These super-small drones no longer need a battery

By:

To be a fly on the wall, an observer must be ubiquitous, unobtrusive and quiet. What if, instead, the observer was just a tiny fly-sized robot, independently powered, able to travel like its insect inspiration? That's one possibility from the long line of work on the RoboBee series of miniature flying machines, the latest of which recently flew independently under its own photovoltaic power.

RoboBee is a long-running project of the Harvard Microrobotics Lab and the Wyss Institute for Biologically Inspired Engineering. The end goal is ultimately controlled swarms of insect-sized flying machines, with visions of these swarms performing everything from plant pollination to surveillance. These are ambitious aims, and all have been hindered to this point by a fundamental constraint on the form: the robots are too small to carry batteries.

Much of the flight design uses a tethered power supply, allowing the designers to craft Piezoelectric motors that expand and contract as electrical current passes through the muscle-like membranes. This created wings that could flap and propel the robot upward, but it wasn't until recently that the robot could do it on its own power supply.

RoboBees are smaller than any drone currently employed by the U.S. military, minute enough to make the palm-sized Black Hornet feel gargantuan. Without a sensor payload, it'd be a novelty, but the military has already invested in cheap, expendable sensor-carrying drone gliders for tasks such as meteorological data collection. Should this power supply enable RoboBees to support a meaningful sensor package, they could be used in a similar fashion, scattered as sensors that can flap their way into a new position.

Holding six solar power cells on a stick, and with a second set of wings, the vehicle successfully flew under its own power, even if only for the briefest of moments. The researchers' documentation of their project was published in scientific journal Nature June 26, appearing under the title “Untethered flight of an insect-sized flapping-wing microscale aerial vehicle.”

The whole RoboBee weights 259 milligrams, or less than a paperclip, and under special lights was able to generate enough lift to support an additional payload of 70 mg, which could be used for lightweight sensors, control electronics, or larger power supply in the future. Fitting sensors to a craft the small is likely a challenge, but also essential for the promise of the device.

There is also the small matter that, even using photovoltaic cells, the robot needs an alien sun to fly.

“The Robobee X-Wing needs the power of about three Earth suns to fly, making outdoor flight out of reach for now,” stated the summary from Harvard's School of Engineering and Applied Sciences. “Instead, the researchers simulate that level of sunlight in the lab with halogen lights.”

Should the sensors exist, and the device become capable of outdoor flight, microrobotics could become a ubiquitous part of modern life, performing functions alongside insects and relaying sensor information back as an unseen intelligence platform.

    Coming in 2020: A new technology to link F-35 simulators across the globe

    By: Valerie Insinna ORLANDO, Fla. — Next year, U.S. Air Force F-35 pilots will be able to hop into a simulator and practice large-scale coordinated attacks with other F-35A users in simulators around the globe, Lockheed Martin's head of F-35 training said Tuesday. The capability, called Distributed Mission Training, will allow an unlimited number of F-35 simulators to be networked, enabling high-end training, said Chauncey McIntosh, Lockheed's vice president for F-35 training and logistics. “We've been testing to ensure that it's ready to go with our first customer at Nellis Air Force Base [in Nevada]. We've got hardware that's going up there this month and we're starting our test connections, and everything is looking very well [regarding] this product,” he said during a briefing at the Interservice/Industry, Training, Simulation and Education Conference. “Essentially we're waiting just to get the accreditation from the government. We'll connect that [hardware] and then we'll start running tests on site with software. And then we'll go to our final delivery in spring of 2020," he told Defense News. Currently, F-35 bases can only link as many simulators as they have on site — usually as many as four. However, the Distributed Mission Training capability, or DMT, will allow every U.S. Air Force base to connect up to four of its F-35 simulators with those of every other air base, McIntosh said. At some point, F-35A simulators may also be able to regularly connect with any other aircraft simulator that can be supported on the same network. “Here at Orlando, in our labs, we've already connected to the F-22, the F-16, as well as to [E-3] AWACS [airborne early warning and control aircraft],” McIntosh said. “Almost every week we are writing test scenarios with additional platforms.” Lockheed is under contract to provide DMT to the U.S. Air Force, Navy and Marine Corps, as well as to the United Kingdom. However, because all of those entities run their F-35 simulators aboard different networks, they will be unable to connect with variants from other services, McIntosh said. While Nellis is slated to receive DMT early next year, the F-35 Joint Program Office and Lockheed are still discussing the schedule for further deployments to other bases and services, McIntosh explained. “Our initial efforts are for the Air Force,” he said. https://www.defensenews.com/digital-show-dailies/itsec/2019/12/04/coming-in-2020-a-new-technology-that-will-link-f-35-simulators-across-the-globe

