American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fueled by hydrogen.
Scientists working with the United States Navy have built a new robotic jellyfish that acts as a submarine. The researchers at the University of Texas at Dallas and Virginia Tech say that “Robojelly” may soon be used on spy missions.
“We’ve created an underwater robot that doesn’t need batteries or electricity,” Dr. Yonas Tadesse, assistant professor of mechanical engineering at the University of Texas said, according to The Washington Times. “The only waste released as it travels is more water.”
“Robojelly” runs on hydrogen and oxygen in the water it flows through. It is made up of a rubber silicone dome that expands and contracts, mimicking the movement of an actual jellyfish. Heat-sensitive wires control its movement; they heat up when in contact with hydrogen and oxygen, pulling on strings inside the dome and causing it to contract and expand.
