  This Army unit will be first to test an exoskeleton that lightens combat load

  By: Todd South Soldiers with the 10th Mountain Division will be the first to test the long-awaited exoskeleton that developers say can reduce injuries, carrying loads and help troops move around the battlefield with ease. The U.S. Army Natick Soldier Research, Development and Engineering Center partnered with the division in February to identify, evaluate and transition exoskeleton technology to the Army. NSRDEC has led exoskeleton efforts for the Army for a number of years. One of the more advanced products that will soon hit the division is made by Lockheed Martin. Army Times spoke recently with company officials about the ONYX device, which will go through phases of testing, beginning as early as this fall. The first phase will include a six-month “development effort” in which researchers work on “quality of life” portions of making the knee- and hip-focused device fit comfortably and correctly to the soldier's body, said Keith Maxwell, senior program engineer for the company's exoskeleton technologies. That will be done with 10th Mountain soldiers later this year. And that's not the only high-tech gear that 10th Mountain soldiers will be testing. They're one of two units, along with the 101st Airborne Division, that will take robotic vehicles to act as gear mules into the formations later this year. That's part of the Squad Multipurpose Equipment Transport program. The program has four vehicles being evaluated by those Army units and a yet-to-be identified Marine Corps unit at Camp Lejeune, North Carolina. For the ONYX, 10th Mountain soldiers will evaluate the changes as they develop an exoskeleton “concept of operations.” A second phase will include a cycle that starts in early 2019 to add in faster, quieter actuators to the device; those will also be tested by 10th Mountain soldiers. Then a third round will test for ruggedized operation before the Army decides if or when the tech will be fielded. Officials estimate the device could be ready for fielding as early as 2021. The most challenging movements of climbing, especially with a load, up stairs or mountain faces, present strain on the endurance and strength of a soldier but also put them in a position for significant injury to their back, hips or knees. The exoskeleton allows a soldier to transfer the weight of the load from his or her frame to the device. Much of the work began years before with the Human Universal Load Carrier, or HULC. But that system was too bulky and required more power, which meant more batteries. More batteries meant more weight, which could cancel out the benefits of transferring load bearing, Maxwell said. So, with the ONYX, developers incorporated changes made in systems that came after HULC – removing added power requirements and adding technology that had been used in the medical field by B-Temia for people with extremity injuries. Last year, a University of Michigan study by their Human Neuromechanics Laboratory showed reduced fatigue using the knee-stress relief device that is part of the ONYX exoskeleton called the FORTIS. The university had four participants carry a 40-pound backpack at different speeds on a treadmill at a 15-degree incline. All showed reduced exertion when using the exoskeleton, according to the study. While the ONYX device has shown considerable promise in clean environments, the big step will be ruggedizing it for fieldwork, Maxwell said. “That's the hardest part of all, ruggedization,” Maxwell said. And that's a matter of time and investment. “None of the stuff we're facing is insurmountable,” Maxwell said. Waterproofing the device is paramount, he said. The standard is for it to be submersible to three feet of water for 15 minutes. While the current device focuses on the lower body, which carries most of the load and presents most soldier injury problems, there are technologies that are coming from this research that could eventually work their way into upper body support and possibly the TALOS suit that is being developed by Special Operations Command. https://www.armytimes.com/news/your-army/2018/06/05/this-army-unit-will-be-first-to-test-an-exoskeleton-that-lightens-combat-load/

  New head of Strategic Capabilities Office wants to focus on AI

  By: Aaron Mehta WASHINGTON — The Strategic Capabilities Office is under new management, and its new director intends to doubledown on the agency's emphasis on artificial intelligence. In his first interview since taking over the office, Chris Shank, the new SCO director, made it clear he sees artificial intelligence as a sweet spot for his office. Roughly one third of SCO projects deal with autonomous systems, machine learning or AI in some way, Shank said, including long-range fires programs, cyber programs and some assorted with special forces. Shank is the the group's second leader, following Will Roper, the office's founder who is now the Air Force's top civilian acquisitions official. But don't expect major changes in how the office works. “My job is to keep momentum going,” Shank explained. “It's a very high ops tempo group that [Roper was] able to recruit and attract into the office, in terms of working synergistic teams around that. What I am trying to do is take it from a startup organization to a long-term sustainable one.” Although they share some DNA, the SCO's mission is different from that of the Pentagon's technology office, the Defense Advanced Research Projects Agency. Where the latter is focused on finding and prototyping the game-changing technologies for future battles, the SCO is trying to understand existing needs and address them in new ways. Getting those projects from tests to prototype to a tool used by the services remains a central challenge, Shank acknowledged, but he said that is one of the office's core function. “Where SCO lives is the valley of death,” Shank said, referencing a term for when technologies infamously tend to fail. The SCO had been reporting directly to the Secretary of Defense, but under the Pentagon's recent reorganization, it now reports to Undersecretary of Defense for Research and Engineering Mike Griffin. Shank acknowledged the importance of coordination within that office, particularly with AI, which now has a number of different centers of gravity within the Pentagon – a $2 billion push by DARPA, an AI center under Chief Technical Officer Dana Deasy, a directorate under the R&E enterprise, as well as various service-level initiatives. The R&E enterprise has weekly meetings to deconflict investments in AI, Shank said, emphasizing the different business models and goals between the groups. Shank described two programs — each named after pieces of the Iron Man movie mythos — as examples of how SCO can use AI to assist the services in the near-term. Paladium is a broader Navy logistics effort, which involves “smart sustainment” in support of fourth-generation fighter aircraft. A sub project for that is JARVIS, which involves putting a robotics suite out into the field with maintainers that can scan existing parts and quickly re-manufacture them. Shank said the office identified two parts that would require around 2,000 man hours to build out; JARVIS should be able to quickly recreate those, saving both time and the potential errors that come from human-machined pieces. Perhaps those projects aren't as shiny as some of SCO's other programs, such as the Perdix drone-swam, but finding areas where AI can be injected onto existing system and where “the human brain doesn't have to work” as hard will have benefits across the Pentagon, Shank said. The office is primarily focused on the Indo-PACOM and European Command theaters, Shank said. However, he expects to soon provide an update on the Sea Mob/Ghost Fleet initiative, which involves converting existing naval vessels into unmanned systems. He also indicated that there would be unmanned projects in air and land that are unveiled in 2019. One looming cloud for the office: an attempt earlier this year by members of the House Armed Services Committee to kill the SCO by 2020. However, when asked if he was concerned about that proposal, Shank flatly said “no.” He traveled to the Hill shortly after taking office to address that specific issue. In describing the conversation with lawmakers, Shank said, “'I know this wasn't your intent, but this impacted both morale and my ability to recruit talent into the organization,'” he said, “and they [said] ‘that wasn't our intent.'” The SCO is working on a report for Congress on the future of the organization. https://www.defensenews.com/pentagon/2018/09/21/new-head-of-strategic-capabilities-office-wants-to-focus-on-ai
