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 ...

Beneath the ice of Antarctica’s Weddell Sea, scientists discovered a vast, organized city of fish nests revealed after the ...

Researchers from Cornell University and the University of Pennsylvania have created a lifelike robotic lionfish with a circulatory system, reports Gizmodo. That circulatory system enables the fish to ...

In an effort to create more autonomous, life-like robots, scientists have developed a soft robotic lionfish with a multi-functional circulatory system. A blood-like compound powers the bot and ...

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 ...

This plastic-eating, self-powered robotic fish could mark the beginning of a new era in environmental cleanup, in which technology doesn’t just consume energy but gives some back to the planet.

For environmental researchers, using robots to collect much-needed water samples can be tricky. The bot might have trouble navigating around trash while collecting samples from polluted waters, for ...

Mosquitofish may look small and unassuming, but don't let appearances fool you: these invasive fish are menaces. Outside of their range, they outcompete other freshwater critters—like fishes and ...

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 ...

A bio-inspired robot can use water from the environment to launch itself into the air, British researchers revealed. The robot can travel 85 feet through the air after taking off and researchers ...