    European Missile Research Paves Way For Collaborative Weaponry

    By Tony Osborne Future conflicts will require weapons that can adapt to different target sets and collaborate to hit harder. As several European nations gear up to begin the development of advanced new combat aircraft, such as the Franco/German/Spanish Future Combat Air System and the British-led Tempest project, and invest in long-range ground-based weaponry, European missile manufacturer MBDA has begun focusing its research programs on delivering these advanced capabilities. The Anglo-French Materials and Components for Missiles Innovation and Technology Partnership (MCM-ITP), led by MBDA and sponsored by the French and UK defense ministries to the tune of €13 million ($14.5 million) a year, has been developing technologies over the last 11 years to help increase the performance and lower the cost of MBDA's British and French weapons. Small to midsize enterprises (SME) and academia have participated in the program, validating technologies with more than 200 projects in eight research domains ranging from rocket propulsion to seekers and fusing, developing them up to a technology readiness level (TRL) of 4. The research program has assisted in development of the French Mica NG air-to-air missile, supporting a small active, electronically scanned array radar module for the seeker of the radar-guided version, while the Spear 3, a network-enabled guided missile being developed in the UK will use a wire-free architecture. In addition, as the Spear 3 family of weapons broadens in the future, it will use an adaptive control system. The ITP is beginning to look at technologies that can speed up the engagement chain, adapt warheads for different kinds of targets and even develop lower-cost air-breathing engines for new families of so-called remote carriers—the attritable unmanned air systems that will support future combat aircraft into theater. “We know that collaborative weapons would be a big advantage to defeat air defenses, but how we do that has not yet been quantified,” says Olivier Lucas, MBDA's director of Future Systems, speaking to Aviation Week at the MCM-ITP Conference in Birmingham, England, on Oct. 15. “We need to demonstrate the benefits you can get from these networked weapons through operational analysis,” he adds. To make collaborative weapons work, Lucas says there will need to be developments in low-cost data links to connect them, and then algorithms that can take advantage of the cooperation and ensure all these systems can still work together in environments where navigation and communication signals could be degraded. Industry has already proved it can make UAVs collaborate and swarm in formations, but as Lucas points out, this is usually done with the aid of satellite-based global positioning systems. The military is unlikely to enjoy such a luxury in a high-end conflict. All four global navigation satellite systems (GNSS)—the U.S. Global Positioning System (GPS), Europe's Galileo, Russia's Glonass and China's BeiDou—work around similar frequencies and could be easily jammed. Weapons such as cruise missiles can already operate without GNSS by relying on inertial navigation systems (INS), or if flying over land they can recognize landscapes based on internal terrain databases. But what if a considerable part of their flight is over water, where there are no landmarks? As part of the MCM-ITP, a team from MBDA, Airbus Defense and Space and French aerospace research agency ONERA have developed a means of correcting INS drift using satellite communication signals. The Resilient and Autonomous Satcom Navigation (Reason) system gives the weapon an alternative measurement signal. Many military communication satellites already have the capability of geolocating interference. Using the signals to provide navigation updates employs a reverse of that process, say engineers. They have already proved the theory by linking an INS fitted to a 4 X 4 vehicle that took signals from two of the UK's SkyNet communication satellites and compared the INS track with that of GPS, noting small deviations from course. The team believes the Reason technology will be valuable for future generations of long-range cruise missiles and anti-ship missiles such as the Anglo-French Future Cruise/Anti-Ship Weapon, currently in a concept phase. Another MCM-ITP project is looking at using artificial intelligence (AI) and a process called deep reinforcement, learning to better understand the levels of autonomy that might be needed