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."

      Maybe the battery can be pulled along behind in a twenty-dollar rolly cart. For that matter, so could the 70-pound backpack in the first place!

      A rich Texan in an airport sees a mad-scientist type puffing along under the weight of two huge and weighty suitcases. "Say, pardner, what time is it?" he asks. The fellow puts down his suitcases and refers to his watch, a humming black conglomeration of dials and lights with a miniature satellite dish spinning on top. "It's 10:28:32 here, precisely, and..." (the inventor's eyes flicker to a set of displays) "your flight is on time, your rental car is waiting in Dallas, and your wife is cooking ribs for dinner tonight!"

      "Holy cow! Sell me that durn thing!" says the Texan, and after some intense negotiations the inventor lets him have it for several million in cash right then and there. The Texan straps the device to his arm and begins to walk away.

      "Hold on!" shouts the inventor, pointing to the two colossal suitcases. "You forgot the batteries!"

    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.

  6. Now that is one sweet video by purduephotog · · Score: 5, Interesting

    Took nearly 2 minutes to download, but watching those short steps around... then finding out that the backpack was loaded with 100lbs.... wow.

    Obviously the future of movement and an important first step, no pun intended.

    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.

    The old quote about the yellow pages- let your fingers do the walking- may soon become far more true than you've realized... especially for those born or brought to wheelchair bound.

  7. Centre of balance by dj245 · · Score: 5, Interesting

    I'd be worried about the centre of gravity on this thing. From the picture, things don't look too good. Sure, the person can carry a huge load. But that load is all on his back, with some of it a foot or more away from his body. If he tips over will the legs be any help getting him upright?

    No, it uses a free piston hydraulic pump that runs off catalyzed hydrogen preoxide. Actually quite small and light for the power it provides.

All the while carrying heavy machine guns and small autoloading cannons that these days require crews to move and operate.

    If you're thinking of the same one I am, they came up with jet-powered shoes, which is a similar yet fundamentally different technology.

    This suit enhances strength and load-bearing capability. The jet-shoes enhanced speed alone. There was no back brace or luggage compartment - just big-ass loud shoes :)

    Then again, there was the spring-loaded running suit those guys made. It retained almost as much energy running as a Kangaroo (one of the most efficient runners on the world). With it, people could run really fast and jump high, all without power. True, it was massive and you'd look a dick wearing it, but technologically fantastic.

    is to get this developed to the point where it could replace a wheelchair. The psychological advantage to a person who'd lost the use of his legs to actually stand up and interact with the world "eye to eye" would have to be powerful. It probably also doesn't hurt to keep the muscles moving and the appropriate neural pathways firing.

    Yea, I know, long way to get there from here, but it's a promising first step. Certainly worth some research dollars in my opinion.

    No, Heinlein did not invent these devices any more than Gibson invented the internet (or Stevenson did VR). Scientists and engineers read these books and say to themselves, "Neeto," and then set about to putting in the long hours and frustration to actually make these ideas happen.

    Mucho deserved props to Heinlein et al., but it's the "nobodies" in academic institutions (PhD's and don't forget those indentured servants, aka grad students) and the tinkerers in garages that really make the world go round. Heinlein gets the fame, but sorry, he shouldn't get the credit.
