WIESBADEN, Germany -- Army veteran Dr. Rory Cooper shows off medical rehabilitation robotics technologies Oct. 1, 2018, at the Mission Command Center on Clay Kaserne. Cooper has worked extensively to assist veterans via joint collaborations between the Veterans' Affairs at the University of Pittsburgh and Walter Reed National Military Medical Center. His pneumatic chair is completely powered by compressed air and therefore completely submersible, making it ideal for the beach or water park. The yellow and black chair moves in all directions, as well as forward to help a user get out of the chair. A handcycle is custom fitted to Cooper's body and very light weight due to its carbon fiber construction.
