First Military Exoskeleton Reaches Prototype
JonathanGCohen writes "The U.S. Military has created the first ever prototype for an exoskeleton to be worn by soldiers capable of making its 100 pound weight and a 70 pound supply package feel like five pounds." From the article: "Bleex 1 consists of a pair of hydraulically powered leg braces, more than 40 electronic sensors, a control computer, and an internal-combustion engine providing power from an attached backpack. The plastic and carbon-fiber braces are affixed rigidly to the soldier through a customized pair of standard Army boots, with more compliant and giving connections at the chest and waist. These looser connections prevent blisters and abrasions."
This is not news.
It's been done before, and it's been done better.

Which would you rather do: Carry 70 pounds throughout your journey, or carry 5 pounds for the first 15 minutes and then well over a hundred for the rest?
Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?
the newer version will allow soldiers ... wearing it to move faster than 6 feet per second.
thus actually enabling a real version of "The Wrong Trousers"

Here is Lieutenant Ripley testing the device.
Trolling is a art,
Perhaps this can be adapted to civilian use to enable the traditional "groom carrying the bride over the threshold" maneuver that is becoming increasingly more difficult in the US.
I suspect the biggest obstacle to comfortably using exoskeletons is responsiveness. If you want to move your hand, you just think about it and it takes a few milliseconds to move. With an exoskeleton, you have to hit the sensors (perhaps past their critical point), and the hydraulics/whatever has to kick in and move it. How long does that take?

that's great, but can it find Sarah Connor?

TFA says, and I quote "Carrying a quart of military standard JP-4 gas". Now as a member of the US military, I will not wear this. JP-4 has a very low flash point and is very unstable, not to mention it is a JET FUEL, one spark and you would be toasted. A better alternative would be JP-8, which while still jet fuel, you can throw a match into and nothing will happen since it's flash point is extremely high. Either way I personally don't want to have a quart of jet fuel on me the next time I go to the desert...just sounds like bad news to me.

If the wearer/opeartor falls down, can they stand up again unassisted?
I get a picture of beached whales or insects on their backs.
Not trolling, I really want to know!

It would really suck to be wearing one of these things when an EMP bomb goes off over the battlefield. I'm sure 170 pounds is not going to feel like 5 pounds after the electronics shuts down.

This is far cry from something useful. Soldiers do a lot more than walking. What about running, diving, low crawling to some cover, then firing from a crouched postion?
Imagine the chicks you could pick up wearing one of these babies :-)
Yeah, but then you have to deal with them yelling "Put me down, put me down!"
I really recommend reading Forever Peace by Joe Haldeman. It explores some of the issues (many of them moral) that come about when one nation can make war on another nation with no risk to its own men (through the use of robotic suits that have eventually had the humans taken all the way out). We're definitely headed that way...
It's a fabulous book - from the same guy who wrote Forever War, but it's not a series or anything.
Anyway, here's a question to toss out:
If one man can cause pain to another man with no risk to himself, then it's basically torture.
If a group of men can do it to a different group of men, what is it?

During development, an operator donned Bleex 1, which weighed about 100 lb, along with a backpack carrying a 70-lb load. He could walk at about two steps per second (or 6 fps) and it felt like he was only lugging a 5-lb load. The first prototype was restricted to walking on flat terrain and not-too-steep hills, but the wearer could also squat, bend, and swing from side to side, as well as step over obstacles. The suit is water resistant and will float, according to its inventors.
Now at last I realize why I have been playing so many futuristic soldiers in games that can carry sixteens different heavy weapons weighing hundreds of pounds, but cannot jump over a three-foot tall wall. They all had the Bleex.

You're kidding, right?
The only force coming out of the springs would be the force you used to compress them. So instead of using that force to just carry the damn load directly, you're using that force to compress the springs to carry the load. Add to that the force needed to carry the springs themselves, and the force lost through entropy, and you've got the stupidest powered exoskeleton idea I've heard all day.

"Help. I've fallen and I can't get up!"
This exoskeleton sucks for defending and going after people in cities, close alleys.
It would be good if they figured out how to enclose a soldier in plated armor strong enough to withstand a IED (although that maight be a lot of armor).
The main benefits of that would be that even though you are slow you can take a punishment and still be able to get into alleys, buildings, and other places a M1Abrahms can't get into.
Then again... It would be more logical to send in a remote controlled robot with a machine gun on it.

A term has already been coined for this kind of armored exoskeleton system:
MechWarrior.
I saw this and being in the military, I had some questions. First about the article:
philoneist is very sketchy about this article and points to machinedesign and DARPA. I goto machine design and the entire article is undated giving no clue as to how old this thing may actually be. Now I start digging, most articles outside of the ones that are referenced in /. are in the 2003-2004 timeframe. I had to really dig to find ANYTHING about bleex in DARPA. This does not seem to be breaking news based on what I was actually able to find.
Now some valid points about this program were raised. My big question is what happens if said soldier/sailor/airman/marine etc is carring near max load and this thing suffers a catastrophic failure... Some special forces can handle 100 pounds of gear, but 200 pounds, catastrophic failure... In a word, Yikes!
I think DARPA will be better off looking into the cooling systems and making things smaller rather than helping us carry bigger and more...
Of course, thats just my opinion, I could be wrong...

