The U.S. Food and Drug Administration has given clearance to market and sell the powered lower-limb exoskeleton created by a team of Vanderbilt engineers and commercialized by the Parker Hannifin Corporation for both clinical and personal use in the United States. "I'm really glad," said H. Fort Flowers Professor of Mechanical Engineering Michael Goldfarb who developed the exoskeleton with a team of engineers and students in his Center for Intelligent Mechatronics.
