A method for using the underwater robot waste recycling and classification device as claimed in claim 8, characterized in that: The following steps are involved: Step 1, when in use, first start the second motor (115), the output end of the second motor (115) drives the rotating blade (116) to rotate, pushing the first housing (101) to move; Step 2, when turning is required, the first motor (104) is started again, so that the first motor (104) rotates the semicircular gear bar (106) movably connected on the outer side, and the semicircular gear bar (106) drives the first rotating piece (110) at the upper end to move when moving, so that the first housing (101) can change the track to turn; Step 3, when garbage collection is required, the third motor (312) on both sides of the cross bar (309) is started. When the third motor (312) rotates, it drives the cross bar (309) to retract inward, so that the second slider (304) drives the third slider (305) to retract inward. When the third slider (305) retracts inward, the flat sheet (306) connected with bolts at the upper end is pressed and bent, so that the net bag (308) can be opened to recycle garbage.
