New Robot Fish can Perform Movements as Quick as live Animals

Engineers have designed a new robot fish that can perform a rapid body motion as good as original fish in the wild. Being able to incorporate same quickness and precision as live animal in a robot fish is a great achievement for the engineers at Massachusetts Institute of Technology. Now, the empowerment would help the robot fish avoid chances of collisions with so many things while swimming in water.

The fish is well capable of executing a 'C-turn' in about 100 milliseconds. Soft robots are known as machines that are powered by fluid flowing through flexible channels.

"As robots penetrate the physical world and start interacting with people more and more, it's much easier to make robots safe if their bodies are so wonderfully soft that there's no danger if they whack you", said Daniela Rus, Professor of computer science and engineering and Director of MIT's Computer Science and Artificial Intelligence Laboratory.

The robot's body is configured in such a way that it allows it to constantly deform its body. Carbon dioxide canister provides the fuel and allows the robotic fish to perform up to 30 escape maneuvers before getting finished.

The researchers behind the robotic fish said that their stint is a first step towards creating soft robots that are well capable of operating in human-centered environments. The aim of researchers is to create a new version of the robotic fish that can last up to a half-hour and enable it to use water to pump through the tubing fish's body to propel it.

Rus believes their study will also be helpful for wildlife scientists to conduct various researches. The study has showed that soft robots are more capable compared to hard robots for performing certain tasks.
