A control system for underwater robot is composed of supporting base ship, rescue vessel, repeater, underwater recovery system and underwater robot (autonomous diving instrument). The supporting base ship is connected via steel cable and electric cable with repeater, which is then connected to retraction apparatus. The underwater robot is controlled and recovered by sonar system and retraction apparatus. It has compact structure, high reliability and can recover cableless underwater robot at 30-50 m depth under water surface in class -4 sea condition.
