Prototype Exoskeleton Suit Would Improve Soldiers’ Physical, Mental Performance

Earlier this week, we showed you Mawashi's UPRISE Tactical Exoskeleton. This is an Army News story on a DARPA-funded initiative to create a similar, unpowered exoskeleton. Guess which one is more mature, the commercially developed model, or the government funded offering? Considering, Mawashi started earlier on development of the UPRISE, it is available today. Unfortunately, the Army doesn't expect their's to be ready for prime time for a decade. By then, our troops may well face niche competitors on the battlefield, equipped with robotic augmentation systems.

Commercial technology development continues to outpace the US military's ability to interact with industry. All too often, we are witnessing companies who give up on the government and offer their wares to the international market. Much of the problem stems in Congress and the Executive Branch which has failed for almost a decade to adequately and reliably fund defense modernization. Furthermore, not only do our acquisition regulations need overhaul, but those serving in acquisition billets need to have a better understanding of how their actions, or inactions affect the industrial base. The military and their labs cannot go it alone, but they are rapidly painting themselves in a corner as the supply chain fades away. We've got to become smarter and faster at assessing and acquiring technologies for the Warfighter.

ABERDEEN PROVING GROUND, Md. — Thanks to a new "suit" being developed by the DOD-funded Warrior Web program, future Soldiers will be able to march longer, carry heavier gear and improve mental sharpness.

The suit has pulleys and gears designed to prevent and reduce musculoskeletal injuries caused by the dynamic events typically experienced in the Warfighter's environment.

Scientists and engineers from the U.S. Army Research Laboratory have been testing variations of the suit for more than three years at the Soldier Performance and Equipment Advanced Research, or SPEAR, facility at Aberdeen Proving Ground.

"We've been primarily focusing on the physical benefits of these types of suits, but we're also interested in the cognitive benefits," said ARL researcher Dr. Angela Boynton. "We're hoping that by reducing the physical burden, that they also have the ability to put more energy into other types of tasks that involve cognitive or perceptual workload."

The project, funded by the Defense Advanced Research Projects Agency, or DARPA, has many partner organizations across the DOD and academia.

The U.S. Army Natick Soldier Research, Development and Engineering Center, the Maneuver Center of Excellence, the Army Capabilities Integration Center and the Military Operational Medicine Research Program met at ARL's SPEAR in June for a soft "exosuit" demonstration and to discuss the path forward for the Army's Warrior Web Program.

The program, which is funded by DARPA, is coming to an end; however, researchers hope to find future collaborators to expand on the progress gained in the current program iteration.

"In the longer term, the systems have benefits to be integrated into larger Soldier systems and can be integrated with other capabilities to provide a marked advantage for our Soldiers and our warfighters in the future," said Maj. Christopher Orlowski, DARPA's Warrior Web program manager. "I think it will take at least another five to 10 years to be ready for the infantry Soldier."

A team of researchers from Harvard's Wyss Institute in Boston, Massachusetts, led by Dr. Conor Walsh, associate professor of engineering and applied sciences at the Harvard biodesign lab, attended the meeting that was held in conjunction with ongoing testing at ARL. Walsh and his team have been working on and testing their prototypes on Soldiers since 2014.

"The meeting was a good opportunity for our team to summarize the progress we have made as part of the DARPA Warrior Web Program to other Army stakeholders and get their feedback on how they see the technology and what further work remains to continue to optimize it," Walsh said.

Walsh said the latest version of the "exosuit" tested at ARL is the result of his team's system integration efforts over the past year. He said the system is much more user friendly as compared to early prototypes and includes improved functional apparel attachments to the body, control systems that adapt to each individual, and actuation systems that are quiet and compact.

Edwin "Eddie" Davis, director of the Maneuver Battle Lab, Capabilities Development Integration Directorate Maneuver Center of Excellence, said he was impressed by what he observed and that Soldiers should have a say in what kinds of equipment they will use in combat.

"Warrior Web is a perfect example where engineers and Soldiers work together 'early and often' to develop a capability that might be useful for the future," Davis said. "It also helps speed up the technology transition and program acquisition. Soldier feedback will help frame the Warrior Web Program outcomes and future Army investment."

Henry Girolamo, NSRDEC program manager for the Warrior Web project, has been with the project since its inception.

"What we're trying to do here is collaborate, so we can keep it going in a beneficial way for the Army and the services," Girolamo said.

Girolamo noted that the SPEAR facility has been highly beneficial.

