Super Soldier Suit

Robotic suit could usher in super soldier era

Rex Jameson bikes and swims regularly, and plays tennis and skis when time allows. But the 5-foot-11, 180-pound software engineer is lucky if he presses 200 pounds—that is, until he steps into an "exoskeleton" of aluminum and electronics that multiplies his strength and endurance as many as 20 times. With the outfit's claw-like metal hand extensions, he gripped a weight set's bar at a recent demonstration and knocked off hundreds of repetitions. Once, he did 500.

"Everyone gets bored much more quickly than I get tired," Jameson said.
Jameson—who works for robotics firm Sarcos Inc. in Salt Lake City, which is under contract with the U.S. Army—is helping assess the 150-pound suit's viability for the soldiers of tomorrow. The suit works by sensing every movement the wearer makes and almost instantly amplifying it.
The Army believes soldiers may someday wear the suits in combat, but it's focusing for now on applications such as loading cargo or repairing heavy equipment. Sarcos is developing the technology under a two-year contract worth up to $10 million, and the Army plans initial field tests next year.
Before the technology can become practical, the developers must overcome cost barriers and extend the suit's battery life. Jameson was tethered to power cords during his demonstration because the current battery lasts just 30 minutes.
But the technology already offers evidence that robotics can amplify human muscle power in reality—not just in the realm of comic books and movies like the recently debuted "Iron Man," about a wealthy weapons designer who builds a high-tech suit to battle bad guys.
"Everybody likes the idea of being a superhero, and this is all about expanding the capabilities of a human," said Stephen Jacobsen, chief designer of the Sarcos suit.
The Army's exoskeleton research dates to 1995, but has yet to yield practical suits. Sarcos' technology sufficiently impressed Raytheon Co., however, that the Waltham, Mass.-based defense contractor bought Sarcos' robotics business last November. Sarcos also has developed robotic dinosaurs for a Universal Studios' "Jurassic Park" theme park ride.
Jack Obusek, a former colonel now with the Army's Soldier Research Development and Engineering Center in the Boston suburb of Natick, foresees robot-suited soldiers unloading heavy ammunition boxes from helicopters, lugging hundreds of pounds of gear over rough terrain or even relying on the suit's strength-enhancing capabilities to make repairs to tanks that break down in inconvenient locations.
Sarcos' Jacobsen envisions factory workers someday using the technology to perform manual labor more easily, and firefighters more quickly carrying heavy gear up stairwells of burning buildings. Disabled people also may find uses for the technology, he said.
"We see the value being realized when these suits can be built in great numbers for both military and commercial uses, and they start coming down in cost to within the range of the price of a small car," said Jacobsen. He declined to estimate how much the suit might cost in mass production.
But cost isn't the only obstacle. For example, developers eventually hope to lengthen the suit's backpack battery's life and tinker with the suit's design to use less energy. Meanwhile, the suit can draw power from a generator, a tank or helicopter. And there are gas engines that, while noisy, small enough to fit into the suit's backpack.
"The power issue is probably the No. 1 challenge standing in the way of getting this thing in the field," Obusek said.
But he said Sarcos appears to have overcome the key challenge of pairing super-fast microprocessors with sensors that detect movements by the body's joints and transmit data about them to the suit's internal computer.
Much as the brain sends signals to tendons to get muscles to move, the computer sends instructions to hydraulic valves. The valves mimic tendons by driving the suit's mechanical limbs, replicating and amplifying the wearer's movements almost instantly.
"With all the previous attempts at this technology, there has been a slight lag time between the intent of the human, and the actual movement of the machine," Obusek said.
In the demonstration, the bulky suit slowed Jameson a bit, but he could move almost normally. When a soccer ball was thrown at him, he bounced it back off his helmeted head. He repeatedly struck a punching bag and, slowly but surely, he climbed stairs in the suit's clunky aluminum boots, which made him look like a Frankenstein monster.
"It feels less agile than it is," Jameson said. "Because of the way the control laws work, it's ever so slightly slower than I am. And because we are so in tune with our bodies' responses, this tiny delay initially made me tense."
Now, he's used to it.
"I can regain my balance naturally after stumbling—something I discovered completely by accident."
Learning was easy, he said.
"It takes no special training, beyond learning to relax and trust the robot," he said.

