The core structure of a sweeping robot mainly includes the host (including processor, sensor and drive system), cleaning module (side brush, roller brush, suction port, dust box, etc.), power supply and auxiliary components (such as water tank, rag, etc.). Different brands may have differences in design details and additional functions.
Host system
Processor and control system: As the "brain" of the robot, it is responsible for path planning, sensor data processing and task execution.
Sensor system:
Distance sensor (obstacle avoidance), wall sensor (edge cleaning), drop sensor (anti-drop), etc. to achieve environmental perception.
Gyroscope is used to keep the motion trajectory stable.
Drive structure:
Usually a two-wheel differential drive (independent motor control) is used with universal wheels to achieve flexible steering.
Some high-end models are equipped with telescopic arms or lifting mechanical arms to enhance the cleaning ability of low spaces.
