As explained above, if the work boat anchor changing method of the present invention is adopted, the unmanned anchor changing floating robot can be radio-controlled to replace the work boat's anchor, and can be used at night or in waves. Even when the anchor-moving work environment is bad, such as during the winter, the anchor-moving work can be carried out safely, and the work efficiency is also improved.
