The Unitree B2 series is developed for industrial environments where a standard mobile robot simply cannot go far enough. High payload capacity, powerful joint drives, dynamic stability control, and a robust IP67 construction make the B2 suitable for long-term deployment in complex and unpredictable terrains.
The B2 moves entirely on legs, excelling on stairs, grates, loose ground, slopes, and other locations where conventional mobile robots are limited. The platform can be equipped with LiDAR, thermal cameras, gas detection, industrial cameras, and other sensor or manipulator payloads.
The B2-W combines the same industrial base with powered wheels on its legs. On flat and semi-rough routes, it moves quickly and energy-efficiently, while the active leg kinematics remain available to overcome height differences, obstacles, and stairs. Thus, the B2-W combines the efficiency of a wheeled robot with the all-terrain capability of a quadruped.
Both platforms are designed for secondary development and can be integrated with proprietary software, sensors, and industrial systems. This makes the B2 and B2-W not just mobile robots, but configurable platforms for autonomous inspection, data collection, and industrial automation.

Inspection platform
One dashboard for routes, telemetry and measurement results
Autonomous inspection rounds deliver live RGB and thermal imagery, battery and system status, micro-weather data and automatic alerts per measurement point: including history and reporting.
Field footage
Built for terrain where others stop
The B2 and B2-W carry heavy sensor and tooling payloads across rough terrain without losing stability.
Strength and control on every step
Sustained pulling shows the torque and grip this heavy platform delivers in industrial conditions.
Built for miles, designed for payload.
With added weight on its back the B2 keeps a steady gait: the basis for long deployments with sensor or tooling payloads.
One platform. Two ways to move.
Where the surface shifts from concrete to gravel, mud or debris, the B2 holds its course and pace, correcting each leg within milliseconds.
Key features
Go Beyond the Limits - Leading Industrial Applications
Beyond the Limits of Motion
Fastest running industrial-grade quadruped robot at 6m/s. Excellent terrain adaptability to ensure stable travel on slippery or uneven surfaces, climbing stairs as if they were flat. Effortlessly tackling steps while remaining extremely stable and balanced.
Extreme Joint Performance
170% increase in joint performance with 360 N·m of torque. Extreme performance provides greater flexibility and stability for industrial operations. Superior obstacle-crossing ability, easily crossing wooden piles, 40cm high platforms and other obstacles.
Breakthrough Endurance and Load
100% increase in sustained load and 200% increase in endurance. Continuous walking with a load greater than 40kg. Unloaded continuous walking endurance greater than 5 hours with more than 20km mileage. With a 20kg load, continuous walking can last for more than 4 hours.
Wheeled-Legged Form & Versatile Power
Innovative structural design of the B2 realizes switching between legged and wheeled forms (optional). The battery supports quick change and autonomous charging solutions (optional), suitable for a wide range of industrial scenarios.
Industrial Intelligence in All Scenarios
IP67 ingress protection for all-scene adaptation. Ideal for emergency rescue on all-terrain, industrial inspection with 3D mapping and infrared scanning, and power inspection with intelligent power solutions.
B2-W: go further with higher efficiency
The B2-W puts the same industrial platform on wheel-legs: 15 km/h, around 85 kg of its own weight, a 120 kg standing load and up to 25 km of range with a 40 kg payload. Wheels for speed and efficiency on flat and semi-rough ground, full legged gait where wheels cannot go.
Options & industrial configurations
The Unitree B2 and B2-W can be built around your organisation's specific mission. From autonomous inspection with LiDAR, thermography and gas detection to manipulation with a robotic arm and fully automated inspection rounds.
