The Unitree B2 is an industrial-grade quadruped robot released in November 2023. It is positioned above Unitree's consumer Go2 line and targets applications in power-grid inspection, petrochemical facilities, factory floors, and search-and-rescue operations — anywhere that demands a legged robot capable of handling real-world terrain over extended periods without needing to recharge.
At approximately 60 kg with battery included, the B2 is a substantially built machine. Its joint torque reaches 360 N·m — a 170% increase over Unitree's previous industrial platform — which translates into genuine load-carrying capability. The standing load of 120 kg means the B2 can support payloads heavier than itself, while the continuous walking load of 40 kg allows sensors, cameras, communication relays, or tool heads to be carried across kilometres of terrain. Endurance unloaded exceeds 5 hours and 20 km; with a 20 kg load, it manages more than 4 hours and 15 km.
The B2 is IP67-rated for dust and full water immersion, operates from −20°C to 55°C, and ships with a 3D LiDAR, two depth cameras, and two optical cameras as standard. Compute is handled by dual Intel Core processors — an i5 for the platform and an i7 for user-accessible development — with an optional Jetson Orin NX (up to three devices) for applications requiring GPU inference. The interface panel provides four 1000M Ethernet ports, four USB 3.0 ports, and multiple power outputs for powering attached payloads directly from the robot's battery.
A wheeled-legged variant, the B2-W, is also available. It replaces the standard feet with wheel units, allowing the B2 to switch between legged locomotion for rough terrain and wheeled rolling on flat surfaces — useful for deployments that mix factory floors with outdoor or multi-level environments. The core platform is available for direct purchase from Unitree's online shop and through authorised resellers.
