The first is to record and scan the overall size of the room. Through the familiarity of the environment, the microcomputer of the sweeping robot will form a fixed map of the room inside, and then make the corresponding work plan according to the current position.

The second is the identification of ground waste. It detects litter on the floor by infrared sensing. The second aspect of the intelligent sweeping robot is mainly shown in the development of cleaning methods: for the sweeping robot, there may be a lot of built-in cleaning methods, such as linear, side cleaning, spiral, cross cleaning and key cleaning. Generally speaking, the microcomputers will be based on the sense of garbage and the amount of garbage to determine the need for cleaning. Of course, robots are called robots, because it has an important function is human-computer interaction, but this function is not yet mature, so it is rarely used in robots. However, this function will be the key to whether a sweeping robot can be called a robot.

Features of the 30th sweeping robot :1. The rotating brush with 5000 revolutions per minute can clean dirt from four directions at the same time; 2. Use nickel-metal hydride (Ni-MH) battery or lithium (Li) battery as power supply; 3. The sink box can be easily removed and cleaned easily and quickly; 4. Some new sweeper is equipped with UV sterilizing lamp, which can kill bacteria while sweeping the floor.
