Full ROS2 driver support and Unitree B2 SDK with over-the-air software update capability
Unitree B2-W Wheeled Industrial-Grade Quadruped Robot Dog w/ Nav Kit is an industrial-grade wheeled quadruped robot from Unitree Robotics, engineered for continuous deployment across variable terrain in real-world field environments. It combines legged walking with wheeled rolling in a single frame, allowing it to transition between locomotion modes based on the ground conditions encountered. As the navigation kit variant of the B2-W line, this configuration ships with an integrated nav kit that extends the platform into autonomous path planning and obstacle avoidance, enabling unsupervised mission execution beyond what teleoperation alone can support. The B2-W Nav Kit addresses industrial inspection, emergency response, field research, and other deployments where terrain unpredictability and operational independence are simultaneous requirements.
Environmental awareness is built on infrared-based three-dimensional mapping combined with a multi-sensor perceptual and motor control approach, giving the platform a real-time understanding of its surroundings for both navigation planning and dynamic balance correction. Operators can deploy fully autonomous missions through the navigation kit or retain direct teleoperation for supervised tasks, depending on the operational context. Multi-joint synergistic stabilization responds to discrete terrain transitions rapidly, maintaining platform stability even when the robot switches between legged and wheeled modes mid-route. Developers access the full ecosystem through ROS2 drivers and the Unitree B2 SDK, with continuous over-the-air updates keeping software current without manual intervention. The platform is designed for research institutions, industrial operators, and field robotics teams that require a robust, extensible autonomous quadruped robot with a demonstrated commercial deployment record.

Capabilities
Four core platform capabilities that define the B2-W Nav Kit's value in autonomous field deployment.
Autonomous Navigation
The integrated Nav Kit equips the B2-W with onboard path planning and obstacle avoidance for unsupervised mission execution.
ROS2 & SDK Integration
Full ROS2 driver support and the Unitree B2 SDK allow developers to build, extend, and simulate custom applications.
Sensor Fusion & 3D Mapping
Infrared-based 3D mapping combined with multi-sensor fusion gives the B2-W a detailed, real-time understanding of its surroundings.
IP67 Field Durability
An IP67 ingress protection rating ensures the B2-W Nav Kit can operate continuously in dusty, wet, and harsh outdoor conditions.
Use Cases & Application Scenarios
Real-world deployments where the B2-W Nav Kit's autonomous mobility and all-terrain capability create operational value.
Power Infrastructure Inspection
The B2-W Nav Kit autonomously navigates power infrastructure facilities, blending wheeled speed on flat service roads with legged walking for complex terrain transitions. Its integrated navigation stack enables repeatable, scheduled inspection runs across large industrial sites without operator intervention.
Emergency & Rescue Operations
In emergency response scenarios, the B2-W Nav Kit provides a rapidly deployable scouting platform — rolling at speed toward the incident then switching to legged walking across rubble or unstable terrain. Its navigation stack enables semi-autonomous operation in environments that limit direct operator proximity.
Industrial Site Inspection
Industrial facilities deploy the B2-W Nav Kit for autonomous inspection cycles spanning both smooth interior floors and rough outdoor areas. The robot transitions between wheeled and legged modes as terrain demands, executing pre-defined routes and reporting data without a dedicated operator.
Security & Perimeter Patrol
The B2-W Nav Kit runs autonomous security patrol schedules across mixed environments — rolling efficiently along perimeter roads and transitioning to legged walking for stairs and uneven access areas. Pre-programmed routes and real-time obstacle avoidance enable unattended patrol coverage across large facility footprints.

Included With This Configuration
Navigation Kit
Not included on the standard B2-W. Available only with this configuration.
The Navigation Kit is a hardware and software add-on that turns the B2-W 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.
