Have you ever found yourself watching a devastating fire on TV and thinking about the risks firefighters face? Unitree, a company specializing in robotics (you know that robot that does kung fu? I talked about it here), has developed a solution that could keep humans away from flames: a four-legged robot firefighter. Yes, sir: a mechanical quadruped that is already operational and is entering service with firefighting teams.
By modifying his model B2 (a kind of Spot, the robot dog from Boston Dynamics), the Chinese company has created a robotic system capable of carrying a powerful water cannon directly into the heart of the inferno. The firefighting robot does more than just put out flames, it can also perform reconnaissance, map environments and monitor dangerous areas.
A firefighter robot with interchangeable modules
This robot dog is not just a technological toy, but a real mechanical firefighter. It can be equipped with various specialized modules: robotic arms, LiDAR sensors and communication equipment. Its most impressive feature? A water cannon that fires up to 60 meters away with a range of 40 liters per second. The hose attaches to the back, while the nozzle can be tilted up to 85 degrees to accommodate different extinguishing needs. And it's not limited to water: it can also use foam, expanding its operational capabilities.
Designed to withstand hell
Flames don’t scare this mechanical firefighter. It even has a built-in sprinkler system—not to put out outside fires, but to keep the robot itself cool when everything around it is burning. Waterproof and dustproof, its body is made of metal composite materials that contribute to its ability to operate in extreme environments.
The robot is a firefighter already in service
Unitree has enhanced joint performance compared to the standard B2 model of 170%, giving the firefighting robot superior climbing ability to tackle obstacles up to 40 centimeters high and stairs with a 45-degree incline. Additionally, it features a hot-swappable battery system for extended use in the field without compromising waterproofing.
This is not a future project or a prototype in the testing phase. The firefighting robot has already passed numerous tests and exercises to demonstrate its capabilities, and two units have recently joined the Qingdao Fire and Rescue Support Team in an official capacity. The units are now available for sale, although the company has not yet announced prices. After drones, even “ground” devices can help the real heroes who protect us from fire: we just have to see them in action.
