In recent years, coral reefs decrease in Okinawa. One of the reasons is outbreak crown of thorns starfish. Hence, we have been researching to use underwater robot for exterminate crown of thorns starfish. The underwater robot cannot use radio communication in underwater. So, the robot cannot use GPS. The authors propose the floating robot to measure position of the underwater robot. The floating robot has a network camera and a GPS and an attitude sensor. The floating robot measures position of underwater robot by using these sensors. The authors illustrate design of floating robot in this paper.
