"Stories about superhuman strength permeate popular culture from Atlas to Zeus, Superman to Schwarzenegger. But now, says University of Utah robotics expert Stephen Jacobsen, it's time to deliver in the real world. With funding from the U.S. Department of Defense, Jacobsen's Salt Lake City-based company, Sarcos, has built a robotic suit that does just that. A person wearing this powered 'exoskeleton' on his or her legs can carry massive loads without getting tired. Exoskeletons could enable soldiers to haul heavier equipment over greater distances, allow rescue workers to carry survivors more safely, and eventually help disabled people get around."I mean, if the exoskeleton becomes affordable, how many lazy people will buy them?