"We have an indoor lab capability where we can instrument up the Soldiers and keep them in an environment where you can just get pure data on things like treadmills, motion capture and be able to analyze everything in the lab," he said. "You can take them out on a three-mile course where it's more aligned with the environments in which they would be working. We've got the best of both worlds."

Walsh and his team agree.

"Our team has benefited greatly from working with the ARL team and Soldiers. We get to evaluate the system with potential end users who are walking significant distance on the treadmill and over ground," Walsh said. "The feedback we get also informs our ongoing research and developments as we continue to refine the prototypes. Our team is interested in furthering the scientific understanding of how to best optimize these systems for individuals as well as refining the technology by creating more integrated systems suitable for every day wear."

Researchers tested the same group of Soldiers in April and again in June, both with and without the suit, and gathered massive amounts of data.

"If you reduce the physical burden on somebody, there may be some benefits additionally to the amount of attention they can pay to their situational awareness," Boynton said.

Officials are still discussing the path forward.

"I see it as a solution-focused suite of technologies that support a wide array of Soldier issues that we are having to deal with right now," Girolamo said. "We need to iterate the technology a little bit further along to make sure we can actually do that and I know we can. We just need the funding and time to do that."

    While it is great that the military wants to develop their own solution… but all to often their solution might be a bit to close to what industry has already developed… and has fine tuned for efficient manufacturing… the LABS are great and the people manning them want to do the right thing… but when industry hands you the solution all to often it is dismissed… for one reason or another.

    • Erik says:

      On what industry exoskeletons have you performed studies to support your claim?

      • Joe says:

        Why can’t DARPA buy the commercial product and compare it to their efforts?

        Innovation is great, but reinventing the wheel is redundant.

    • AGL Bob says:

      Yeah, look at the evolution of the Nett Warrior project.

    • james says:

      We have worked with the original SPS LDS ‘spine’ which was developed for the marines as well as several backpack style solutions along with our own design. The SPS has all but dropped their ‘spine ‘ for the time being so we will be looking to work with other national security forces.

  2. James says:

    Really, Really. REALLY thanks for another giant waste of tax payers money. Should be criminal wasting my hard earned money like that

    • PNWTO says:

      Yeah… because revolutionizing infantry warfare is such a waste. I heard the phalanx was cost-effective.

      • Rt says:

        This is the exact opposite of a waste of funds!

        Projects like this actually provide the one tiny glimmer of hope we have for actually reducing the stunningly massive percentage of military budgets that go to caring for the injuries day to day combat arms service all but guarantees you will sustain!

        Also, maybe JUST MAYBE one or two guys every once in awhile will EAS with health good enough that an evaluation of their disability rating would actually come to 0%!

        Imagine that!

        A world where at least some guys might not have to sacrifice range of motion and physical wellbeing for the remainder of their days as a consequence of serving their country.

        I am all for stuff like this 99% because of the potential it has for creating less permanently damaged former soldiers with 1% because of the staggering amounts of cash we can potentially save in the process being a distant second.

        • Rob Collins says:

          The waste is in reinventing the wheel. James in no way implied that this product was a bad idea; he said that it was a waste of taxpayer money to not even look at existing technology used by industry.

          Cutting down on injuries and expanding infantry capabilities is a worthwhile goal. Building on existing tech rather than developing it from the ground up in a vacuum will yield a better solution at a lower cost, which we (as taxpayers) are paying for.

          Read, comprehend, THEN react maybe?

    • Carlos says:

      And exactly how is this a waste of time? Even if this is never issued to the Infantry; it can be issued to those tasked with keeping the trigger-pullers supplied over terrain that does not accommodate wheeled or tracked vehicles.

      • Rob Collins says:

        Read, comprehend, then react.

        Existing industry solutions exist, that should be the starting point. The waste is in developing from scratch. THAT’s how it’s a waste. Reducing injury, increasing capability leads to better success for our troops and ultimately, lower costs. I suspect if I could’ve typed in crayon and single-syllable words, someone still would miss the point….

  3. Paul J says:

    5 to 10 years seems to me to be a really long time to perfect a non powered exoskeleton.
    For exemple, it takes 5 years to design and manufacture a new car from “scratch”.

    • grube says:

      You might have a point…if we happened to be living in a world where many millions of non-powered exoskeletons had been manufactured over the past 100+ years by hundreds of companies. For now, the bioengineering/biotech industry can’t even design, build and hand you a new ass.

    • Rob Collins says:

      The interface is directly with human bodies, and that interface needs to be flexible enough to work with varying physiques, probably, and cars have been done for over 100 years.
