A new device developed at Stanford Biomechatronics Laboratory ccould help older people with walking difficulties step more quickly on daily tasks. The robotic boot – called an exoskeleton – has a motor that works with calf muscles to give the wearer an extra push. Its impact is personalized thanks to a machine learning based model that was trained through years of work. Treadmill tests habe shown int produces major energy savings and higher walking speeds. The ultimate aim is to help peopl,e with mobility problems.
