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 ...

Researchers at Michigan State University's Smart Microsystems Lab have been developing robotic fish for several years, and the most recent incarnation can glide long distances, as well as swim by ...

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 ...

Underwater vehicles are typically designed for one cruise speed, and they’re often inefficient at other speeds. The technology is rudimentary compared to the way fish swim well, fast or slow. What if ...

An invention born from a contest at England's University of Surrey might be swimming us closer to cleaner oceans. Researchers have created a robotic fish that doesn’t just collect plastic pollution; ...

A coil-powered robot fish could make underwater exploration more accessible. A coil-powered robot fish designed by scientists at the University of Bristol could make underwater exploration more ...

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 ...
