A new exoskeleton developed by Lockheed Martin could work wonders for troops carrying heavy loads. The Fortis exoskeleton system lessens leg strain and makes it easier for soldiers to carry heavy loads without becoming exhausted.



According to Army Technology, a study by the University of Michigan Human Neuromechanics Laboratory found that people equipped with the Fortis leg exoskeleton carrying a 40-pound load at a 15-degree angle experienced significantly less leg strain.

The knee stress release device (KRSD) was designed to boost leg capacity when lifting or dragging heavy objects, or walking on inclines. The exoskeleton then generates synchronized movements at the motorized knees that physically aid the wearer. It weighs 27 pounds, but Lockheed says the weight is so well-distributed the wearer barely notices it. Lockheed Martin claims the system improves work rates by “2 to 27 times”, and that it requires a minimum of training to use.

The exoskeleton system has serious implications for the future of ground warfare. Soldiers equipped with the devices can carry more supplies, all the more important in an era when the U.S. Army believes its units may have to operate on future battlefields cut off from regular sources of supply.

As a result, soldiers can stand carrying heavy weapons longer—think shoulder-fired Stinger anti-aircraft missiles and other heavy weapons. Soldiers could also traverse difficult, hilly terrain in places like Afghanistan and Korea with less exertion.
