Robot mother helps South Koreans prepare for birth

With South Korea's birth rate at its lowest ever, medical students are resorting to robots to practice bringing babies into the world.

Students regularly crowd around Noelle as she gives "birth." They take turns at monitoring her vital signs and at pulling the "baby" out of her body.

The newborn, also a robot, is equipped with lights on its hands and cheeks to indicate its health -- blue lights mean problems while pink lights signal all is ok.
