Fish nurseries need to be checked regularly for tightness, and the fish for disease and parasites. Still, this work is usually performed by divers. However, due to their size, clumsiness and a large number of exhaled bubbles they create for fish serious discomfort.
A group of researchers of the Tallinn University of technology led by Professor Maria of Kruusmaa has developed an alternative to the role of the inspector of the fish farm is equipped with camera is a robotic sea turtle U-CAT.
U-CAT is fully Autonomous and can move in any direction. When Kruusma and her team tested the robot on a Norwegian fish farm, the fish remained calm, being in the vicinity of U-CAT. In contrast, salmon avoided to approach there are divers and even to other managed devices.
According to Kuusmaa, the secret of the success of U-CAT among the fishes, most likely, lies in its small size and smooth movements, despite the unattractive appearance.
