  • Stable autonomous charging capability with OTA firmware updates (charging dock sold separately)

The Unitree B2-W Wheeled Industrial-Grade Quadruped Robot Dog is an industrial-grade autonomous mobile robot from Unitree Robotics that integrates legged and wheeled drive into a single platform capable of full-scene adaptation. As the wheeled variant within the B2 series, it introduces an innovative structural configuration that allows switching between legged walking and wheeled rolling to match terrain conditions. Proprietary joints deliver highly dynamic motion through rapid, synergistic multi-joint responses, maintaining stability across discrete and uneven surfaces. Built for deployment in demanding field environments, the B2-W addresses use cases ranging from power infrastructure inspection to emergency response and outdoor autonomous navigation.

The robot perceives its environment through onboard depth cameras that provide real-time spatial awareness for obstacle detection and avoidance during teleoperated missions. Perceptual and motor control systems work in combination to keep the platform balanced across challenging surfaces encountered in industrial and outdoor scenarios. Developers and systems integrators can interface with the B2-W through the official Unitree SDK and ROS2-compatible drivers, enabling custom autonomy layers to be built directly on the platform. Third-party payload mounting support and an open accessory ecosystem make the B2-W suitable for research institutions, industrial operators, and commercial organizations requiring a versatile all-terrain robotic platform.

Model Features
An overview of the B2-W platform across mobility, environmental sensing, and developer integration.
Capabilities

The B2-W is built around four core capabilities that enable autonomous operation, open development, and versatile deployment across industrial and research environments.

Obstacle Detection & Avoidance

The B2-W uses onboard depth cameras to detect obstacles and assess terrain in real time, automatically avoiding hazards during teleoperated missions across complex environments.

ROS2 & SDK Integration

Full ROS2 driver support and an official Unitree SDK enable developers to build and deploy custom autonomy stacks on the B2-W platform.

OTA Software Updates

Continuous over-the-air firmware and software updates keep the B2-W current with the latest motion control algorithms and feature releases.

Hybrid Locomotion Modes

The B2-W transitions seamlessly between legged walking and wheeled rolling, selecting the optimal mode for the terrain at hand.

Use Cases & Application Scenarios
The B2-W is designed for field-ready deployment across industrial, emergency, and all-terrain environments where hybrid mobility and environmental resilience are required.
Power Infrastructure Inspection
The B2-W covers large utility and power infrastructure sites efficiently — rolling at speed across flat service roads then switching to legged walking for uneven or obstacle-laden areas. Its IP67-rated enclosure sustains continuous operation in demanding outdoor industrial environments.
Emergency & Rescue Operations
In emergency and rescue scenarios, the B2-W rapidly covers ground using its wheeled drive then transitions to legged walking to negotiate rubble and unstable surfaces that restrict conventional platforms. It carries sensor or communication payloads into affected areas to support situational assessment.
Industrial Site Inspection
Manufacturing plants and logistics facilities benefit from the B2-W's hybrid mobility — wheeled rolling across flat warehouse floors and legged walking through loading docks and uneven outdoor yards. Its IP67 rating sustains reliable operation in environments with dust, moisture, and varied surface conditions.
Security & Perimeter Patrol
The B2-W's hybrid locomotion and sustained endurance make it practical for security patrol across mixed environments — rolling efficiently along outdoor perimeter roads and switching to legged walking for stairwells and uneven indoor areas while carrying camera or sensor payloads.
