USA Today has an article about how Robotic devices are helping the paralyzed. Professor Eamon Doherty and some of his graduate students at Fairleigh Dickinson University are testing robotic arms and legs for people who are paralyzed and don't have use of their own arms and legs. Using radio sensors to pick up minute radio electronic signals from nerve cells, the robotic arms and legs can move via the operator's own nervous system electronic signals. Those who were once paralyzed are now able to feed themselves, paint, and other fantastic achievements. Only simple commands can be made right now, but perhaps someday these robotic arms and legs may be made to perform like real ones and move solely on commands from the brain!
