Underwater robot auxiliary operation system and method

The invention provides an underwater robot auxiliary operation system and method, and relates to the technical field of underwater operation. In the system, an underwater robot and an unmanned aerial vehicle are both in wired connection with a water surface buoy, a control module is in communication connection with the unmanned aerial vehicle, and the unmanned aerial vehicle measures according to a first control instruction sent by the control module, sends overwater measurement data and first position data to the control module and sends a second control instruction to the water surface buoy; the water surface buoy sends a third control instruction to the underwater robot according to the second control instruction, the underwater robot executes underwater measurement of the to-be-measured target according to the third control instruction, and underwater measurement data and second position data are sent to the control module through the water surface buoy and the unmanned aerial vehicle; the control module