in the engagement chain. The Human Machine Teaming (HUMAT) project considers the growing complexity and capability of modern missiles and the increasing amounts of data being collected by multilayered intelligence systems. It recognizes that human operators may need to be supported in their analysis and prioritization of threats by artificial intelligence. The two year-long program, started in November 2017, has studied different elements of the engagement chain, as well as the ethical, legal and technological constraints, with the aim of creating “robust engagement decision-making,” and “effective transfer of task responsibilities between the human operator and the machine.” The HUMAT system has benefits for the weapon command-and-control systems, particularly air-to-surface attack, but also multilayered air defense systems, say MBDA engineers. “We have to understand the information we will share with the weapons, what will be split, what is planned and what decisions are left to the group of weapons,” says Lucas. “This process has to be tuned, you can either program the trajectory of each weapon or tell the weapons: ‘Here are your targets, now do your best,'” he says. Collaborative weapons will also need to feature additional low-cost sensors to help them make their targeting decisions, including those that understand radar signal and resolution, so that the most appropriate weapon can be selected to hit a particular target successfully. Mission planning is also being addressed. MBDA engineers and academics from Queen Mary University of London have been exploring the use of deep-learning techniques to speed up the targeting process for weapons such as cruise missiles. Current air-launched cruise missiles such as MBDA's Storm Shadow/SCALP family use an imaging infrared sensor and autonomous target recognition system in the terminal phase of flight. But to recognize the target, a 3D model needs to be developed as part of the mission planning process. This process can be laborious and time-consuming, so engineers have been studying ways to create the models using satellite imagery. Using deep-learning techniques, the system has been fed thousands of daylight and infrared satellite images taken in different conditions at different times of the day. The Fast Targeting algorithms have learned how to match images with the target area despite various geometric and radiometric distortions, allowing a 3D model of the target to be built much faster. The idea is to make such weapons much more flexible and pave the way for them to be used against time-sensitive targets. Lucas says such technologies will help address the issues associated with combat mass, dealing with the challenge of fewer platforms, so the same weapons will have to be adaptable for different missions and targets. “In recent conflicts in Libya and Syria, weapons could not be used to their full effectiveness, because they were too powerful, and there was a risk of collateral damage,” says Lucas. Operators will be able to program future weapons to scale the warhead's effects up or down to deal with different targets and environments, he suggests. Other projects in the MCM-ITP are developing lethality models for different types of targets, including aircraft, ships and structures. Replacing metal parts in warheads with reactive materials could result in more efficient and increased lethality, and if combined with additive manufacturing techniques warhead costs could also be reduced, say engineers. Additive manufacturing processes could lead to new designs for penetrator warheads in particular. Engineers from MBDA and SMEs Impetus Afea and Fluid Gravity Engineering have developed a 3D penetrator warhead case with a smaller mass than the thick casings usually produced through casting. Using the 3D-printed case means less energy is lost during warhead detonation than with the older cast penetrator. Testing has proved the 3D-printed casing can match the survivability of the thicker casing, and reduced collateral effects can also be achieved, MBDA says. The company is now looking to evolve the MCM-ITP to deal with new technologies that may cut across the eight domains of research, with the addition of a new ninth, open-challenge domain that will be more flexible for future program needs. A name change is also in the offing, with MCM-ITP being renamed the Complex Weapons Innovation and Technology Partnership (CW-ITP) from early next year. https://aviationweek.com/defense/european-missile-research-paves-way-collaborative-weaponry
