Scientists have produced a robot that looks just like a jellyfish for the U.S. Navy with funding from the Office of Naval Research. This foot-long submarine will most likely perform spy missions running on seawater.

Dubbed as “Robojelly,” a submarine drone, it is fueled by hydrogen and oxygen in the water was invented by researchers from The University of Texas at Dallas and Virginia Tech.

This week they reported their robot jellyfish findings in the academic journal, “Smart Materials and Structures.”

“We’ve created an underwater robot that doesn’t need batteries or electricity,” said Dr. Yonas Tadesse, assistant professor of mechanical engineering at the University of Texas and lead author of the study. “The only waste released as it travels is more water.”

Those working on inventions for the military have increasingly been gearing toward the animal kingdom when creating brand new technology, with creatures such as jellyfish or insects.

For example, the Scientists at the Defense Advanced Research Projects Agency, or DARPA, are pursuing new ways of creating insect cyborgs, by embodying mechanical elements into larvae and then employing them to conduct the mature insect when it transpires.

“It could stay underwater and refuel itself while it is performing surveillance,” stated Dr. Tadesse.
