A firefighting robot is a high-tech device designed for dangerous situations, such as chemical fires. These robots are capable of adapting to different terrains, such as stairs, slopes and rough ground, and they are often used when humans cannot go deep into locations that are filled with thick smoke and high temperatures.
Firefighters operate these robotic devices from a safe distance, guiding them via remote control to the core area of the fire scene. The robots are equipped with a range of sensors to monitor temperatures, toxic gas concentrations and they provide fire source location data in real-time at the scene.
HKP Motors are used in firefighting robots to perform a range of tasks, such as powering the water pumps, turning the pumps on and off, controlling the tracks that move the robot, and also controlling the angle and movement of the nozzle that delivers the water or fire suppressant foam.
Key Challenges:
- Strong overload capacity in short time
- Good stability and consistency
- Waterproof and corrosion resistant
- Vibration resistance
- Must be able to tolerate 80°C environments
