1.	Definition and Introduction
                            A robot vacuum cleaner is a small household cleaning device equipped with intelligent technology that can autonomously perform floor cleaning tasks. It typically features various sensors, a vacuum system, and smart navigation functions, allowing it to efficiently clean floors without the need for manual intervention.

                            •	Main Body: Designed in a circular or D shape for easy maneuverability in narrow spaces.
•	Sensors: Including collision sensors, infrared sensors, and laser radar (LiDAR) for positioning and obstacle avoidance.
•	Vacuum System: Consisting of an internal vacuum motor and dustbin to collect dust, debris, and hair.
•	Battery and Charging Dock: Equipped with a rechargeable battery and typically featuring automatic recharging functionality.
•	Control System: Supporting smartphone app control, voice assistant operation, and even learning functionality to optimize cleaning paths based on user needs.

                            •	Environmental Perception: Using sensors and navigation technology to map the home environment and determine the cleaning area.
•	Path Planning: Intelligent algorithms select the optimal cleaning path to ensure no area is missed.
•	Cleaning Execution: Brushes and suction systems work together to collect dust into the internal dustbin.
•	Obstacle Avoidance and Return: Maneuvering around furniture or other obstacles, the robot vacuum cleaner automatically returns to the charging dock after completing its task.
