Plenty of companies are working on perfecting exoskeletons that can help workers and disabled people do things with less effort. HERCULE is an exoskeleton that can fit a wide variety of body sizes and carry heavy loads over several kilometers. This new version is easier to use than the previous version and has half the weight.
HERCULE V4 works on a wide variety of surfaces. It runs smoothly for 3 hours. More info is available here.
