Engineers have created a mechanism that teaches robots to move like fish

Researchers from the University of Nice – Sophia Antipolis (CNRS) have unveiled a new bioinspired mechanism that will allow robots to swim like fish.

Over the past few decades, engineers have developed many robots inspired by both humans and animals. However, in order to effectively mimic living organisms, mechanisms must not only be like them; they must also move in the same way.

French researchers have unveiled a new bioinspired mechanism that helps robots swim like fish. It is based on proprioception – the ability of animals to collect information about the position, movement and acceleration of their bodies. The research results are published in the journal Physical Review Letters.

The main advantage of the proprioceptive mechanism presented by scientists is that it allows robotic swimmers to adapt their movement to their environment, as fish do. In fact, most fish have lateral natural “sensors” that measure the pressure of fluid on the body, allowing them to integrate proprioceptive senses.

The researchers tested their proprioceptive mechanism on a real biomimetic robot. Using it, the robot floated in the water like a fish.
