Aiming at the floating solid waste in small urban waters, a water surface garbage cleaning robot is designed. Through the garbage collection device, the pulling recovery device and the driving mechanism of the cleaning ship, the remote control of the salvage and cleaning of water surface garbage is realized by means of human-computer interaction technology, so as to protect the overall water environment. The application results show that the robot has the advantages of high cost performance, convenient operation, reliable operation and small size, which solves many disadvantages of traditional garbage collection.
