Quadruped robot fire rescue.

Detection Edition and Water Cannon Edition

40 L/s

Adjustable water cannon flow

60 m

Max spray range

> 15 km

Detection Edition range

40°

Inclines and 40 cm obstacles

Smart fire relief

Six steps from reconnaissance to evacuation.

0101

5G + mesh network navigation

Beyond-visual-line-of-sight control: remote route reconnaissance and hazard spotting, first in high-risk zones.

0202

Thermal imaging & gas detection

Life detection locates trapped people and fire sources; real-time gas analytics guide on-site safety decisions.

0303

3D radar mapping

Instant scene modelling builds command-ready maps that highlight safe routes and enable autonomous logistics.

0404

Fire suppression & hose deployment

Efficient water or retardant delivery in confined spaces such as high-rises; self-cooling mode works in extreme heat.

0505

Logistics & rescue coordination

Transports critical supplies, autonomously or with firefighters, and syncs with wider dispatch operations.

0606

Voice-guided evacuation

Scans evacuation paths for hazards and guides people out: a lifeline during emergencies.

Water Cannon Edition

Equipped modules.

B2 Water Cannon Edition modules

Foam nozzle

Built for flammable and combustible liquid fires; suppresses vaporisation and pyrolysis to stop the fire spreading.

Management platform

One view of the whole fire scene.

The Unitree Firefighting Quadruped Robot Visualization Platform streams audio, video, environment data, track paths and operating control to a command centre, over satellite, 4G/5G and MESH-AP.

Unitree firefighting robot visualization platform

Command & control centre

Unified multimedia communication with GIS and live stream.

Multi-network

Satellite, 4G/5G and MESH-AP.

Remote command support

For emergency firefighting operators.

Mobile charging station

With a forward command post.

Case studies

Proven in real fire drills.

Qingdao Fire & Rescue

Qingdao Fire & Rescue

Official deployment: two quadruped robots integrated into the emergency response unit, improving rescue efficiency in complex environments.

Commercial complex drill

A simulated grease-duct fire in an underground mall store: the robot climbed the escalator for multi-level detection and real-time command support.

Forest fire rescue drill

Robotic firefighting canines handled reconnaissance, heat-source localisation and post-fire monitoring: patrol → inspection → prevention → extinguishment.

Detection Edition

Approx. 90 kg, 25 kg payload, 3.5 m/s, IP66, 360° panoramic camera, dual-optical PTZ, gas sensor and 3D laser scanner.

Thermal & gas detection

Locates trapped people and fire sources through smoke.

Logistics & evacuation

Carries supplies and guides people out with voice prompts.
