The once futuristic Iron Mans robotic suite from Marvel is no longer just fiction. Development has in this area finally caught up with science fiction thanks to the complete robotic exoskeleton for humans, XO2, developed by the company Raytheon. And it actually seems to work, even thou the tethered version seems to be the first one available, and the flying version will have to wait a decade or two.
This, and similar products like the robotic legs from Honda, will be a useful tool in industries with heavy lifting, long term loads and perhaps even offshore industry. Unfortunately the first place these complete robotic suits will be seen is in military situations.
