Mackintosh’s proposal was a simple drawing showing how the robot fish could swim through the water, its internal cavity opening and then compressing to force water over the gills in order to ...

The robot AgnathaX is modeled on the lamprey, a jawless, blood-sucking fish that's been largely unchanged by evolution for the past several hundred million years.

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 ...

This project aims to develop and test a new fish-inspired robot that minimizes undesirable inertial recoil found in traditional fish swimming, while being capable of achieving high speeds and ...

Ultimately, the fish was able to travel more than a body length per second. At that pace, the robot was remarkably efficient—per unit of muscle mass, its swimming speed was better than that of ...

Tiny, robotic fish powered by human heart cells suggest that scientists are getting closer to their goal of building replacement hearts from living tissue.
