Smooth, Dynamic Motion Control

Powered by high-performance joint modules developed by Unitree, the B2-W moves with remarkable responsiveness and precision. It accelerates quickly, performs agile maneuvers such as jumps, turns, and even two-leg movement, and adapts fluidly to changing terrain. Its integrated control system combines perception and locomotion, helping the robot stay stable, confident, and predictable even at higher speeds.

Built for Challenging Terrain

The UNITREE B2-W is designed for environments with uneven, loose, and constantly changing surfaces. It can move across grass, stones, gravel, rough paths, and more, while its fast and precisely coordinated joints help maintain strong balance and traction. The robot can climb stairs 20–25 cm high, move up and down obstacles up to 40 cm in the direction of travel, and handle slopes steeper than 45°, making it a great choice for rugged outdoor use.

Fast Travel Over Long Distances

Thanks to its wheel-driven locomotion system, the B2-W can reach speeds of up to 15 km/h while maintaining excellent stability and control. Its 225 mm wheels can operate at up to 50 rad/s and generate maximum torque of 40 N·m, helping the robot cover long distances quickly and smoothly.

Impressive Payload Capacity

The B2-W stands out with its strong load-handling capability. In a static position, it can support up to 120 kg, and while moving it can carry payloads over 40 kg. That makes it a practical mobile platform for transporting tools, equipment, sensors, or supplies in hard-to-reach areas. Whether you are experimenting, testing field robotics, or building advanced transport solutions, this robot gives you plenty of room to work.

Long Runtime for Extended Missions

Equipped with a high-capacity 45 Ah, 58 V battery, the UNITREE B2-W is ready for extended operation. With a 40 kg payload, it can travel up to 25 km. In the specification table, the maximum no-load operating time is listed as over 4 hours with a range of up to 70 km. This makes the platform especially attractive for long sessions in the field, advanced hobby projects, and demanding real-world testing.

Advanced Environmental Perception

The robot uses a powerful sensor suite that includes a 32-beam automotive-grade LiDAR, a depth camera, and a high-resolution optical camera. This setup provides precise environmental awareness, enabling safer and more reliable navigation on stairs, slopes, and uneven terrain. For users developing autonomous functions or advanced robotics workflows, this sensing package creates a strong foundation.

Strong Computing Power and Expandability

The standard configuration includes an Intel Core i5 processor for platform functions and an Intel Core i7 processor for user development and application deployment. The system can also be expanded with additional computing modules, including Jetson Orin NX, allowing you to implement more advanced AI, vision, and autonomy solutions. OTA software update support helps keep the robot’s capabilities up to date over time.

Ready for Tough Conditions

The B2-W is made for challenging environments. Its IP67 rating helps protect it against dust and water, while the operating temperature range from -20°C to 55°C supports reliable performance in a wide variety of weather and field conditions.

Perfect for Exploration, Testing, and Advanced Robotics Projects

The UNITREE B2-W is a great fit for inspection tasks, search-and-rescue style experiments, mobile cargo transport, and work in hard-to-access locations. Its combination of speed, payload capacity, intelligent perception, and long operating range makes it a standout platform for enthusiasts and professionals looking for a powerful quadruped robot with wheels. If you want a machine that can go farther, carry more, and handle terrain that stops ordinary platforms, the B2-W is built for the challenge.
