unmanned systems

Researchers have taken a new approach to developing robots—using smaller robots known as “smarticles” to unlock the principles of a potentially new locomotion technique. The 3D-printed smarticles—short for smart active particles—can only do one thing: flap their two arms. But when five of these smarticles are narrowed in a circle, they begin to push one another, forming a robophysical system known as a “supersmarticle” that can move by itself. Adding a light or sound sensor allows the supersmarticle to move in response to the stimulus.

The U.S. Marine Corps is exploring the use of a family of unmanned aerial vehicles to deliver vital supplies to Marines in combat. Drones would remove humans from the dangerous role of forwarding essential logistics to warfighters while allowing greater flexibility of delivery.

Once developed, these drones also could have civilian emergency response applications. Instead of speeding ammunition to Marines on the front lines, the vehicles would be used to provide emergency supplies to civilians left without power, food or clean water following a natural disaster. Either mission would have the same sense of urgency; only the cargo would be different.

The already-complex Marine Corps mission is about to become more intricate as the Corps strives to incorporate new methods of warfighting and countering enemy capabilities. Viewing adversaries has given the Corps a glimpse of the future, and major changes lie over the horizon.

These points were hammered home by Lt. Gen. Robert S. Walsh, USMC, commanding general, Marine Corps Combat Development Command, speaking at the day two morning keynote address at West 2018 in San Diego. From amphibious assaults to information warfare, the Marines are incorporating new capabilities that will lead to an entirely new way of waging combat, the general allowed.

Robots, drones, automated devices—they are but a few of the names given to unmanned systems proliferating across the military and the commercial sector. The sky’s the limit for unmanned aerial vehicles, and no ocean is too deep for their underwater counterparts. Yet the potential for these devices, which seems unlimited, is being hindered by the human element they support. Planners must abandon convention and explore disruptive approaches that will allow unmanned systems to reach their full promise.

The Defense Department's futuristic research agency reached a huge milestone in its robot sea vessel program Thursday, christening the unmanned prototype "Sea Hunter" and entering a two-year extended test phase.

Early this year, violent floods brought immense destruction to communities in the Zambezia province of central Mozambique, Africa, endangering thousands of children and adults. Floods ravaged the region, decimating roads and bridges; 70 percent were unusable for ground vehicles, and some were unmanageable even by foot. In the absence of electrical power and a way to resupply gasoline for generators, refrigerated vaccines became unusable. Furthermore, damaged roadways meant that much-needed supplies never arrived.

U.S. Army officials envision a future in which robots are integral members of the team performing a range of missions, whether hunting for roadside bombs, searching for threats inside buildings, lugging heavy equipment or packing heat in the form of a light machine gun or missile launcher for troop protection. The Army’s existing robotics road map is updated routinely, but now officials are looking for ways to realize their vision sooner than planned.

A developmental U.S. Navy project aims to provide a creative solution to the challenge of how to move unmanned underwater vehicles to their proper point for submersion. The project is creating a bio-inspired seacraft that will use flight to reach its destinations.

The inertial navigation system (INS) market size is estimated to be $2.75 billion in 2014 and is projected to grow at a compound annual growth rate of 10.98 percent to reach $4.63 billion by 2019, according to Research and Markets, a Dublin-based market analysis firm. Though North America and Europe have the largest market for INS in terms of commercial and defense aviation, military and naval applications, a lot of INS development programs have been launched in Asia-Pacific and the Middle East.

Northrop Grumman Systems Corp., Integrated Systems Sector, San Diego, California, is being awarded an $8,465,734 modification to a previously awarded cost-plus-fixed-fee contract (N00019-12-C-0126) for the extension of engineering and software sustainment services in support of the Vertical Take-off and Landing Tactical Unmanned Aerial Vehicle Fire Scout MQ-8B. The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity.

Longbow LLC, Orlando, Florida, was awarded a $25,197,219 modification (P00006) to contract W58RGZ-12-C-0049 for the production of 17 radar electronics units and unmanned aerial system tactical common data link assemblies, a P4.00 software upgrade, and associated gold standard hardware for production testing. Army Contracting Command, Redstone, Alabama, is the contracting activity.

The U.S. Navy has successfully demonstrated the Autonomous Aerial Cargo and Utility System (AACUS), which allows current, full-size helicopters to be remotely controlled by a tablet device. Rear Adm. Matthew Klunder, USN, chief of naval research, recently revealed that two young Marines at Quantico, Virginia, were able to land a full-size helicopter autonomously on an unprepared landing site with just one touch on a mini-tablet.

Thales recently announced the company has signed a memorandum of understanding with the Qatar Armed Forces to assist in the development of an Optionally Piloted Vehicle-Aircraft (OPV-A), a high-performance intelligence, surveillance, target acquisition and reconnaissance system. The OPV-A will be a hybrid between a conventional and unmanned aircraft capable of flying with or without a pilot on board. Unimpeded by a human’s physiological limitations, an OPV-A is able to operate under more adverse conditions and/or for greater endurance times. The airframe, to be selected by the Qatar Armed Forces, will be integrated with a mission systems capability to enable the optionally piloted capability.

