RoboKrill is a one-legged robot that mimics the way krill swim

A robot with appendages that mimic the swimming legs of krill could one day be used to study these key marine food sources or explore hard-to-reach places

Technology 15 February 2022

A robotic leg moving through water creates similar patterns to the motion of krill as they swim, and could be used to study the role these animals play in their marine environment.

Krill are small crustaceans that serve as one of the most important and abundant ocean food sources. They form large swarms on the ocean surface and dive down when threatened by predators, taking nutrients, carbon and oxygen with them, but the dynamics of this behaviour aren’t fully understood.

To better understand how krill move, Monica Martinez Wilhelmus at Brown University in Rhode Island and her colleagues built …
