CETUS

Long description

Cetus is an autonomous fishing robot revolutionising bottom trawling. Instead of destructively plowing through the seabed, the robot lures the fish into the net. With sensors and flaps the catch gets sorted during the fishing process, releasing bycatch instantly and in their natural habitat. The robot can also detect plastic waste and collect it either exclusively or in a separate tank. The sensors monitor and analyse the seabed, the water and the biomass over long periods of time. This data provides the basis for sustainable and responsible fishing.

The robot consists of three different units and seven in total. The two Tractors on the front pull the net and the Collector. The water stream of the tractors is partially diverted downwards to lure the catch out of the seabed and swirl plastic waste from the seafloor. The startled fish or plastic waste is then collected by the net which is held as close as possible to the seabed by the four Pilots. The net guides the catch to the collector, where it gets sorted and stored. The bycatch leaves the robot at the same place where it was caught. When the storage is full, the robot stores the net, the tractors and the pilots inside the bycatch channel. The Collector returns to the mother ship, where the catch is dropped, the batteries are recharged and the collected data is transferred.
