Control method and system of seabed stratum space robot

The invention relates to a control method and system of a seabed stratum space robot, in particular to the technical field of seabed stratum space robots. Before the robot starts to move, a preset operation point is set, and in the moving process of the robot, the action of the next moment is obtained according to the preset operation point, the state of the current moment and a control model of the current moment; the states comprise attitude information, positioning information and resistance in the movement process of the seabed drilling robot and working states of driving hydraulic cylinders in the seabed drilling robot; the action is used for controlling movement of the seabed stratum space robot; the action comprises a control instruction of each driving hydraulic cylinder in the seabed drilling robot; the control model at the current moment is a model obtained by updating the control model at the previous moment based on a DDPG algorithm. According to the invention, automatic control of the seabed stra
