MIT unveils Robot Fish that’ll study sea creatures in real time

Researchers from MIT’s Computer Science and Artificial Intelligence invented a robot fish which can swim in the open water along with studying the real sea creatures. The robot fish is named as SoFi, which will explore marine environments. In the recent years, robotic fish have become increasingly discussed topic. They can be considered as “secret agents” of the marine world. The new CSAIL robofish, SoFi, can swim in the forward direction, turn/change direction, change speeds, move up and down, driving itself by wagging its tail side to side, just like a real fish. Creating the latest and the most advanced robotic fish in the world requires a rocket science technology and unique designs. But, when it came to controlling method for the fish, researchers decided to go with old school method. For all the movements, this robotic fish is controlled by a Super Nintendo controller.

According to a press statement, by CSAIL PhD candidate Robert Katzschmann, SoFi is the first robotic which can swim independently in three dimensions for extended periods of time. They are excited for using such system for the first time to get closer and study marine life in depth, than humans can get on their own.

Design of SoFi

SoFi is a well designed and realistic robotic fish which can go up to 50 feet deep into the open water as long as 40 minutes. It is designed in a way it can stand against currents and take high-resolution photos deep in the water. Its back is made of silicone rubber along with flexible plastic. Head is 3D-printed which equips all the electronics. The mechanism to swim is, its motor pumps water into two balloon-shaped chambers in its tail, functioning similar to a piston in an engine. Expansion of chamber makes the fish bend to any of the sides.

SoFi can explore marine world!

Just like Nemo or Dory, SoFi is here to uncover the deepest ocean mysteries. CSAIL had designed the robot which looks and moves just like a real fish. It was tested in the Rainbow Reef off the coast of Fiji, where it swam at depths of over 50 feet along with the real fish. Its look, movements and realistic soft body design allow greater control over it. As 71 percent of the surface of our planet is covered by water, CSAIL’s SoFi will be the most exciting contribution towards the world. It will help to unveil the darkest and deepest mysteries of the world. Hence, SoFi will receive more attention than other CSAIL’s advances in robotics.

The team is currently working on improved pump system for SoFi and minor changes in the body along with the tail. After that, they are planning to build more SoFis to study real fish. SoFi can be considered as the first underwater observatory stuff. It can explore and unveil the deepest and the darkest mysteries of marine life.
