Industrial-grade quadruped robot with maximum speed of 6 m/s
Integrated Nav Kit adds autonomous navigation, 3D mapping, and obstacle perception
Handles payloads exceeding 40 kg for diverse sensor and equipment configurations

The Unitree B2 Industrial-Grade Quadruped Robot Dog w/ Nav Kit, built by Unitree Robotics, is an industrial-grade legged quadruped platform engineered for autonomous deployment in challenging real-world environments. This variant of the B2 series integrates a navigation kit that adds autonomous path planning and environmental perception on top of the platform's high-performance locomotion system. The B2 maintains stable operation across slippery surfaces, uneven terrain, staircases, and obstacle-laden environments. It is designed for utility infrastructure inspection, emergency rescue operations, and large-scale industrial facility monitoring.
The navigation capability uses infrared scanning and three-dimensional mapping to generate real-time environmental models for route planning and obstacle avoidance without continuous operator input. Deployment is flexible, supporting direct teleoperation as well as fully autonomous mission modes depending on application requirements. Extended battery runtime and autonomous charging solutions together support prolonged fieldwork with reduced downtime (charging dock sold separately). The platform integrates with ROS-compatible workflows and the Unitree B2 SDK, giving researchers, system integrators, and enterprise teams the tools to build and deploy custom autonomy stacks. A high payload capacity accommodates a wide variety of inspection instruments and mission-specific sensor configurations.

Capabilities
Autonomous Navigation
The B2 Nav Kit integrates infrared 3D mapping and environmental perception to plan and execute autonomous missions without human input.
ROS & SDK Ecosystem
Full ROS-based development workflows and comprehensive SDK allow researchers and engineers to build custom autonomy stacks.
All-Terrain Adaptability
Designed to operate reliably across slippery, uneven, and obstacle-laden surfaces. Its exceptional obstacle-crossing capability allows deployment in disaster zones and industrial facilities.
Payload & Accessory Integration
With a sustained load capacity exceeding 40 kg, the B2 supports a wide range of sensor payloads and inspection instruments.
Use Cases & Application Scenarios
Power Infrastructure Inspection
The B2 Nav Kit conducts autonomous inspection rounds across substations and transmission infrastructure, following pre-planned routes without continuous operator input. Its all-terrain legged mobility and onboard navigation stack allow it to reliably cover extended facility areas.
Emergency & Rescue Operations
In emergency response scenarios, the B2 Nav Kit traverses rubble fields and unstable surfaces ahead of personnel. Its navigation stack enables semi-autonomous scouting of hazardous areas, reducing the need for direct operator presence near the affected zone.
Industrial Site Inspection
Manufacturing plants and industrial facilities deploy the B2 Nav Kit for repeatable autonomous inspection rounds — detecting anomalies and maintaining consistent data collection schedules without continuous operator supervision. Extended endurance supports multi-hour site coverage on a single charge.
Security & Perimeter Patrol
The B2 Nav Kit executes programmed security patrol routes across industrial sites and facility perimeters without continuous operator involvement. Its navigation stack enables scheduled patrol missions, autonomously covering stairwells, uneven grounds, and outdoor access points.

Navigation Kit
Not available on the standard B2. Exclusive to this configuration.
The Navigation Kit is a hardware and software add-on that turns the B2 into a fully autonomous platform. Rather than simply adding a sensor, the kit integrates a dedicated LiDAR, its own navigation compute unit, and an onboard autonomy software stack that handles localization, mapping, and route execution without requiring constant operator input.
The result is a robot capable of executing pre-defined or dynamically planned missions across complex terrain, building a real-time 3D map of its surroundings, and detecting and routing around obstacles, all without human guidance.
