Elevating the standard B2 with an innovative optional wheeled foot design, the Unitree B2-W Robot Dog quadruped achieves hybrid mobility by effortlessly switching between legged and wheeled modes, breaking through endurance barriers on extended patrols and flat terrains while maintaining the core B2's superior specs like >6m/s speed, 360N.m torque, and 120kg standing payload. This key differentiator enhances versatility for industrial applications such as long-distance power line inspections or emergency response on mixed surfaces, allowing seamless transitions from steep 45° slopes and 40cm obstacles in legged form to efficient rolling traversal in wheeled mode, all powered by the same 45Ah battery for 5+ hours of operation and fortified with IP67 protection against harsh conditions. By integrating advanced sensors including 3D LiDAR and depth cameras for precise environmental perception, the B2-W outperforms traditional quadrupeds by two to three times in load and motion capabilities, positioning it as the ultimate adaptive solution for demanding, multi-scenario robotics deployments.
The Unitree B2 Robot Dog stands out as the fastest industrial-grade quadruped robot available, achieving speeds exceeding 6m/s while delivering unmatched terrain adaptability for seamless navigation across slippery, uneven surfaces, and obstacles up to 40cm high. Engineered with a robust 360N.m joint torque -- representing a 170% performance boost over predecessors -- this robot dog excels in continuous stair climbing on 20-25cm steps and forward traversal of 40cm stairs with exceptional stability, making it ideal for demanding industrial inspection and power patrol applications. Its innovative optional wheeled foot design allows effortless switching between legged and wheeled modes, enhancing versatility in dynamic environments like emergency rescue operations on steep slopes over 45° or rocky terrains.
Equipped with a high-capacity battery, the Unitree B2 offers extended endurance of over 5 hours of unloaded walking -- covering more than 20km -- while supporting a standing load of up to 120kg and continuous walking with over 40kg payloads for more than 4 hours. Advanced sensors, including 3D LiDAR, dual depth cameras, and optical cameras, combined with infrared scanning for 3D mapping, enable precise environmental perception and AI-driven autonomy, powered by Intel Core i7 processors for seamless OTA updates and secondary development. With IP67 ingress protection and operation in temperatures from -20°C to 55°C, this all-terrain robot dog redefines industrial efficiency as a ubiquitous assistant for power inspections, emergency rescues, and beyond, outperforming global competitors by two to three times in load, endurance, and motion capabilities.
