Underwater robot gravity center auxiliary adjusting system and control method

The invention relates to an underwater robot gravity center auxiliary adjusting system and a control method. A posture detection system is used for detecting a posture of an underwater robot body; anunderwater robot motion information input module is used for detecting motion control information of the underwater robot body and motion control information of an underwater mechanical arm which is carried on the underwater robot body; an adjusting motion controller derives gravity center change tendency and size of an underwater mechanical arm according to longitudinal inclination posture information of the underwater robot, motion control information of the underwater robot and motion control information of the underwater mechanical arm and controls a screw-slide block mechanism and adjuststhe gravity center of the underwater robot; and the screw-slide block mechanism is an executing mechanism of the gravity center auxiliary adjusting system. According to the underwater robot gravity center auxiliary adjusting
