of maritime havoc; trapping radar and causing radio comms to travel further than expected and into the hands of the enemy. The Office of Naval Research's Ocean Battlespace Sensing Department (rad name, right?) isn't satisfied with using balloons to keep track of the ducts anymore, and is deploying drones instead, including Insitu's ScanEagle shown above. The result should be a greater understanding of how atmospheric conditions affect radar and communications, which could ultimately provide a tactical advantage -- at least while we wait on those 100-kilowatt lasers.

Navy awards weaponized railgun manufacturing contract to BAE Systems
Just over 18 months after making its video debut, the Navy's electromagnetic railgun has a manufacturer. BAE Systems -- known for e-ink-powered tank camouflage, autonomous spiderbots and machine-gun-mounted lasers -- won the government contract and hopes to have phase-two prototypes ready "as early as next year." While the current design is capable of firing one shot, the Office of Navy Research hopes for six to ten shots per minute. If that doesn't scare you, consider this: The pulse-driven projectiles travel at Mach 6 and can hit targets over 100 nautical miles away. Don't worry, it's not too late to rethink that career of sailing the high seas as a pirate and get to work on that accounting degree instead.

Giant robot jellyfish reporting for recon duty, sir (video)
As if there weren't enough real jellyfish around to trigger our thalassophobia, researchers at Virginia Tech have created Cryo -- an eight-armed autonomous robot that mimics jelly movement with the help of a flexible silicone hat. The man-sized jellybot altogether dwarfs previous efforts, hence the upgrade from small tank to swimming pool for mock field tests. And unlike the passively propelled bots we've seen recently, Cryo runs on batteries, with the researchers hoping to better replicate the energy-efficient nature of jelly movement to eventually increase Cryo's charge cycle to months instead of hours. That's also the reason these robotic jellyfish are getting bigger -- because the larger they are, the further they can go. Potential uses include ocean monitoring and perhaps clearing oil spills, but the US Navy, which is funding the work, sees an opportunity to recruit jellies for underwater surveillance -- a job the researchers say is suited to their natural-looking disguise. But, before the tables are turned, you can spy on Cryo for yourself in the video below.

US Navy to fund development of vehicle-mounted, drone-shooting lasers
Lasers, particularly those that set boats ablaze and incinerate incoming missiles, have long been on the Navy's mind. Today, the Office of Naval Research revealed its latest energy weapon craving: vehicle-mounted lasers that shoot down drones. Dubbed Ground-Based Air Defense Directed Energy On-The-Move, the project is offering private outfits up to $400,000 each to develop such a system that blasts at full power for 120 seconds and juices back up to 80 percent after a 20 minute charge. The beam is required to pack a punch of at least 25 kilowatts, while the ability to ratchet up to 50 kilowatts is optional. Given that kind of power, Wired points out that making such a solution fit in a Humvee is going to be a feat -- especially when the Navy says it can't weigh more than 2,000 pounds and must fit entirely within a vehicle's cargo area. Have blueprints for a jeep-mountable laser squirreled away in your basement hobby shop? You'll have to send your application in by 2 PM on April 26th to qualify for the federal cash.

Deceptive robots mimic squirrels and birds for potential military use
The military has come up with a multitude of ways to utilize robotics, from bomb disposal and recon bots to Avatar-like surrogates. But a robot that takes its cue from squirrels and African birds to deceive its enemies is decidedly novel territory. Researchers from Georgia Tech, who are also working on a MacGyver bot with AI smarts, are making inroads into developing just such a robotic trickster. The Office of Naval Research is funding the project, which is led by Professor Ronald Arkin. He discovered that squirrels often deceive competing squirrels by visiting fake stash locations while their real acorn collection lies elsewhere, and have developed a robotic model that utilizes the same strategy. The programmed deceptive behavior was successful, as demonstrated in the video after the break. Another lesson from nature is from the African babbler, a species of bird that flocks and crowds around a predator without actually attacking it, with the assumption that it'll back away from the harassing mob. Based on their simulations, the team concluded that deception of this sort is often the right move when pushed against the wall, especially in military operations. "Being honest about the robot's abilities risks capture or destruction," said Arkin. However, he recognizes there is a real ethical quandary when it comes to deceptive robot behavior -- do we really want robots that can lie to us? It's a question that conjures up memories of Battlestar Galactica and brings chills down our spine. Here's hoping we can restrain the robotic deception to the good of mankind.

Marines eye solar energy to eliminate dependency on fuel generators (video)
The United States Marines are already using solar panels to reduce their reliance on fuel generators, but by 2025, the few and proud hope eliminate the diesel-chugging monstrosities entirely. The Office of Naval Research has announced new partnerships with Raytheon, Battelle and Emcore to develop a transportable hybrid system that would leverage solar energy, heat and biofuel to power a Marine outpost for up to 15 days. Not only would these systems run much quieter, but they'd also reduce the need for fuel supply convoys, which are prime targets for attack in battle settings. Currently, researchers are tossing around ideas such as combining a Stirling engine with a satellite-shaped solar concentrator. As is, however, solar concentrators are considered too large for effective transportation. These efforts will take place under Renewable Sustainable Expeditionary Power program, which will keep yearly tabs on the progress of partner companies. To learn more, you'll find an overview video and press release after the break.

