Robotic jellyfish runs off renewable energy

“We’ve created an underwater robot that doesn’t need batteries or electricity,” said Yonas Tadesse, assistant professor of mechanical engineering at the University of Texas, and one of the study’s authors, in a statement about the research. “It feeds off hydrogen and oxygen gasses and the only waste released as it travels is water.”

Summary: Researchers at the University of Texas (Dallas) and Virginia Tech experiment with a robot that runs of hydrogen and oxygen.

Researchers at the University of Texas at Dallas and Virginia Tech are using the concept of biomimicry to experiment with a robot that could, in the future, provide a model for the design of undersea surveillance and rescue vehicles.

So far, researchers have applied their approach to a robotic jellyfish (see the video below for a demonstration). The robotic jellyfish uses hydrogen and oxygen gasses in water as its source of energy. The work is described in Smart Materials and Structures.
