Defense contractor Raytheon has announced an updated version to the company’s Sarcos XOS exoskeleton suit that allows for armed forces people to do heavy duty activities and lifting with greatly reduced muscle fatigue. The new model, dubbed the XOS 2, features a lighter and stronger frame that uses up to 50 percent less power. According to Raytheon, “With XOS 2, we targeted power consumption and looked for ways to use the hydraulic energy more efficiently. That’s resulted in us being able to add capabilities while significantly reducing power consumption.” However, with those goals, the challenge is still to create an untethered system with a built-in battery pack rather than have the army be plugged up to the nearest wall socket when they want to use the XOS or XOS 2 systems.
