Power supply dynamic management method and system of quadruped robot

The invention relates to a power supply dynamic management method and system for a quadruped robot, and the method comprises the steps: obtaining the working state of each motion module in the quadruped robot, reducing the motor input voltage of the motion module if the motion module stops working, and maintaining the motor input voltage above the rated voltage of the motor; judging whether the image is in a static state or not according to the image acquired by the quadruped robot, if so, reducing the video frame rate of the image acquired by the quadruped robot, and otherwise, keeping a normal state for video acquisition; the electric quantity of the quadruped robot and the time for receiving the operation instruction are obtained, and if the electric quantity of the quadruped robot is lower than a preset low electric quantity threshold value and the time for not receiving the operation instruction is longer than preset silence time, a CPU of the quadruped robot is controlled to run under the limitation of
