When the surgeon asks for an instrument, Penelope retrieves it from an instrument tray. The robot picks up the instrument with a special gripper and hands it to the surgeon. When finished, the surgeon simply lays the instrument down. Penelope then uses a vision system to locate the instrument and return it to the instrument tray.

The world’s first vision-guided, autonomous surgical robot. The Penelope system will save hospitals money and improve quality of care in the operating room.