Unmanned systems for reconnaissance, surveillance and warfighting have grown so quickly in popularity that they are spawning a familiar list of challenges that must be met sooner rather than later. Many of these issues have arisen with other military technologies that became popular quickly, and planners found that fixing these problems was significantly more difficult the deeper the technologies were embedded in everyday military operations.

The U.S. Naval Research Laboratory (NRL) demonstrated the launch of an all-electric, fuel cell-powered unmanned aerial system (UAS) from a submerged submarine. Operating under support of the USS Providence and the Naval Undersea Warfare Center-Newport Division, the NRL developed the eXperimental Fuel Cell (XFC) UAS, which was fired from the submarine’s torpedo tube using a Sea Robin launch vehicle system. The Sea Robin launch system was designed to fit within an empty Tomahawk launch canister (TLC). Once deployed from the TLC, the Sea Robin launch vehicle with an integrated XFC rose to the ocean surface.

A vision-driven robotic arm will enable the precise long-range delivery of a payload weighing up to one pound into difficult-to-reach environments. The capability is being made possible through a Defense Advanced Research Projects Agency (DARPA) project that adds depth perception to the range of unmanned aerial hover vehicles’ features. Using stereo vision, the unmanned aerial vehicle can estimate a target’s position relative to the hovering aircraft in real time, and then the system tracks where the payload must be placed and the motion of a robotic arm. Control logic maneuvers the vehicle and directs the robotic arm to engage a designated target and to place the payload.

The Pennsylvania State University, University Park, Pennsylvania, was awarded a $34,077,057 cost-plus-fixed-fee contract for the research and development services in support of electro-optical and infrared technologies; night vision technology; and laser technologies and payloads for unmanned platforms. The U.S. Army Contracting Command, Research Triangle Park, North Carolina, is the contracting activity.

How do you stop a rifle round shot at a soldier’s head? Researchers from the U.S. Army and the Massachusetts Institute of Technology are in the nascent stages of developing technologies to field unmanned assets that might do just that.

The U.S. military for decades has employed unmanned systems—from dropping bombs miles above the Earth’s surface to detecting underwater mines from miles below. Now, researchers and scientists are on the threshold of tweaking the technology as part of a new concept for the use of unmanned assets, which could bring an army of autonomous protective robots to the battlefield.

As the U.S. Navy modernizes information systems across the fleet, one organization is responsible for researching, developing and fielding the full range of technologies in the Asia-Pacific region, providing complete life cycle development and support for systems, from concept to fielded capability.

Systems entered in the U.S. Navy’s 17th annual RoboSub competition, held July 28-Aug. 3, are far more sophisticated than the toys that competed in the first competition, which was launched in the wake of the Sept. 11 terrorist attacks.

“In the earlier days when we first did this, the systems were considered to be some kind of toys,” says Steve Koepenick, an autonomous systems expert with the Navy’s Space and Naval Warfare Systems Center, which hosts the competition. “They are now tools. They’re part of the kit that our sailors and Marines take into theater with them. That’s reflected in the competition and the things the students are trying to do.”

The U.S. Navy's pet project for a carrier-launched unmanned aerial vehicle came under fire by experts this week, who told a congressional subcommittee that the sea service’s proposal is redundant, already obsolete and will leave naval forces with a vulnerable platform.

The Navy has dedicated years toward the creation of what it calls a "persistent, aircraft carrier-based intelligence, surveillance, reconnaissance, targeting and strike capability to support carrier air wing operations" platform, which has become known as the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) system.

U.S. Army officials envision a future in which ground and air platforms share data and where soldiers at a remote forward-operating base easily can access information from any sensor in the area, including national satellites or reconnaissance aircraft flying overhead. To achieve this big data vision, the service has initiated three pilot projects designed to provide Google-style access in a tactical environment to the lowest echelon without overwhelming soldiers with unnecessary data.

U.S. Defense Department officials intend to complete a departmentwide spectrum strategy road map this month, which will make more frequencies available to warfighters, provide greater flexibility—especially for international operations—and ultimately allow warfighters to conduct their missions more effectively. At the same time, however, some are suggesting a nationwide strategy to allow for more innovative and effective spectrum management and sharing across government and industry.

Representatives from the U.S. Army and Air Force, along with 17 NATO nations and three partner nations, will participate in a joint reconnaissance trial at Orland Air Station in Norway May 19-28 to test and evaluate intelligence, surveillance and reconnaissance (ISR) concepts and technologies. The Unified Vision 2014 (UV14) trial will be NATO’s largest-ever ISR trial and will be used as a major stepping stone to provide NATO warfighters with an enhanced set of ISR capabilities.