Super Soldier Technology

July 16, 2008

$3 billion super soldier program: 10 times muscle endurance, 7 foot vertical leap, wall crawling, personal flight and more

DARPA today has a long-term, $3 billion program to help make such a “Metabolically Dominant Soldier.” In other words, the military is studying how to use technology and biology to meld man and machine and transcend the limits of the human body. Described the project director, “My measure of success is that the International Olympic Committee bans everything we do" The $3 billion program is definitely trying to achieve transhuman performance goals.

The wearable gear would enable running at 100 meter olympic sprinter speed for hours and the 7 foot vertical leap, the wall crawling, personal flight, invisibility, greatly enhanced strength, better body armor and carrying bigger and more powerful weapons.

UPDATE: Advanced gene therapy could provide cheetah or gorilla quality muscles in people for 45 mile per hour speed or five to ten times strength

There are suitable engines for powering the exoskeleton described in this article

END UPDATE

The drugs and genetic enhancements and some technology which gets applied would allow for regeneration, faster healing, muscle strength enhancement up to current olympic levels, endurance of an Alaskan sled dog, cognitive enhancement, operate without sleep for many days without performance degradation, the metabolic energy of twenty year old for a forty or fifty year old and immunity to pain.

The Metabolically Dominant Soldier program is managed by Joe Bielitzki. He is talking about fixing your cells so that you could live off your fat. Bielitzki acknowledges the potential for spin-off technologies. “Forty billion dollars a year goes into the weight loss industry in this country,” he muses. “This will change it.”

Regeneration, better healing, better immune systems would all revolutionize healthcare costs and healthcare effectiveness. So trillions in economic benefit as a side effect of supersoldier success. DARPA is also trying to enhance cognition, training and giving the energy levels of youth to the elderly. Those could provide multi-billion or even trillion dollar per year boosts to the US and world economy.

Projects in pipeline range from drugs that will boost muscles and energy by a factor of 10, akin to steroids…on steroids (the project is jokingly termed the “Energizer Bunny in Fatigues”) to wearable, cooling gloves that regulate body temperature and prevent soldiers from getting overheated (and thus tired) even on the hottest desert day. [Keeping the body cool increases endurance]

This program is going well beyond some current relatively safe and conservative forms of performance enhancement. [Safer SARM/steroids, endurance enhancing drink]

A major focus is on helping the soldier’s body to better deal with trauma and damage. One such is the “pain vaccines” coming out of a program at Rinat Neuroscience [Pfizer acquired Rinat Neuroscience in 2006]. Researchers are hopeful these “will block the sense of pain for almost a month,” describes DARPA’s Michael Goldblatt.

The substance does is block intense pain in less than 10 seconds. Its effects last for 30 days. It doesn’t stifle your reactions. If you touch a hot stove, you still have the initial shock; your hand will still automatically jerk away. But after that, the torment is gone. The product works on the inflammatory response that is responsible for the majority of subacute pain. If you get shot, you feel the bullet, but after that, the inflammation and swelling that trigger agony are substantially reduced. The company has already hit its first milestones in animal testing and is preparing reports for scientific conferences.

Army Soldier enhancement systems

The plan is for new body armor that, instead of Kevlar, is filled with nano-materials that are connected to a computer. [Computer controlled liquid armor] It would normally be as flexible as regular uniform made of fabric. But, like how a crash-bag works inside a car, it would activate whenever the system detects a bullet strike and turn as hard as steel in an instant.

Gloves could turn into real-life brass knuckles.

The fabric could even be woven in with "nanomuscle fibers" that simulate real muscles, giving soldiers more an estimated "25 to 35 percent better lifting capability." So myostatin strength boost to get to olympic athlete strength levels and then 25-35% boost from a soft suit. Use better exoskeletons for more strength enhancement.

From deflecting bullets to powers of invisibility, as military analyst Max Boot writes, such a suit truly “would give ordinary mortals many of the attributes of comic book superheroes.


Our wimpy little Achilles tendons allow the average human to run somewhere between 6 to 8 miles an hour and, unless your name is LeBron James, leap only a few feet in the air. New “bionic boots” and “spring walkers” in development are hoped to solve this. These attach outside the leg and mechanically mimic the enlarged Achilles tendon of a kangaroo, one day perhaps giving the wearer the ability to run as fast as 25 miles per hour and leap 7 feet.

