Here is an article about the Raytheon Sarcos robot exoskeleton. The article states that they are just 5 years from production. I posted a blog post about two years ago on their work. So this means that they have come pretty far in terms of progress. Raytheon's second-generation exoskeleton (XOS 2), essentially a wearable robotics suit, was unveiled for the first time recently during an event at the company's Salt Lake City research facility. XOS 2 is lighter, stronger and faster than its predecessor, yet it uses 50 percent less power, and its new design makes it more resistant to the environment.
The wearable robotics suit is being designed to help with the many logistics challenges faced by the military both in and out of theater. Repetitive heavy lifting can lead to injuries, orthopedic injuries in particular. The XOS 2 does the lifting for its operator, reducing both strain and exertion. It also does the work faster. One operator in an exoskeleton suit can do the work of two to three soldiers. Deploying exoskeletons would allow military personnel to be reassigned to more strategic tasks. The suit is built from a combination of structures, sensors, actuators and controllers, and it is powered by high pressure hydraulics.
Representatives from Paramount Home Entertainment, including the actor Clark Gregg (aka Agent Phil Coulson of the Marvel® Movie franchise) were in attendance to capture footage of XOS 2 to include in a video that's being produced to support the release of Iron Man® 2 on DVD and Blu ray.
