Modular Firefighting Robot Dog Strides Into Hazardous Areas

Unitree has unveiled a customized version of its B2 quadruped designed for firefighting. Equipped to carry specialized modules, the robotic dog features a high-flow water cannon and is built to function in harsh, high-risk environments.

While quadruped robots are often used for tasks like inspection, mapping, and surveillance, they can also enter hazardous areas to keep humans out of harm’s way. That’s the role of Unitree’s fire rescue robots, which can be fitted with surveillance modules to stream live video to firefighters at a distance, helping them evaluate conditions before deploying personnel.

Modular Enhancements for Advanced Firefighting Capabilities

Additional modules that can be mounted on its back include a robotic arm, LiDAR sensors, communication gear, and a powerful water cannon capable of reaching up to 60 meters (nearly 200 feet) with a high flow rate of 40 liters per second. The hose connects at the rear, while the nozzle can tilt up to 85 degrees to adapt to different firefighting scenarios. The system supports both water and foam, and the quadruped can automatically detach the hose and continue with other tasks seamlessly.

Thermal Protection and Rugged Design for Extreme Environments

This module also features a sprinkler system—not for firefighting directly, but to keep the robot cool in high-temperature environments. The quadruped is both dust- and waterproof, and its body, made from composite metal materials, is built to withstand extreme conditions.

Another notable add-on is an air-blower unit, designed to help control forest fires by safely breaking the link between flames and combustible materials.

Enhanced Mobility and Endurance for Challenging Terrain

Unitree has enhanced the robot’s joint performance by 170% compared to the standard B2 model, giving it the strength to climb over obstacles up to 40 cm (15 inches) high and ascend stairs with a 45-degree incline. The fire rescue robot also features a hot-swappable battery system that allows for extended operation in the field without compromising its waterproof design.

The robodog has already undergone several drills and demonstrations to showcase its firefighting capabilities, and two units have officially joined the Qingdao Firefighting and Rescue Support Team. While the units are now available for purchase, pricing details have not been disclosed.
