Through a lot of reports, we already know that there is a lot of garbage floating on the sea, but in fact, there is more garbage on the bed in Shanghai. The seaclear project, funded by the European Union, aims to use autonomous robots to collect most of the waste. The project consists of four robotic vehicles, including an aerial UAV, two ROVs and an unmanned surface ship as a mother ship. The latter will power the two ROVs via umbilical cables and process the data transmitted by them using the onboard computer. The system will be mainly deployed in coastal areas, as most of the waste is transported from rivers into the ocean. < / P > < p > first of all, the UAV and one of the ROVs will be used to detect garbage on the sea surface and in the water body respectively – if there is garbage in both areas, there is likely to be a lot of garbage on the seabed at that location. Next, a second ROV will enter and travel along the seabed, collecting waste using custom designed grabs and suction devices. The waste will be transported back to the surface ship and discarded in a central bin. < / P > < p > this spring, a prototype version of seaclear was tested at depths of 20 to 30 meters (66 to 98 feet) in the port of Hamburg and off Dubrovnik, Croatia. The reason for choosing these sites is that there is a big difference between the two places. Hamburg Port is busy and highly industrialized, and the water quality is quite silted up, while the Croatian coast is much more calm and clear, mainly for tourism. Global Tech
