Unitree B2 Fire Rescue Quadruped Robot Dog (B2-XF2-A)

Getting water to a fire is rarely the hard part; getting it to the right place is. Stairwells, blocked corridors and heat that turns people back all stand between the hose and the flames. The Unitree B2 Fire Rescue Quadruped Robot Dog (B2-XF2-A) is a four-legged machine built to walk into that gap, so crews can see, aim and act before anyone has to step into danger.

Background

Unitree Robotics and the B2 lineage

Unitree Robotics is known for legged robots, and the B2 is its proven industrial-grade quadruped. The fire rescue family is based on that B2 platform and has been specifically designed for hazardous environments. Rather than starting from a blank sheet, the fire versions take a walking platform that already works and adapt it to heat, water, dust and smoke.

The family is organized by designation. Models marked XF2 or F2D include the Laser SLAM kit for autonomous navigation, while models marked XF1 or F2 (without the D) are delivered without SLAM navigation. The B2-XF2-A belongs to the XF2 group, so it comes with the navigation kit. Buyers who want to compare the wider platform can browse the Unitree B2 category.

Positioning and key technology

The fire rescue robot dog is deeply integrated into fire rescue industry applications and supports modular functions and replacements. In practice, this means the robot is a carrier: the body walks, and the task equipment can change with the mission. The family includes a water cannon, an air blower and a drencher system.

The body uses a composite metal material that is wear-resistant, has high mechanical strength, and is dust-proof and waterproof. The joint performance of the inspection robot dog has increased by 170%, which supports the stability and balance needed when climbing fire stairs. Quick battery replacement while maintaining water-tightness is of great significance for rescue efficiency and safety, and the robot is designed around it.

What makes the B2-XF2-A different from the other fire rescue versions?

The deciding feature is navigation. Models designated XF2 or F2D include the Laser SLAM kit for autonomous navigation, and models designated XF1 or F2 are delivered without it. The B2-XF2-A carries the XF2 designation, so it is in the group that ships with the kit. For a fire service that wants the robot to move through a known building with less manual steering, that matters more than almost any other line on the list.

Lettered versions of the same family are also listed on this store, such as the B2-XF2-B and the B2-XF2-C.

How does it work in heat, water and rough ground?

Fire scenes punish ordinary electronics. The composite metal body is wear-resistant, dust-proof and waterproof, and the drencher system lets the robot continue to operate in high-temperature environments without being affected by heat, which improves fire-extinguishing efficiency. The base B2 robot is rated IP67 and works from -20°C to 55°C.

On the move, the maximum height for ascending and descending steps facing front is 40 cm. When climbing fire stairs, the robot has excellent stability and balance. The base B2 runs at 6 m/s, which means it can reach a scene quickly before it starts to work.

For the fire task itself, the water cannon has a body-compensated angle, a pitching range of 5 - 85°, a water flow rate of 40L/s and a firing range of 60m, and it can use water or foam. The air blower robot dog extinguishes forest fires through high-speed airflow. These are task modules that can be swapped to suit the mission.

Who is the B2-XF2-A for?

Municipal and regional fire brigades are the obvious buyers. They can send the robot ahead of a crew to look at a corridor, a stairwell or a smoking room, and then use the water cannon or the blower from a distance. Industrial sites with their own fire teams, such as fuel storage, power generation and large warehouses, have the same need on a private scale.

Emergency planners and civil protection agencies in the Caribbean may also find the robot useful where buildings are tightly packed and access is poor. Training institutions and research groups can use it to study how legged robots behave in fire scenarios. Buyers who do not need autonomous navigation can look at the XF1 and F2 designations, which are delivered without SLAM; those who want to compare lettered siblings can start with the B2-XF2-D. For buyers who need a wheeled industrial platform rather than a fire configuration, the B2-W Industry Grade Quadruped Robot Dog with Wheels is a different product to consider.

What is the B2-XF2-A used for?

1. Fire scouting: the robot walks ahead of the crew and shows what is inside a building before anyone enters.
2. Thermal inspection: the dual-optic PTZ camera pairs a 4MP visible light view with 33× optical zoom and a 640×512 thermal imager.
3. Water and foam delivery: the water cannon reaches 60m at a flow rate of 40L/s and can use water or foam.
4. Forest fire control: the air blower version puts out forest fires through high-speed airflow.
5. Stair and debris access: the robot climbs and descends steps up to 40 cm high facing front, with stability on fire stairs.
6. Site mapping: the 3D laser scanning system with 16 beams and 1cm accuracy builds a picture of the scene, and the Laser SLAM kit supports autonomous navigation.

Frequently Asked Questions

Does the B2-XF2-A include autonomous navigation?

Yes. Models designated XF2 or F2D include the Laser SLAM kit for autonomous navigation. Models designated XF1 or F2 without the D are delivered without it.

How high a step can it climb?

The maximum height for ascending and descending steps, facing front, is 40 cm. The robot has excellent stability and balance when climbing fire stairs.

What can the water cannon do?

The water cannon has a body-compensated angle and a pitching range of 5 - 85°. It delivers a water flow rate of 40L/s with water or foam, and its firing range is 60m.

Is the robot protected against dust and water?

The body is made of composite metal that is dust-proof and waterproof. The base B2 robot has an IP67 protection rating.

Can the battery be changed quickly?

Where can I buy the B2-XF2-A and what does it cost?

You can request it through this page. The cost depends on the configuration and payloads, so we give it in a quotation instead of a list price.

Summary

The hard part of a fire is reaching it, and the B2-XF2-A is made for that problem. It brings a B2-based walking body in composite metal, a Laser SLAM kit for navigation, 40 cm step climbing, and a family of water cannon, air blower and drencher functions together on one platform. It lets the crew see and act first, and keeps people back from the heat. For a quotation tailored to your brigade or site, this page is the starting point.