Many of you are asking questions of "how will it perform in combat, can operators crouch/dive/roll/prepare a five course dinner/shoot/etc, and what happens when it runs out of gas?"
This is why we have the prototype stage when we build something.
When Goddard launched his first rockets, people didn't say "Yeah, but how're you going to get to the moon on that?"
You build, find the shortcomings of your design, improve, and test again.
The suit probably doesn't have any practical application now, but future versions in five - ten years might allow military mechanics to fix heavy vehicles quickly, and in 20 - 50 years, our soldiers might be able to carry better body armor into combat with less restrictions than the current body armor (which is heavy in its own right).
I like the idea that our soldiers who are being shot at will eventually be able to move faster, shoot more effectively, wear more protection, and be better equiped than their enemies.
Got to love how any military product has to have a PR photo ready first, results later. Research in any other field doesn't need consumer-electronics-level designers quite so early in the project. Something about that gives me the willies.
I was watching a documentary on the race to build the next generation fighter jet, and time and time again, the main argument in favor of the X22 was that the other design looked weird.
Yeah, plan your multi-billion dollar expenses on the sexiness of the machine boys, not on the functionality. I too get "the willies" thinking that people this infantile are sitting with their finger on the metaphorical nuclear button.
You can't take the sky from me...
The only problem "the nature" has solved has been the problem of how to reverse a motion produced by one muscle. The solution is to pair a second muscle with the first, so that any muscular force exerted to close a joint can be reversed by a muscular force to open the joint, and vice versa.
Nature, having a much firmer grasp of thermodynamics than you do, has not bothered trying to solve the problem of a magical system that produces a power output greater than its power input.

My question is why this exoskeleton? Why not some vehicle that can resist a blast from a roadside bomb?
If the military's research into new technologies for various applications had to stop because something else was also (or more) pressing, nothing would ever get done. Things like the internet we're using right now, GPS, and countless other defense initiatives overlapped in R&D and always will. Personally, I think exo-skeletons like this are most likely to be used, along with more armor, when a medic or other rescue guy needs to hop out of an armored vehicle and assist in moving a wounded 250-pound Marine into the shelter of the vehicle. Tasks like that are exactly hand-in-hand with other work done on bomb/mine-resistent personnel carriers and transport vehicles. A rescue squad is going to be a lot more likely to step out into sniper fire if they can handle their own substantial armor and carry a large, gear-laden soldier 50 yards into the clear. Also, this is how you get geeks to enlist.
Don't disappoint your bird dog. Go to the range.
An internal combustion engine? One thousand PSI of hot hydraulic fluid coursing through steel veins running throughout my lower torso and legs? And gasoline? On my back? While I'm being shot at? I'm game!
1)6 feet/sec is only about 4 mph. Not too fast.
I am all for the advancement of technology to aid our military. DARPA has a lot of goodies on their shelf that many of us would like to be completed.2)I can ruck with over 100 lbs on my back for a few hours. Days without even lugging JP-4 around.
3)Do I need to carry 200lbs and sound like a chainsaw? This just makes me more of a target.
4)The user can duck and squat, but if under enemy fire could he engage and overtake? Or fall prone, return fire, and *get back up*?
Years from now Bleex will be looked at as the grandfather of the giant robot mecha tanks we send our soldier to war. Full Metal Panic anyone?
Regular underwear, long underwear, insulated shirt/pants, maybe another layer on top of that, overwhites, Bunny Boots, glove liners, Arctic Mittens, balaclava, goggles, etc. etc. Then there is skis/snowshoes/poles, Arctic canteens, and lots of gear. Then add to that a main and reserve chute if you're Airborne (like me), knife, weapons, ammo, cleaning kit, protective mask, maybe a radio and batteries, binos, rope, crampons, etc. etc.
I remember an old poster at one army post that had a pic of a guy carrying a fridge on his back, with the caption "Don't be an ass, leave it behind." I wish.
I'd like to see how this performs while climbing uphill over deadfalls in deep snow at -40 below zero.

I'm not convinced that an exoskeleton will enable a footsoldier to take on a tank of the same tech level.
A foot soldier can already take on a tank. http://www.defense-update.com/products/r/rpg.htm
Imagine a soldier carrying a ton of armour, yet able to move almost as quickly as a man, yet impervious to most weapons...
Well, based on other posts, it looks like armor ain't what it used to be. But imagine a soldier carrying a hornet's nest of anime-style swarming missiles. He'd be a like a mobile squad-level point defense station.
i'd hit it so hard, if you pulled me out you'd be the king of britain [bash.org]
Indeed, that's an excellent reason why armored vehicles (like tanks) are no longer used in modern armies: a single hit into a vulnerable part can disable them. You don't use anything that is not completely, 100% perfect. Never mind that a single land-bound tank, while it lasts, can break through defenses that otherwise would be impenetrable. There simply would be no military value in a tank that can run, climb, jump - even if it has some limited flight capability. Just think of it, what if it gets destroyed while doing its job?
