The basic architecture of the sweeping robot usually includes the central processor, power/battery management unit, battery charger, wireless communication module, human-machine interface, sensor and drive module (brushed and brushless motor). With the further improvement of market and application requirements, motor drive and lithium management are also developing in the direction of high power density, miniaturization, and long continuous working time, first of all, the power device is required to be reliable and energy-efficient, and second, a new package shape to achieve a smaller volume design is also very important.
