Metal-Less Motor Runs on Air and Light

A new motor made out of plastic, ceramic and rubber, driven by air, and controlled by light has been created by the Johns Hopkins Urology Robotics Lab. Because the motor contains no metal and doesn't rely on electrical signals, remote controlled robots can be constructed which can operate within an MRI during medical procedures. The result will be precision movements as fine as 50 micrometers which should improve results for delicate tumor removal and tissue sample collecting procedures.
