US Army Furthers Development of Robotic Suits

An anonymous reader writes "The BBC reports on advancements in the US military's robotic exoskeleton program. It's being spearheaded by Sarcos, a research laboratory in Utah. The firm has designed the XOS exoskeleton for US Army use, a lightweight frame that gives the user greater strength and endurance. 'With the exoskeleton on and fully powered up, Rex can easily pull down weight of more than 90 kilos, more than he weighs. For the army the XOS could mean quicker supply lines, or fewer injuries when soldiers need to lift heavy weights or move objects around repeatedly. Initial models would be used as workhorses, on the logistics side. Later models, the army hopes, could go into combat, carrying heavier weapons, or even wounded colleagues.'"

So, it's official, we're nearly ready for "aliens"

Seriously, this is a good thing but I think some of the 'planned' uses are a bit optimistic. I'm more than willing to be surprised though.

Anything with useful commercial life would need power like a forklift, and that is about as small as you can make a useful 'suit' for lifting that is self powered.

Who knows, maybe granny will walk again one day soon. What we do know is that she won't get to compete in the olympics with her new suit!

Won't somebody think of the illegal immigrants? This thing could put the day laborers out of work.

No car analogy yet... forklift was as close as I could get :)

I wonder though

[hey!]

Why a suit, instead of an armed, semi-autonomous ROV? Why spend weight (and thus battery) protecting the squishy bits inside, when those bits can back home at an army base working eight hour shifts and going home to their families?

I realize that troops have to carry an ungodly amount of gear, but by the time all the technical challenges of a truly battle-ready suit are met, surely putting a person in it would be a waste.

Because the meat inside gives it decision making capabilities that cannot be matched by AI either now or in the foreseeable future.

Also because the human body is remarkably flexible in its movement and our brains are evolved to be quite good at this type of movement. An augmentation system doesn't have to necessarily PROTECT the wearer - that's what armour is for. It's about enhancing the natural strength of the soldier, who is still one of the most effective weapons in nearly all combat situations. The ability to lift heavier objects (weapons, for instance), and presumably to throw things like grenades further will be useful.

I did find it amusing that the first uses are hoped to cause "fewer injuries when soldiers need to lift heavy weights or move objects around repeatedly". Not much of a combat objective!

Re:I wonder though

OK, I'm playing devil's advocate here.

Is the human form really the ideal form for urban warfare? Why not a swarm of robotic bees with taser stings? Furthermore, you aren't restricted to one form factor. You can have robotic spy-flies, robotic sapper-rats, robotic wall battering elephants.

It's not that I can't imagine a force of power armored commandos that can do things that normally equipped ones cannot. It's that I can't imagine the technology that makes that practical not creating even better choices.

Re:Why bother?

[AHumbleOpinion]

Lifting stuff, we have forklifts for that. Much simpler and cheaper.

Really, you've seen many forklifts in the field unloading Hueys or Blackhawks, or unpacking a palette from a Chinook or Hercules?

Heavy weapons? Is the US military's problem really a lack of firepower? I seriously doubt it.

OK, you obviously never saw the guy carrying the M60 and its ammo.

What terrain would be suitable for powered suits?

[TheHawke]

Here's that ages-old question: Where are you going to be able to safely and efficiently operate a powered suit without sinking up to your waist in muck, tipping over due to unstable or uneven terrain, and be able to lift a working payload at the same time.

'Suits have this problem called weight distribution. Their footprints are about on par with a small car overloaded. When try to move loads on poor terrain, you'll wind up either getting dug out or being picked back up because the soil could not hold you up. Tracks that can handle twice their load can dance on that kind of terrain, even BobCats with tracks can handle soft sands that would try to swallow an average joes' foot.

I can see powersuits working on prepared grounds, Asphalt, cement concrete, macadam with treated substrates, but not thrown into a active combat situation where they would have to slog through mud or soft soils.
