Patrol robots have the capabilities of autonomous perception, autonomous walking, and autonomous protection to help humans complete basic, repetitive, and dangerous tasks. It is a multi-functional integrated intelligent equipment. Some dangerous areas or complex areas have high labor costs and high risk factors. During the special epidemic, the crowd is evacuated and manual temperature measurement is faced with close contact. This robot can realize long-range cruise, temperature measurement, crowd evacuation, and realize 0-contact patrol security to reduce security labor costs to the greatest extent. He is a small helper during the fight against the epidemic. All kinds of sensing modules have complete functions and can realize the detection and analysis of people and things under various application scenarios.