Georgia Tech receives $900,000 grant from Office of Naval Research to develop 'MacGyver' robot
Robots come in many flavors. There's the subservient kind, the virtual representative, the odd one with an artistic bent, and even robo-cattle. But, typically, they all hit the same roadblock: they can only do what they are programmed to do. Of course, there are those that posses some AI smarts, too, but Georgia Tech wants to take this to the next level, and build a 'bot that can interact with its environment on the fly. The project hopes to give machines deployed in disaster situations the ability to find objects in their environment for use as tools, such as placing a chair to reach something high, or building bridges from debris. The idea builds on previous work where robots learned to moved objects out of their way, and developing an algorithm that allows them to identify items, and asses its usefulness as a tool. This would be backed up by some programming, to give the droids a basic understanding of rigid body mechanics, and how to construct motion plans. The Office of Navy Research's interest comes from potential future applications, working side-by-side with military personnel out on missions, which along with iRobot 110, forms the early foundations for the cyber army of our childhood imaginations.

MIT's real-time indoor mapping system uses Kinect, lasers to aid rescue workers
We've seen the Kinect put to use to help you find your groceries, but the sensor's image processing capabilities have some more safety-minded applications as well. The fine minds at MIT combined the Kinect with a laser range finder and a laptop to create a real-time mapping rig for firefighters and other rescue workers. The prototype, called SLAM (for Simultaneous Localization and Mapping) received funding from the US Air Force and the Office of Naval Research, and it stands out among other indoor mapping systems for its focus on human (rather than robot) use and its ability to produce maps without the aid of any outside information, thanks to an on-board processor.

US Navy's solid-state laser sets boat ablaze (video)
See that flaming wreckage in the picture above? A laser did that, mounted on board a second vessel similarly bobbing on top of the ocean last week. Yes, even though the United States Navy told us that legitimate seafaring death rays might take another decade to materialize, basic weaponized lasers are ready today, as the 15-kilowatt gun attached to the USS Paul Foster happily demonstrates. Of course, as you'll see in the video after the break, a beam of such minimal power takes a moment to burn through even an unshielded engine and ignite the fuel therein -- once we get some 100+ kilowatt lasers up in there, we shouldn't have such problems.

NAVY SEALs getting fancy LCD sunglasses, will surely show up as DLC in next SOCOM game
We're still a few years away from getting some consumer-friendly LCD sunglasses, but wouldn't you know it the military's already rocking a pair. The Office of Naval Research TechSolutions department has delivered the first 30 sets of what it calls Fast-Tint Protective Eyewear (FTPE). They can change tint automatically based on exterior light, much like currently available prescription glasses, but thanks to their LCD construction can go from dark to clear in just a half-second. This means a SEAL squad could blow a door and infiltrate a room without having to ask the terrorists to hold their fire while everyone takes off their shades. Initial reports are good and SOCOM is planning on buying another 100 sets. Maybe by the time they're delivered someone will release a picture of the things and we won't have to use a random photo of camouflage shades like this one. Update: Travis wrote in with a link to James Vaughan Photography, which has a few photos of prototype versions of these glasses. We've grabbed one. [Image Credit: James Vaughan Photography]

Scientists create sweat-monitoring underwear, break them in (video)
Biochip bracelets be damned -- nanoengineers at UC San Diego want to put sensors in your skivvies. Researchers have begun prototyping a pair of tighty-whiteys coated with the requisite carbon electrodes to make electrochemical computing a reality, as it turns out the nether regions are a prime place to measure chemicals excreted in one's sweat. Until recently, there was some question whether the enzyme sensor solution would handle the stresses of daily life, so to speak, but these briefs were up to the task -- subjected to a torturous gauntlet of bending and stretching, a treated elastic waistband was still able to adequately measure chemicals as required. Funded by the U.S. Office of Naval Research, project leaders envision "smart underwear" that measures a soldier's sweat for warning signs and automatically trigger an appropriate medical dosage. We think they might be getting a wee bit ahead of themselves, though -- we don't yet know how they handle detergent, let alone a quality color-safe bleach. Video after the break, but don't expect any footage of the underpants actually being worn.

New silicon film ferroelectric may pave the way for instant-on computers (or maybe not)
While the gang at Toshiba are still trying to bring FeRAM to the masses, a team of researchers at Cornell University have devised a new ferroelectric material composed of silicon and strontium titanate that they say can be used (someday!) to build "instant on" transistors. And you know what that means -- instant on computers for students, and instant on death rays for future robot armies. To coax the generally mild-mannered strontium titanate into acting "ferro-electrified" (not an actual scientific term), researchers grew it onto a silicon substrate using a process known as epitaxy. The material literally squeezed itself within the spaces of the silicon molecules, which gave it ferroelectric properties. As you may have guessed, this research was partially funded by the Office of Naval Research -- so the "death ray" remark may not be so off base, after all. We'll keep an eye out.[Via Daily Tech]
