In a method for controlling a robot, movement of the robot is controlled according to a first controller. Motion state data and control data of the robot are obtained while the movement of the robot is controlled according to the first controller. A linear equilibrium parameter matrix of the first controller is updated according to a policy iteration algorithm that uses the obtained motion state data and the control data. A second controller of the robot is built based on the updated linear equilibrium parameter matrix.
