Sarcos Exoskeleton Bringing Iron Man Suit Closer To Reality

Ever wanted to become Iron Man? Here's some good news: Sarcos recently said that its second-generation exoskeleton robot suit, XOS 2, is now five years away from production. IEEE Spectrum contributor Susan Karlin writes:

The wearable robotics suit augments the operator's strength by using a system of high-pressure hydraulics, sensors, actuators, and controllers to bear the weight of an object, while leaving its wearer agile enough to kick a soccer ball. It's also lighter, stronger, and more environmentally resistant, and it uses half the power of the company's first exoskeleton, XOS 1, which rolled out in 2008. The XOS 2 has been nicknamed the Iron Man suit in homage to the high-tech power suit in the comics and movies.

We first wrote about the Sarcos exoskeleton more than five years ago, when it was just a prototype developed as part of a DARPA program. Since then, Sarcos, now a division of U.S. defense contractor Raytheon, has significantly improved the device. The XOS 2 exoskeleton is designed to lighten a soldier's load and help the military reduce injuries. It also lets you pretend you're Tony Stark:

Several other companies and universities are developing exoskeletons to help not just soldiers but also the elderly and other people who might need assistance to walk, climb stairs, and carry things around.

Most notably, Japanese firm Cyberdyne has created a robot suit called Hybrid Assistive Limb, or HAL, which is commerciallyavailable in Japan. Automaton writer Evan Ackerman tested the HAL system at CES in January, becoming the first man in the United States to try out the device.

Then there's U.C. Berkelely spinoff Berkeley Bionics, which last year introduced its eLEGS robotic exoskeleton, a very impressive system that is helping paraplegics to stand up and walk. The company is currently testing eLEGS with a select group of rehab centers, hoping to make it available for purchase in the next year or so.

By 2050, the global population aged 65 or more will be nearly double what it is today. The number of people over the age of 80 will triple, approaching half a billion. Supporting an aging population is a worldwide concern, but this demographic shift is especially pronounced in Japan, where more than a third of Japanese will be 65 or older by midcentury.

Toyota Research Institute (TRI), which was established by Toyota Motor Corp. in 2015 to explore autonomous cars, robotics, and “human amplification technologies,” has also been focusing a significant portion of its research on ways to help older people maintain their health, happiness, and independence as long as possible. While an important goal in itself, improving self-sufficiency for the elderly also reduces the amount of support they need from society more broadly. And without technological help, sustaining this population in an effective and dignified manner will grow increasingly difficult—first in Japan, but globally soon after.
