Power Armor For the Elderly

aicrules writes "The question of how to care for the growing number of people in the upper age bracket has a new answer - assistive power armor for the elderly." From the article: "The sleek, high-tech get-up looks like a white suit of armor. It straps onto a person's arms, legs and back and is equipped with a computer, motors and sensors that detect electric nerve signals transmitted from the brain when a person tries to move his limbs. When the sensors detect the nerve signals, the computer starts up the relevant motors to assist the person's motions. Sankai says the suit, dubbed 'Hybrid Assistive Limb (HAL) 5,' can let a person who can barely do an 176-pound leg press handle 397 pounds."

      i've always wondered, if you lifted imaginary weights, but you put a lot of energy into trying to lift it, meaning you can actually see my arm shaking trying to lift this imaginary weight, how much exercise am i doing? is it really the same as lifting 0lbs? i mean, you can be sweating lifting imaginary weights. i know that the resistance isn't there, but much works is my body doing when imagining resistance and my body against it?

      There was a study done a while back where some people lifted little finger weights, some did nothing, and some imagined lifting finger weights. The people actually doing the weights increased strength by 30% or so (IIRC), and the people imagining it increased by 20%, with no effect for the controls. Apparently it stengthens the nerve pathways that control the muscle, thereby allowing stronger signals to get through. So, there ya go, imagination can make you stronger! :D

      If you use your own muscles' tension to create resistance to a given motion, as in say a military press, you can build strength in the same muscle groups as with the traditional, weighted equivalent, but in my experience it's wasted effort compared to just lifting heavy weights with low repetitions, or the more difficult bodyweight exercises like one-armed pushups and one-legged squats.

      These latter two types of strength exercises are more efficient strength builders than pure tension exercises like the one you describe because they are less apt to "burn out" the muscles when done properly. Believe me, I used to do kung-fu type tension exercises as a kid and I can say they accomplished very little for the amount of effort I put into them. They're more of a supplement to real training.

      Get Pavel Tsatsouine's book, The Naked Warrior, and start practicing the bodyweight exercises if you don't want to use weights--you'll be a believer in no time.

    Can anyone see anything other than cost per suit preventing this being used as an aid for modern soldiers

    No, which is exactly why and what for: to enable soldiers to carry more armour and dish out more firepower.

    Don't think for a moment that military applications of super-strength will mean Superman-style punching villains in the face. It won't. Ever.

    However a major topic throughough the last century has been the weight of ammo and equipment a soldier has to carry. It's a real issue. That's one of the reasons (among other factors) why we've moved to smaller calibres.

    Put some powered armour on those soldiers and suddenly they can carry a lot more heavy weaponry and ammo.

    Individual armour has also been discarded precisely because of weight considerations: you _could_ make a breastplate that could stop a rifle round, but it was impractically heavy.

    Now think the other way around: if you have an armoured exo-skeleton, you can carry enough armour at least over the vital organs to stop even a 7.62mm round or shrapnel from hand grenades and pipe bombs. _And_ this time it's without a mobility penalty.

    You've just made life harder for the enemy soldiers, because now they need to lug around bigger weaponry to take you out, which limits _their_ mobility.

    But perhaps more importantly, and this is really what makes it a wet dream for the military is: enabling soldiers to carry more electronics and a sattellite connection. Giving at least one soldier per squad enough electronics to know exactly where the enemy is, what's happening, where is the squad needed, what should they avoid, etc, is something that can give a _huge_ advantage.

    Nations have been defeated before because basically their chain of command didn't react fast enough. E.g., that's why large armies like those of France or Poland crumbled in the face of Blitzkrieg in WW2. They just weren't prepared to react at that speed.

    Or the USSR in WW2 was massively handicapped by their lack of radios on their tanks.

    Now picture giving each squad a direct link to their officers _all_ the time. Bidirectional. You can know _exactly_ what's happening at each point, in real time, and the soldiers can know exactly what's expected of them. You can instantly see when your troops are being pinned and flanked, and how, and you can tell them exactly how to counter it. Better yet they too can see a bigger picture and react in a more intelligent manner - By copying and pasting from old slashdot stories.

    It's something that can really make or break a battle.

  5. This may seem funny to us... by not-enough-info · · Score: 4, Interesting
    You have to realize though that the Japanese are desperate. While we have plenty of able bodied people to care for elderly, they aren't so lucky. In a matter of decades their work force is going to implode under the strain of an older population.

    I can see this as fallout (no pun intended) from WWII really. The US had a baby boom; Japan had to cope with assimilating, through occupation, a new culture. A culture that was somewhat incompatible with their social norms. Now birth rates are falling because what is left of their old culture in their personalities and sensibilities is grinding against their new culture's pace and density. Raising a family is "lame", so nobody is doing it. All this, of course, is gross over-generalization; take it with a giant grain of salt.

    If you ask my opinion though, now is the perfect time to start your own Japanese empire.
    1. Move to Japan

      The problem is LI #1 - Move to Japan. The main reason we in the US won't have as much of a problem with aging boomers as Japan (who also had a post-WWII boom) is because we're more than happy to allow imigration (legal or otherwise) to bolster the ranks of the working. Japan is still a very closed society. If a country wants to maintain racial purity they have to have lots of children. Japan failed to do that, and is unwilling to increase the number of imagrants into the country. Now they are beginning to embrace women in the workplace (no pun intended) because they have no choice. Unfortuantly this will make things worse, due to women not having to rely on a man for food and shelter (and not getting married), and the tradition of long hours at work and scheduling conflicts. There was a NOVA about this subject a few months ago. They profiled a rural school with 1 student. When he graduates, the school will close down because there is no one after him. The elderly farmers in the area have no one to help take care of them as they age. I guess there's always harri-karri...

    I don't trust old people with driving none-the-less built in computer suit.

    I think there other issues such as what happens if they have a medical condition (or otherwise) that could lead them to strike out at others? Arm then you give them a warrant to do anything -- provided you don't stop them as soon as they start doing things they shouldn't.

    Obviously this could happen regardless of age but can be more common as our bodies break down (i.e. where being elderly comes in). The theory seems sound until you realize the implications of putting such a system in place in practice.

    Now that I think about it, the "armor" could also be controlled by someone else should certain unfavourable conditions be met. This could actually be a very good idea, just don't let control get into the wrong hands.

    maybe athletes can finally cut back on the steriods. i can see these kinda things becoming mainstream, at least in certain jobs. ups could raise the max weight on packages. moving to a new house would become much easier, you could just rent a few of these for you and u'r friends (no drunken battlebots plz). of course the military industry will be all over this. if enough ppl had it, other products would prolly change too. portable computers wouldn't need to be as lite. the human scale that you design around would change. you wouldn't be limited to things that can only be done under normal human strength. of course the scary part is, where to draw the line. each generation of these will be faster and quicker. evolution at a breakneck speed. and the disparity between rich and poor would be even greater. rich and powerful will have a whole new meaning. and as soon as these get wired to the brain for better reaction times and possible brain enhancements, we've become the borg. maybe i'm just overthinking this and should go back to sleep, but the ramifications r interesting. i can't wait to get mine and OC it!
