Intelligent floor sweeping robot is a new type of floor and carpet cleaning tool designed for modern home environments. It uses rechargeable batteries as a power source and integrates cleaning and vacuuming functions. The basic architecture of a robotic vacuum cleaner typically includes a central processing unit, power/battery management unit, battery charger, wireless communication module, human-machine interface, sensors, and drive modules (brushed and brushless motors). With the further improvement of market and application requirements, motor drives and lithium battery management are also developing towards high power density, compact size, and long continuous working time. Firstly, reliable and energy-efficient power devices are required. Secondly, a new packaging shape is also very important to achieve smaller designs.
