The Topic for Today is:

So, rather than reduce the soldier's load, is this going to be our solution?

Given that it takes 24+ AA batteries a day to power up the stuff the current grunt has to schlep around with him, what's this going to do to the current Logistician's Nightmare?

I have to go Data Diving, talk amongst yourselves....

Ultimately intended to help people like soldiers or firefighters carry heavy loads for long distances, these boots are made for marching.

"The design of this exoskeleton really benefits from human intellect and the strength of the machine," says Homayoon Kazerooni, who directs the Robotics and Human Engineering Laboratory at the University of California-Berkeley.

The exoskeleton consists of a pair of mechanical metal leg braces that include a power unit and a backpack-like frame. The braces are attached to a modified pair of Army boots and are also connected, although less rigidly, to the user's legs.

More than 40 sensors and hydraulic mechanisms function like a human nervous system, constantly calculating how to distribute the weight being borne and create a minimal load for the wearer.

"There is no joystick, no keyboard, no push button to drive the device," says Kazerooni, a professor of mechanical engineering. "The pilot becomes an integral part of the exoskeleton."

In lab experiments, says Kazerooni, testers have walked around in the 100-pound exoskeleton plus a 70-pound backpack and felt as if they were carrying just five pounds.

The whole thing is here, with a link to some interesting video.

From an engineering/design point-of-view, this looks interesting and should be pursued. However, unless the project has realisticly objective goals, such as "exoskeleton weight not to exceed 20% of maximum load, which shall not exceed 40% of body weight", or "minimum battery life at max drain rate will exceed 24 hrs", this project will be a Comanche/Crusader repeat. In other words, the people supervising project requirements need to be reminded the the goal is "to improve the soldier, not advance the technology." Right now this appears to be aiming at a product which will improve the performance of hodcarriers. Cheers JMH
 
Looks like the repair bay on the "Roger Young" The novel, not that stupid movie. Call me Heinlein guy. MonkeyPants
 
I'm with CPT Heinrichs here. Interesting concept and I have no doubt that it (or something like it) will one day be part of the REAL Mobile Infantry's equipment. But until the points that CPT Heinrichs mentions have been addressed, it's nothing but a fancy hi-tech prototype.
 
Hmmm... back in the 1960s, there was an Air Force project called "Man Amplifier" which looked remarkably similar. I believe they shelved it when they couldn't figure out how to power it reliably. Realizing that there has been considerable progress in power source tech since then, I'd still be very cautious about fielding a pile of moving parts like that and trying to keep it running under adverse conditions. (What do you do if you're out in BFE with 300 pounds of badly-needed supplies strapped to your exoskeleton and the fuel cell fries? Call AAA?) Back in 1917, Horace Kephart detailed a 42-pound autumn hunting kit (including a weeks' provisions) in his work "Camping and Woodcraft." (He also mentions a _seven pound_ bicycle camping kit.) Given the advances in lightweight materials, transport and weapons technology we have today, you have to ask the question that will get you into the most trouble: "What is it for?"
 
Ah, ref Mr Kephart: his lightweight pack weighed 18lb 3oz for the camping gear, plus 4lb 15oz of food for two days, a total of 23lb 2oz. His estimated pack weight for a one week trip was 35.5lb (Camping and Woodcraft, Vol II, pg 105-107). Maj N.V. Lothian, in "The Load Carried by the Soldier"(1923), established that the optimum load was 25-33% of the soldier's weight, with 40% as the never-exceed maximum. His data was derived from a variety of sources, beginning with the Roman Army through to WW1. Part of his arguement uses data from tests by the Prussian Army post-Franco-Prussian War. Note that the referenced 'soldier's weight' was "naked, unclothed". Gen S.L.A. quotes Maj Lothian extensively in his "Soldier's Load and the Mobility of a Nation". Cheers JMH (UFIO)
