In view of the current problems of inconvenient control and low intelligence of shot blasting device, a shot blasting robot system for ship deck is designed. The structure composition, control system, software design, and laser guidance planning workflow of the system are discussed, and the test is conducted on the deck of an actual ship. The test results show that the system can control the operating links of shot blasting, dust removal, and moving, and is of certain operating function of self-guiding shot blasting.
