  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/

  The chief of naval research on AI: ‘If we don’t all dogpile on this thing, were going to find ourselves behind’

  By: Jill Aitoro Most of us are comfortable with Suri, or Alexa, or “Hey, Google.” But many will tell you artificial intelligence and autonomy in the context of military operations is a whole a different animal. That said, if you ask Rear Admiral David Hahn, one factor remains the same: the need for trust. Understand the algorithm and the consequences, he argues, but then relinquish (some) control. He shared his vision of AI in the military in an interview following the Defense News Conference in September. Much of the discussion around artificial intelligence and autonomy involves the proper role of machine versus human. Where do you stand? We're at an inflection point for what technology will allow us to do. For artificial intelligence that could be brought to bear in the military context, there has been anexpectation that the human is always going to be in control. But as the sophistication of these algorithms and the sophistication of the application of the tools now out there mature, and are brought into the operational space, we need to get at a place of trust. [We need trust] between the algorithm, what's behind that curtain, and our ability as the humans to agree that the decision or the space that it's going to operate in – the context in which its making that decision – is understood by us. And that more and more is going to have to happen at machine speed, because when machines are interacting with machines, we're going to have to comfortably move from a human in the loop to a human on the loop. That doesn't mean it's an unsupervised act; it means we understand it well enough to trust it. So, there is relinquishing of control? There is, but there are clearly pieces of our system today where we do that. That happens when you let your car park itself – you relinquish that control and trust that the machine is not going to run into the grocery cart behind you or the car next to you. That's already part of the conversation. And as we get more used to machines performing, and performing accurately over and over and over, our ability to trust these machines [increases], if we understand the algorithm and the consequence. It's not ‘I just ran into a shopping cart' if the consequence we're talking about is the release of weapons, or something along those lines; but we've gotten to the point where we're comfortable [because of our understanding of the technology]. We had similar conversations in recent years on cybersecurity, in terms of confidence in the technology, whether we could be sure networks are properly protected, and accepting a degree of risk. Has progress there helped with progress in AI? I think it's helping and it will continue to drive us toward this human-machine teaming environment that we all see coming. There are clearly pieces of our system that make us uncomfortable. But we see more and more, that if we don't take the action to allow it to occur, we might as well have not even created the tool. It's a shift in culture, beyond policy. Is that happening yet? Or is it too soon to expect that? I don't think we're too early, and I think it's happening. And it's going to be one of those things where we didn't know it was happening, then we find ourselves there. Ten years ago, the App Store opened. Can you imagine a world without the App Store and what that's enabled you to do in your daily life with your smartphone? The young people today are almost at a point where there was never a world without a smartphone, there was never a world without an App Store. If you start at that point, this is not a big leap. It's happening around us, and we just need to find a way to keep up. Looking ahead, 5 or 10 years, how do you see AI being used in an operational capacity? The limiting factor is not going to be the tools. To borrow a phrase, the ‘democratization' of the tools that are associated with developing AI capabilities will allow anybody to work on the data. Our challenge will be whether we have harnessed our own data and done it in a way where we can make the connections between relevant data sets to optimize the mission effect we could get by applying those tools available to everybody. That's our challenge. And it's a challenge we'll need to figure out within each service, amongst the services in the joint environment, from that joint environment into the same space with partners and allies, from the DoD or military into the industrial base, all while moving seamlessly across academia, and [keeping in mind how] the commercial industry plays. If we don't all dogpile on this thing, were going to find ourselves behind in this great power competition in a very important space. So, establish a playbook so to speak? And recognize that as soon as we've established that playbook, it will change. https://www.c4isrnet.com/it-networks/2018/11/06/the-chief-of-naval-research-on-ai-if-we-dont-all-dogpile-on-this-thing-were-going-to-find-ourselves-behind
