Raytheon XOS 2 Suit -- The Real Iron Man 2

Real-life Iron Man suit is better than predecessor

Second-generation exoskeleton robotic suit developed for the military unveiled

A new second-generation exoskeleton robotic suit developed for the military – and deemed the closest thing to a real-life Iron Man costume – was unveiled on Monday during a demonstration with Paramount Home Entertainment. 

The new robotic suit called Exoskeleton (XOS 2) – released by Raytheon Company – is lighter, faster and stronger than its predecessor, yet it uses 50 percent less power. Its enhanced design also means that it is 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.

The 95-kilogram XOS 2 is about 40 percent stronger than its 88-kilogram predecessor—the XOS-1 could lift about 16 kilograms with each arm, XOS-2 can lift about 23 kilograms.
Reduced power consumption is key to making the exoskeleton practical to the military. The system is powered by an internal combustion engine, and its electrical systems are run by a wire that tethers the XOS 2 to a power source. Raytheon decided not to use batteries because the company's engineers didn't trust the safety of Lithium-ion batteries in close proximity to the person wearing the exoskeleton.
