When designing fish-like underwater robots, you want a means of propulsion which is both energy-efficient and reasonably speedy. A new tail-flapping system may fit the bill, paving the way for wider ...

The winner of the inaugural Natural Robotics Contest not only swims through the water like a real fish — it also helps combat pollution in the process. Created by University of Surrey chemistry ...

According to its developers, the UJIFISH robotic fish features a design that eliminates stress factors such as propellers and ...

Microplastics are tiny pieces of plastic, usually about 5mm or less in size. They often develop over time as plastic breaks apart into smaller chunks. Microplastics have emerged as a growing threat to ...

You’re a fish in the ocean. It’s 2023 and humans have begun deploying swarms of sentinel robot fish along the reef where you live that will monitor your environment, track pollution and collect ...

A robot that looks and swims like a largemouth bass is effective at preventing mosquitofish from devouring vulnerable tadpoles, according to a study published Dec. 16 by iScience. Considering ...

Fish have a sensory system known as the lateral line, which allows them to detect movements and pressure gradients in the water. Scientists have now given a robotic fish its own version of that system ...

Scientists have built a school of robotic fish powered by human heart cells. The fish, which swim on their own, show how lab-grown heart tissue can be designed to maintain a rhythmic beat indefinitely ...
