It is a kind of sensor which uses infrared as the medium to complete the measurement function. Infrared is also called infrared light. It has the properties of reflection, refraction, scattering, interference, absorption, etc. during the measurement, the infrared sensor does not directly contact with the measured object, so there is no friction, and it has the advantages of high sensitivity, fast response, cheap, easy to make, safety, etc. At present, the infrared photoelectric switch is widely used. Its transmitting frequency is about 38 kHz, and its detection distance is generally short. It is usually used for the recognition of short-range obstacles. The infrared sensor used in this design is a kind of photoelectric sensor which can transmit and receive. The infrared sensor is mainly used to measure the distance between the climbing robot and the obstacles around the car body, and the forward distance of the climbing robot.<br>
