4. Detection and search and rescue system: The fire-fighting robot is equipped with a remote intelligent alarm system, including high-temperature sensing, smoke sensing, gas sensing, infrared detection, sound pickup system and remote loudspeaker system. The robot can sense dangerous situations such as high temperature, gas and smoke in the surrounding environment, and can also collect sounds around through the sound pickup system and conduct search and rescue through the loudspeaker system. And the collected signals can be remotely transmitted to the operators. 

5. Intelligent cooling system: After the robot enters the fire scene, it can control its own temperature through a temperature sensing device. When the temperature exceeds the set value, the robot automatically activates the intelligent cooling system to start cooling. When the temperature drops below the set value, the intelligent cooling system stops working, maintaining its own temperature within a relatively safe range. Avoid the harm that high-temperature environments may cause to the robot itself. 

6. Remote control system: The fire-fighting robot can be remotely controlled through two wireless methods. The first control method is local area network remote control within 1 kilometer. Within 1 kilometer, the industrial-grade wireless base station configured by itself can meet the requirements. The second method is 3G/4G network remote control. By connecting to the local area network through the 3G/4G module built into the robot, remote control without distance restrictions can be achieved. 

7. Solar self-charging system: The intelligent crawler-type fire-fighting robot is equipped with a solar self-charging system. Under normal sunlight conditions on a daily basis, it can charge itself to extend the driving range.
