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 study of robotic fish and underwater vehicle dynamics presents a fascinating convergence of biomimetics and fluid mechanics. Drawing inspiration from the streamlined efficiency and manoeuvrability ...

Add Yahoo as a preferred source to see more of our stories on Google. Underwater vehicles haven’t changed much since the submarines of World War II. They’re rigid, fairly boxy and use propellers to ...

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 ...

A coil-powered robot fish designed by scientists at the University of Bristol could make underwater exploration more accessible. The robot fish was fitted with a twisted and coiled polymer (TCP) to ...

Underwater vehicles haven’t changed much since the submarines of World War II. They’re rigid, fairly boxy and use propellers to move. And whether they are large manned vessels or small robots, most ...

The deepest regions of the oceans still remain one of the least explored areas on Earth, despite their considerable scientific interest and the richness of lifeforms inhabiting them. Two reasons for ...
