Robot sea turtle helps breed fish

The U-CAT sea turtle robot will help breed fish. According to preliminary studies, it can collect more data without disturbing the calm of the fish.

Maarja Kruusmaa and his colleagues from Tallinn University of Technology in Estonia have developed a robotic sea turtle called U-CAT.

U-CAT is autonomous and can independently move up and down, forward and backward, selectively moving four independently controlled flippers. When the researchers tested it in a salmon aquarium on a Norwegian fish farm, the fish remained calm, swimming close enough to the robot and staying calm. This will allow farmers to receive detailed data on the quality of water, food and their conditions.

According to Kruusmaa, the secret to the success of U-CAT is that it is small and moves slowly. This is what allows the device to collect more data than other robots that can move in the water.

In the future, researchers will equip the turtle with several sensors and trackers that will collect more data about the fish. In addition, the design of the robot will change – it will merge with the environment around.
