As development of micro- and nano-scale devices continues to advance, so does the need for an equally-tiny method of powering them. There’s not much point in developing a surveillance micro air vehicle the size of a housefly, for instance, if it requires a watch battery in order to fly. That’s why DARPA is funding a project to create really tiny batteries. Just how tiny are we talking, here? Well, they’re aiming for something smaller than a grain of salt.  Read More

Not so long ago, the idea that a car could drive itself seemed mildly insane, but thanks to the impetus provided by the DARPA Urban Grand Challenge and ongoing research around the globe, driving might become a hobby rather than a necessity much sooner than you think. One of the pioneers in the field, the Berlin-based AutoNOMOS group unveiled its latest project earlier this year. Known as FU-X "Made in Germany" the tech-laden VW Passat uses GPS, video cameras, on-board laser scanners and radars to navigate autonomously, giving it the potential to be used as a driverless taxi cab. Its latest trick – you can now hail it with an iPad.  Read More

The widespread usage of exoskeletal robotics to augment human beings moved a step closer this week when Raytheon demonstrated its second generation Exoskeleton, the XOS 2. The new robotic suit (think of it as wearable robot guided by a human brain) is lighter, faster and stronger than the original proof-of-concept XOS 1, yet uses half the power. While Raytheon's development is primarily focused on military usage, exoskeletons for the mobility-impaired are already at market and industrial exoskeletons from Japan, Korea and Isreal are not far behind. One day in the not too distant future, one of these suits will enable us all to have superhuman strength, speed and endurance.  Read More

The U.S. Defense Advanced Research Projects Agency’s (DARPA) Vulture program, which aims to develop and demonstrate technology to enable a single high-altitude unmanned airplane (UAV) to operate continuously for a period of five years, has entered phase II. Under the terms of an US$89 million contract, Boeing will develop a full-scale demonstrator called the SolarEagle that will make its first demonstration flight in 2014. The aircraft will have highly efficient electric motors and propellers and a high-aspect-ratio, 400-foot wing for increased solar power and aerodynamic performance.  Read More

Researchers at the University of Michigan are developing laser systems for protecting military helicopters from heat-seeking missiles. The lasers wouldn’t shoot down the missiles, but would instead jam their sensors, essentially blinding them. This isn’t the first time that laser systems have been used for this purpose, but the creators of this system claim that it is better suited to helicopters than anything that has come before.  Read More

In April scientists at the U.S. Defense Advanced Research Projects Agency (DARPA) put out a call seeking designs for a tactical flying car under its Transformer (TX) program. One of the first to respond is AVX Aircraft Company – its AVX Aircraft that can be manually driven on the ground like an SUV and also boasts Vertical Takeoff and Landing (VTOL) capability.  Read More

Having placed third in the prestigious DARPA Urban Challenge in 2007, engineering students from Virginia Tech have returned to the forefront of autonomous vehicle development by designing and building four GUSS (Ground Unmanned Support Surrogate) vehicles. Able to carry 1800 lbs and designed to resupply and evacuate troops in the field as well as reduce the load carried by them, the vehicles are due to make their debut at the impending 2010 Rim of the Pacific (RIMPAC)war games in Hawaii.  Read More

Not so long ago it seemed that the golden age of giant lumbering airships had gone down with the Hindenberg, consigned to less spectacular roles in research, advertising and as a great camera platform above sporting events... but they're making a comeback. Lighter-than-air aircraft are returning to passenger carrying roles in tourism and in recent years we've seen a new-generation of airships put forward as a cargo-lifting solution (DARPA's Walrus Project) and even as a corporate air yacht (Aeroscraft ML866). Now the U.S. Army is moving quickly to build a hybrid airship weapons system that will act as a long-duration UAV – a very big UAV. The Long Endurance Multi-Intelligence Vehicle (LEMV) will be longer than a football field and stay aloft at altitudes of 20,000 feet for more than three weeks at a time providing an "unblinking eye" for surveillance and reconnaissance.  Read More

Boeing's X-51 WaveRider has made aviation history by completing the longest ever supersonic combustion ramjet-powered flight. The unmanned aerial vehicle (UAV) flew for almost three and a half minutes in the skies off the southern California coast on Wednesday, reaching an altitude of about 70,000 feet and hitting hypersonic (Mach 5) speeds.  Read More
