Collision sensor: Determines the presence of obstacles ahead by detecting collisions.
Cliff sensor: The strength of the received infrared signal is used to judge the height of the drop and prevent the robot from falling. Effective detection range: 1–10cm
Speed sensor: Primarily designed to measure the wheel speed. No distance measurement function
Induction sensor: Detect the presence of functional components (such as the water tank) through magnetic field induction between the sensor and a magnet. No distance measurement function
Gyroscope (IMU): Detects the angle changes of the robot using an IMU. No distance measurement function
Radar sensor: Use radar distance measurements to judge whether there are obstacles ahead and how far away they are, and assist the robot as it plans its path. Specified range: approx. 0.16m–8m
Recharge sensor: The charging dock emits infrared signals, which the robot receives to accurately align itself with the charging dock for recharging. Effective range: approx. 4m
