Researchers from the University of Texas have given birth to the robot jellyfish -- or, 'Robojelly' -- and the sea critter can theoretically live forever as long as it's underwater.
It is made of artificial muscles and, as shown in the video, moves quite gracefully when in water. This invention could be used for various underwater endeavors, from entertainment to military missions. It acts just as a jellyfish would by the way it maneuvers through water. From afar, the robot jellyfish would blend in perfectly with sea life and fool any avid water watcher. The above video depicts Robojelly in a water tank and opens doors for robots that can power themselves through self-sustaining electricity.
