Nov. 25 (UPI) -- Scientists have developed a small four-winged robot that flies through the air much the way a jellyfish swims in water.
Created by Leif Ristroph of New York University, the flying robot has four wings around it's waist which move up and down just 20 times per minute, and resemble the pulsating movement of a jelly fish. The robot weighs just two grams and is four inches across.
