Problem 2: The second ocean pollution now causes many deaths of marine animals and destroys the ecological environment, so marine garbages should be cleaned up. So there is an urgent need for a machine to replace human beings to solve the above problems. Aim: Cleaning up ocean plastic waste & helping fishermen salvage procedures more efficiently.
