Starfish inspire new generations of robots that can adapt to physical injuries


Researchers at Tohoku University and Hokkaido University have for the first time succeeded in developing a robot that instantly adapts to physical damage. surprise.

This is an important breakthrough because robots will be increasingly quality and sustainable to operate in harsh environments with many dangerous conditions.

Starfish inspire new generations of robots that can adapt to physical injuries

Conventional robots tend to require a considerable amount of time (several tens of seconds) to adapt when they are subject to sudden physical damage. To solve this problem, researchers led by Professor Akio Ishiguro of the Institute of Electronic Communications Research at Tohoku University focused on studying a starfish species with five flexible tentacles. This starfish lacks a sophisticated central nervous system, but it can instantly adapt to losing tentacles and still move by coordinating the remaining tentacles.

Based on behavioral experiments involving starfish whose tentacles have been cut in several ways, the researchers devised a simple decentralized control mechanism in which each arm only operates on the ground. when it gets the reaction force. This mechanism can be applied in a robot to help it adapt to unexpected physical damage within seconds, just like the starfish’s biological model.

The researchers hope that the discovery will help them develop complete robots that can operate in harsh environments such as disaster areas. It also provides insights into the essential mechanism of engine corrosion during motor.
