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
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.
