“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.
