DARPA Funds Harvard's Soft Exoskeletal Suit

An anonymous reader writes: The military and private contractors have been toying with exoskeletal combat suits for a while, but Harvard's Wyss Institute has a new take on the concept. Rather than using a hard metal frame and the massively overpowered mechanical servos necessary to move it, the Soft Exosuit is a lightweight mesh of webbing combined with a series of strain sensors and basic microprocessors. "The suit mimics the action of leg muscles and tendons when a person walks, and provides small but carefully timed assistance at the leg joints without restricting the wearer's movement." The suit continually monitors its wearer's body position, movement, and muscular strain, providing small amounts of targeted support. The team has now received $2.9 million in funding from DARPA to refine the suit's design. They say they'll be working on medical applications for the suit as well as military ones.

      If you improve the endurance of a soldier you *have* improved their weight carrying capacity. But I get what you're saying. They won't be able to lift 300lbs instead of 100lbs and put it on a shelf. However, they might be able to realistically haul say 80lbs of gear 15 miles instead of 50 lbs of gear. Of course that might be how much the batteries weigh to keep the thing running for a day. :)

      We want HALO-like suits that will let us jump 50 feet high, jump out of an airplane and land safely with no parachute, and lift 500 lbs with one hand while accurately shooting at something a mile away with a fully automatic weapon in the other.

    I think that if they can get muscle wires working well enough, this suit has plenty of potential in either hard or soft form. For soldiers, it could automate the manual marching process and do much for endurance, but has limitations in combat situations if it's called on to do things the human body couldn't do well. It still would need some sort of power generation while in use to keep that system running as long as the human does.

      You want the body armour for combat use, so you want an iron man suit. Having powered legs to increase your capacity is useful too, though not as intimidating. As for the batteries- you can run a fuel cell off of diesel using a reformer, and that's easy to get on a battlefield.

  8. First? by Dereck1701 · · Score: 1

    They may be the first to actually begin development of such a exosuit but this kind of application has been imagined in multiple fictional accounts(Spriggan movie & Crisis game series off the top of my head). It'll be interesting to see a full fledged pro-type (most of the stuff in the videos looked like non functional demo gear) but last I heard our artificial muscle tech was pretty pitiful. There was a big claim a while back that a breakthrough had been made using modified sewing thread and fishing line that was actually more efficient/powerful than natural muscle but I don't know if anything came of it. Also their designs seem to put the full brunt of the load on a persons own skeletal/joint system, possibly resulting in injury. While I am sure there is a way to add in some kind of exterior joints/"bones" to take some of the load off the wearer that technology and the muscle technology will take a LOT of advanced research to make a reality.

    But nature always finds a way. Teeth become stronger and sharper to pierce the hide directly, armored gullets and crops evolve to subject swallowed prey to slow grinding until the hide is pierced and the juices leak out. Suction arms pin the prey to rock as a horny beak drills through the exoskeleton. Birds lift the prey into the sky and let gravity do the hard work, gathering the yummy bits from the wreckage.

    The military should be focusing its research on making soldiers better at hiding, smelling and tasting really bad.