The Mesoscopic Integrated Conformal Electronics (MICE) program has already succeeded in printing electronic circuits on the frames of eyeglasses and helmets, weaving them into clothes, even putting them on insects. These include electronics, antennas, fuel cells, batteries and solar cells.

The Biological Input/Output Systems program is designed to enable plants, microbes and small animals to serve as “remote sentinels for reporting the presence of chemical or biological” particles. They’d do this by changing color, lighting up fluorescently, dropping their leaves or changing the color of their flowers.

The Brain-Machine Interface program is investigating how you would put wireless modems into people’s skulls.

And that’s just the Defense Sciences Office, the department of DARPA most directly involved with human enhancement. Meanwhile, on the floor where the Information Processing Technology Office (IPTO) resides, its director, Ron Brachman, former research vice president at AT&T Labs and previously at Bell Labs, and president of the American Association for Artificial Intelligence, wants to complete DARPA’s vision from the sixties. When the original IPTO was created in 1962, its director, J.C.R. Licklider, focused the office on his novel conception of computers and humans working in symbiosis. That idea resulted in the Internet. Now the new IPTO “wants to realize this vision by giving computing systems unprecedented abilities to reason, to learn, to explain, to accept advice, and to reflect, in order to finally create systems able to cope robustly with unforeseen circumstances,” according to Brachman. The object of the game is to produce machines—and the italics are his—“that truly know what they’re doing.

A project is regarded as "DARPA-esque" only if few others would tackle it, but it would be earth-jolting if it did work. DARPA's attitude is if an idea looks like a sure thing, let somebody else fund it. The “special focus area” is for really extreme projects.

Darpa supports the Raytheon Sarcos XOS exoskeleton

Of the three teams that took part in a seven year $75 million project (Sarcos, Oak Ridge National Laboratory, and the University of California at Berkeley), the XOS emerged in 2005 as the suit closest to the agency's initial vision. It is the only full exoskeleton the military has moved into the next development stage; Sarcos is now working under a two-year, $10-million Army grant.


During XOS demos the suit is tethered to a hydraulic pump that draws electricity from an external power supply. The suit can operate from batteries, but only for 40 minutes at a time.

The country's other two top exoskeleton designers, Massachusetts Institute of Technology professor Hugh Herr and Homayoon Kazerooni of the University of California at Berkeley, began with the power problem.

Herr is trying to build a leg-powering machine that uses as little energy as possible—the first iteration draws a mere two watts, comparable to a portable radio—but can support 80 percent of an 80-pound load on a user's back. Herr thinks that within the near future, he can improve the mechanics so that the machine actually saves the wearer effort.

Kazerooni has made the Human Load Carrier (HULC) which is a lower-body exoskeleton that can operate for more than 20 hours without recharging. He says it allows the user to carry 100 pounds on his back and burn 15 percent less oxygen than if he was supporting the added weight alone. A three-year, $2-million grant from the National Institute of Standards and Technology is being used to modify as a wheelchair replacement.


The army is now performing live fire tests of new body armor

Currently : the Army issued the Improved Outer Tactical Vest, a redesigned version of Interceptor body armor, starting in late 2006. The soft body armor protects against 9mm ammunition and fragmentation. IOTV is also equipped with front, rear and side armor plates known as Enhanced Small Arms Protective Inserts. When worn together, the IOTV will stop 7.62mm armor-piercing rounds.

Several vendors have demonstrated they can produce body armor that can outperform the protection offered by IOTV with ESAPI.

The Land Warrior system was sent in to battle in spring 2007 with the 4th Battalion, 9th Infantry Regiment, 4th (Stryker) Brigade, 2nd Infantry Division. At that time the deployed system weighed 10 pounds (down from 17 pounds). The weight has been dropped to seven pounds, and they expect to reduce it even further.

Program Executive Office (PEO) Soldier was created by the Army with one primary purpose: to develop the best equipment and field it as quickly as possible so that our Soldiers remain second to none in missions that span the full spectrum of military operations. PEO soldier currently has 400 programs.

The Soldier Enhancement Program (SEP) is to identify and evaluate commercially available individual weapons, munitions, optics, combat clothing, individual equipment, water supply, shelters, communication and navigational aids which can be adopted and provided to Soldiers in three years or less.
