Under our "A Mechanically Based Antenna" (AMEBA) program, researchers are exploring aspects of electromagnetic physics that might allow the expansion of wireless communication and data transfer into undersea, underground, and other settings where such capabilities have been absent. In a paper recently published in Nature Communications, a team of researchers led by the Department of Energy's SLAC National Accelerator Laboratory reported on their recent progress. SLAC, in collaboration with researchers from SRI International and photonics tech firm Gooch and Housego, developed a new type of pocket-sized antenna that emits very-low frequency (VLF) radiation with wavelengths of tens to hundreds of miles. These waves travel very long distances and can penetrate environments that would block radio waves with shorter wavelengths. While today's most powerful VLF technology requires gigantic emitters, the SLAC-developed antenna is only four inches tall, so it could potentially be used for tasks that demand high mobility, including communications during rescue and defense missions.

What do you get when you put robots, unmanned aerial systems, and a bunch of engineers together in a mine? That's not a trick question. The answer is the DARPA Subterranean Challenge STIX integration event. STIX brings together the competing teams to test out their systems in an environment representative of a challenge course. The testing this week is being held at the Colorado School of Mines' Edgar Experimental Mine. And, to be clear, the engineers stay outside the mine.

Tonight our R3D2 payload successfully caught a ride to space aboard @RocketLabUSA's Electron rocket! The payload is our Radio Frequency Risk Reduction Deployment Demonstration (R3D2), a new type of membrane reflectarray antenna that we're aiming to space qualify. The antenna, made of a tissue-thin Kapton membrane, was packed tightly for stowage during launch. In a few days, it will deploy to its full size of 2.25 meters in diameter while in low Earth orbit. @NorthropGrumman is the prime contractor and integrated the 150 kg satellite; MMA Design designed and built the antenna. Trident Systems designed and built R3D2's software-defined radio, while Blue Canyon Technologies provided the spacecraft bus.

Researchers from @USCViterbi supporting DARPA's Lifelong Learning Machines program created an AI-controlled robotic limb driven by animal-like tendons and capable of teaching itself a walking task. A bio-inspired algorithm allowed the robot to complete a walking task on its own after only five minutes of "unstructured play" in which it conducted random movements that enabled the robot to learn its own structure as well as that of its surrounding environment. The robot's ability to learn by doing is a significant advancement towards lifelong learning in machines. The current machine learning approaches rely on pre-programming a system for all potential scenarios, which is complex, labor intensive, and inefficient. What the USC researchers accomplished shows that it is possible for AI systems to learn from relevant experience -- finding and adapting solutions to challenges overtime.

darpa's Media: New research from @columbia’s School of Engineering and Applied Science, and funded by DARPA's Life

New research from @columbia’s School of Engineering and Applied Science, and funded by DARPA's Lifelong Learning Machines (L2M) program, empowered a robot to learn what it is, from scratch, with no prior knowledge of physics, geometry, or motor dynamics. The robot was able to build a self-simulation following a brief period of "babbling," as the researchers described it, and extensive computation. According to Columbia, the robot can then use that self-simulation internally to contemplate and adapt to different situations, and handle new tasks. In this image, the robot is performing a writing task. It was able to do so using the same self-model it built originally to complete a different task in which it picked up objects and placed them in a container. The L2M program is pursuing new AI architectures and machine learning techniques to support machines that can apply prior skills and knowledge to new situations, without forgetting previous learning. Currently, specifically programmed and trained systems cannot adapt to changing circumstances, making them unpredictable and potentially unsafe to operate in dynamic conditions. That challenge limits the application of AI systems in military contexts. The research is described in a news story on the school's website: https://engineering.columbia.edu/press-releases/lipson-self-aware-machines.

This handsome creature - the #tardigrade- only looks like something that should be floating down a parade route. In fact, the tardigrade is a master survivor, able to withstand environmental extremes thanks to protective proteins. As part of DARPA's Biostasis program, a research team led by @harvardmed is studying how tardigrade proteins work and how that knowledge could be applied to halting tissue damage and preventing cell death in humans following injury or illness. According to HMS, "The team's goal is to engineer an optimized version of these proteins and use them to slow down metabolic activity in injured cells - the biological equivalent of hitting the pause button on cellular processes, including damage-causing inflammation, infection and, ultimately, cell demise. The team's ultimate goal is to develop a protein-based therapy that can halt tissue damage in traumatic injuries, heart attacks, strokes and sepsis, among other conditions."

