University of Florida mechanical and aerospace engineering student J.D. Yamokoski, (left), shows how a robot shadows his movement by tracking an LED-lit patch attached to his thigh. The robot is intended to follow and shoot X-ray video of sufferers of orthopedic injuries as they walk, climb stairs, stand up from a seated position or pursue other normal activities – and maybe even athletic ones like swinging a bat. The chief researcher on the project is Scott Banks, (right), an assistant professor of aerospace and mechanical engineering.
