American Soldiers Test Battery-Powered Exoskeletons

23.09.2015 | IEEE Spectrum | spectrum.ieee.org

Deep in the woods in Maryland, the U.S. Army is testing exoskeletons that can lighten the load that soldiers carry.

Soldiers often have to hike extended distances while carrying heavy packs and equipment. This soft, lightweight exoskeleton takes on some of that weight, reducing the burden on a soldier’s body. It uses a system of powered cables to provide mechanical assistance, adding carefully timed pulling forces to natural movements so that the user’s own muscles expend less energy.

American soldiers testing new exoskeletons

Harvard’s exoskeleton prototype is undergoing performance testing by the U.S. Army Research Laboratory (ARL) at Aberdeen Proving Ground in Maryland. Soldiers wear the prototype underneath a full set of battle gear and hike a three mile course, including roadways and moderately rugged, wooded terrain. ARL technicians monitor the soldiers’ stride lengths and frequency, muscle activity, and energy expenditure. The goal is to allow soldiers to walk longer distances carrying heavy loads with less effort, while also minimizing risk of injury.