DARPA's Radio Frequency Risk Reduction Deployment Demonstration (R3D2) is set for launch in late February on a @RocketLabUSA Electron rocket from the company's launch complex on the Mahia Peninsula of #NewZealand. The goal is to space-qualify a new type of membrane reflectarray #antenna. The antenna, made of a tissue-thin Kapton membrane, packs tightly for stowage during launch and then will deploy to its full size of 2.25 meters in diameter once it reaches low-Earth orbit (LEO). R3D2 will monitor the dynamics of antenna deployment, survivability, and the radio frequency (RF) characteristics of a membrane antenna in LEO. A successful demonstration will help prove out a smaller, faster-to-launch, lower-cost capability, allowing the Department of Defense and other users to make the most of the new commercial market for small, inexpensive launch vehicles. Satellite design, development, and launch took approximately 18 months. Rocket Lab plans to host a webcast and live stream the launch from its website. #satellite #spacelaunch #military #engineering #origami #space

Things are heating up in our Subterranean Challenge! Nine teams have qualified to take part in the SubT Integration Exercise, known as STIX, this April at the Edgar Experimental Mine in Idaho Springs, Colorado. The exercise provides an opportunity for them to try out their technologies, including robotics, sensors, and communications solutions, in a representative environment prior to the Circuits Stage of the SubT Challenge later this year. We have not yet announced the location of the Circuits Stage competition. The overall SubT Challenge pushes teams to develop and integrate technologies that rapidly and remotely map, navigate, and search subterranean environments including natural cave systems, human-made tunnels, and urban underground settings -- spaces that are too dangerous, dark, deep, and unknown to risk human lives. Shown here is the entrance to the Edgar Mine, run by @coloradoschoolofmines. #SubTChallenge #military #subterranean #cave #explore #robotics #subway #tunnel #navigation

darpa's Media: Can understanding the highly integrated sensory and nervous systems of miniature insects help engin

Can understanding the highly integrated sensory and nervous systems of miniature insects help engineers develop smaller, lighter, more power-efficient artificial intelligence systems? DARPA's latest AI Exploration Opportunity, called μBRAIN (short for Microscale Bio-mimetic Robust Artificial Intelligence Networks), aims to find out. μBRAIN invites proposers to submit innovative basic research concepts aimed at emulating insects' impressive function in prototype computational models that can be mapped onto suitable hardware. Nature has forced on small insects drastic miniaturization and energy efficiency, some having only a few hundred neurons in a compact form-factor, while maintaining basic functionality. The primary goal of the μBRAIN effort is to understand the computational principles, architecture, and neuronal details of small bio-systems driven by extreme size, weight, and power needs in nature. Studying miniaturized insects may reveal fundamental innovations in architecture and computation analogous to their simultaneous simplicity, efficiency, and complex functionality. Compared with larger-brained organisms, these insects may hold the keys to strategies for AI that combine operational efficiencies in the use of energy, time, and space. DARPA aims to identify new computing paradigms that will enable improved AI with considerably reduced training times and power consumption.

darpa's Media: Our Materials Architectures and Characterization for Hypersonics (MACH) program seeks new materials

Our Materials Architectures and Characterization for Hypersonics (MACH) program seeks new materials and designs for cooling the hot leading edges of hypersonic vehicles traveling more than five times the speed of sound. At those incredibly high speeds, hypersonic vehicles experience intense friction with the surrounding air. According to program manager Bill Carter, "The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we've seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance." The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems. This image shows an artist's concept of what a hypersonic vehicle in flight might look like. #military #techgeek #aviation #aviationlovers #technology #avgeek #aircraft #hypersonics #materialsscience #engineering #manufacturing #materials #flight #computationaldesign #airforce

What does a competition among radios look like? And why should you care? The picture answers the first question. As for the second, RF spectrum is essential to communications and connectivity, but we live in a spectrum-limited world. As more and more wireless, connected devices come online -- think smartphones, speakers, watches, fitness trackers, cameras, etc. --- the demand for spectrum spikes. For the past century, regulators have allocated static chunks of spectrum to a relatively small group of broadcasters and service providers, as well as government and military users, and these organizations have to work within their defined spaces. As demand increases, however, society needs to make better use of all available spectrum by dynamically shuffling traffic. DARPA is exploring autonomous, software-defined radio technology that uses artificial intelligence to deconflict wireless traffic and help optimize spectrum usage. Our Spectrum Collaboration Challenge (SC2) is pushing teams to refine that technology. Last week, during the second preliminary event before the SC2 finale in 2019, teams gathered at Johns Hopkins University's Applied Physics Laboratory to see how their radios performed when tested in different fictional scenarios, such as enabling communications by firefighters and air crew responding to a wildfire. All fifteen teams are now eligible to participate in the finale, which will occur at Mobile World Congress Americas 2019 in Los Angeles.

The scientists and engineers we fund @usnistgov are experts at building atomic clocks. Their newest ytterbium optical lattice clocks have set performance records for stability, reproducibility, and minimizing systematic uncertainty. Owing to their extreme performance, the clocks are useful tools for taking hard-to-conduct measurements. For instance, differences in the clocks' readouts would suggest an external factor is at play, which means the clocks could be very useful for measuring gravity.
