Robotic technology has finally moved beyond science fiction and entered real-world emergency operations. Unitree Robotics, one of the global leaders in quadruped robot development, introduces the B2 Fire: a robot designed to protect human lives in high-risk environments. Equipped with artificial intelligence, cutting-edge sensors, and ultra-resistant structure, the B2 Fire represents the technological revolution applied to public safety.
What is the B2 Fire?
The B2 Fire is a high-performance quadruped robot designed to operate in extremely hazardous environments, such as urban fires, forest fires, industrial accidents, landslides, and earthquakes. It combines advanced mobility with intelligent environmental sensors and real-time communication features.
More than merely replacing humans in dangerous scenarios, the B2 Fire enhances response capability, reduces reaction time, and maximizes the success of rescue and firefighting operations.
This innovation meets a growing global demand: protecting rescue heroes and maximizing mission efficiency.

Embedded Technologies
360° Panoramic Vision System
Equipped with HD cameras, the B2 Fire streams real-time images even under bright lights, heavy smoke, or low-visibility conditions.
Bi-Spectrum PTZ Camera
Uses thermal technology to detect heat sources and locate victims through thick smoke or debris.
Advanced Gas Detection System
Monitors and detects Oxygen levels, Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), and flammable gases, issuing real-time alerts.
5G/MESH Network
Ensures stable and reliable communication even in challenging environments like tunnels, collapsed buildings, or remote areas.
High-Definition Remote Control
With a sunlight-readable screen, operators can monitor critical data and images from the robot in real-time.
B2 Fire Applications
The B2 Fire can be implemented in various scenarios, including:
- Urban firefighting in high-rise buildings
- Industrial site inspections after chemical spills
- Disaster area exploration (earthquakes, floods, landslides)
- Mountain rescue missions
- Forest fire containment and suppression operations
Strategic Benefits
Deploying the B2 Fire brings clear benefits:
- Reduces risk of injury or death among firefighters and rescuers
- Accelerates critical data collection on the field
- Increases operational efficiency and safety
- Enables faster and more accurate interventions
- Prevents further structural damages during rescues
About Unitree Robotics

B2 Fire in Action: Real Operation and Risk Monitoring
To demonstrate its real-world capabilities, Unitree has shared video footage and images showcasing the B2 Fire performing in simulated emergency scenarios.
Safe Remote Control with 5G+MESH
The firefighter remains outside the danger zone, using a portable control device to operate the B2 Fire remotely via the robust 5G+MESH connection.
Advanced Air Quality Monitoring
As the B2 Fire progresses through the hazardous environment, it continuously analyzes air quality, detecting dangerous concentrations of toxic gases such as CO and H₂S and monitoring oxygen levels.
Entering the Danger Zone
The B2 Fire autonomously moves into a container partially engulfed by flames. Its protective features and illumination system allow for detailed internal reconnaissance without endangering human lives.
Victim Detection Using Thermal Imaging
Inside the structure, the B2 Fire employs thermal imaging technology to locate hidden victims, even in zero-visibility environments, by detecting their body heat signatures.
This operational sequence shows how the B2 Fire protects rescuers, accelerates victim detection, and provides critical situational data for effective decision-making.
The B2 Fire by Unitree is not just another technological innovation it redefines the role of robotics in life-saving operations.
Equipped to tackle the most challenging scenarios, it transforms the way we handle fires, disasters, and extreme-risk situations.
With B2 Fire, the future of rescue and emergency operations is already here, walking confidently on four legs — ready to save lives.
