Wearable Robots Design

Robotics inventor Stephen Jacobsen demonstrates an exoskeleton design that provides superhuman strength.
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. It's a daring vision-and Sarcos is hardly the first group to pursue it-but Jacobsen seems a good bet to do it right. Over the course of his career, the prolific inventor has developed standout devices that include the world's leading powered prosthetic arm and the dancing fountains of the Bellagio hotel in Las Vegas-all using the most advanced robotics technologies available. And while it may take years to make exoskeletons practical for widespread use, Jacobsen says, "before you do it right, you have to do it at all."
