Powered Exoskeleton Legs

dyoo78 writes "Berkeley Engineers have come up with an ingenious mechanism that almost mimics, well, Borg technology. Developed by UC Berkeley's Robotics and Human Engineering Laboratory, the Berkeley Lower Extremity Exoskeleton (BLEEX) consists of mechanical metal leg braces that are connected rigidly to the user at the feet, and, in order to prevent abrasion, more compliantly elsewhere. The device includes a power unit and a backpack-like frame used to carry a large load. This development bring to the forefront the ability to not only carry large loads in wartime efforts, but may possibly help people with limited muscle ability to walk optimally."

    This is great -- it senses your motions and accomodates you, helping you along:

    The researchers point out that the human pilot does not need a joystick, button or special keyboard to "drive" the device. Rather, the machine is designed so that the pilot becomes an integral part of the exoskeleton, thus requiring no special training to use it. In the UC Berkeley experiments, the human pilot moved about a room wearing the 100-pound exoskeleton and a 70-pound backpack while feeling as if he were lugging a mere 5 pounds.

    There was a /. article a few months ago about a Japanese team of researchers who were working on the same sort of device (I don't recall the name, but I'm sure the dupe-hounds will point it out). But if I recall correctly, that system required control imput, such as from a joystick-like device. That limits the robusteness and usability pretty severely, IMHO.

    Interestingly, this thing runs on a gas engine (which powers hydraulics for the powered joints and provides electricity for the computer controls), and:

    The current prototype allows a person to travel over flat terrain and slopes, but work on the exoskeleton is ongoing, with the focus turning to miniaturization of its components. The UC Berkeley engineers are also developing a quieter, more powerful engine, and a faster, more intelligent controller, that will enable the exoskeleton to carry loads up to 120 pounds within the next six months. In addition, the researchers are studying what it takes to enable pilots to run and jump with the exoskeleton legs.

    So we've got a unit that can carry up to 120lbs of weight. Figure a few more lbs and it may now be able to 'support' a man whos legs no longer work properly. Although this design is based upon feedback from a proper leg to calculate where it is supposed to move/balance.

    A bug in the software could only cause your legs to break if one of two conditions apply:
    1. You have the leg strength to break your own leg and do so by resisting a machine movement.
    2. The machine is designed so that it can manouver so as to break a leg. The machine should have a physically limited range of motion which does not exceed the wearers!

    "The fundamental technology developed here can also be developed to help people with limited muscle ability to walk optimally"

    Having just broken my ankle recently, I could see how - if priced right - this technology would be great for patients recovering from leg injuries.

    I'm wondering how well it actually supports the legs. Assumedly, one could splint or cast the broken part of the leg/ankle/etc, and allow the mechanics to take weight off the broken areas.

    Even if it weren't useful for an actual break, it would definately be great for the recovery process. I'm getting my cast off tomorrow, but I can see that my muscle atrophied rather quickly. 5 weeks, and my once well-formed muscles are now rather thin (the other leg got a lot stronger though).

    An exoskeleton would assist the weak muscles, while the movement should force movement which would strengthen them over time. I'd go for one if I could get it!
