UNDERWATER ROBOT FOR CLEANING HULL SURFACE USING WATER DEPTH INFORMATION

摘要

The present invention relates to a robot to clean a hull (10) underwater, comprising: a main body (20) having a plurality of brushes (25); an actuator (30) to vertically or horizontally move the main body (20); and a detection unit (40) to generate a signal corresponding to the changes in positions of the main body (20). Therefore, the present invention enables the robot to smoothly clean the hull by three-dimensionally correcting the position based on a pressure sensor, and to carry out perfect cleaning by grasping the moving distance using information on the water level.
