Power management system and method for motor-driven four-legged robot

The invention discloses a power management system and method for a motor-driven four-legged robot. The system comprises a battery pack, a battery management board and a voltage regulator board connected in sequence; the battery pack is used for powering a motor-driven four-legged robot; the battery management board is used for detecting the power supply parameter of the battery pack and receivingthe power supply output parameter of the voltage regulator board, and managing the battery pack according to the power supply parameter and the power supply output parameter; the voltage regulator board is used for performing voltage regulation of the voltage outputted by the battery management board, monitoring the power supply output parameter, and feeding back the power supply output parameterto the battery management board. Therefore, on the basis of providing the working state monitoring function and the perfect protection mechanism, the power supply output parameter is stable, the computing load of the battery m
