Unitree's flagship industrial quadruped, commercial since 2024. The B2 is positioned as a payload-heavy alternative to the inspection-focused robot dogs that came before it, with a 40 kg walking load and a 120 kg static-standing capacity that opens up tool-carrying and equipment-deploy use cases at the worksite.
Standing dimensions are 1098 mm long by 450 mm wide by 645 mm tall, with a prone profile of 880 by 460 by 330 mm for transport. Total weight is 60 kg including the 2250 Wh battery, which delivers more than 5 hours of unloaded endurance over a 20 km range. Under a 20 kg working load, the platform still delivers more than 4 hours and a 15 km range — the working spec that matters for a full shift at a site.
The motion stack tops out at 6 m/s in forward running, with a 40 cm maximum stair-climb height and 45 degree slope capability. IP67 sealing delivers full water submersion tolerance, across an operating temperature window of -20 to 55 C.
Onboard compute starts with an Intel Core i5; configurations can add an Intel Core i7 and up to three NVIDIA Jetson Orin NX modules for autonomy workloads. The sensor stack ships with one 3D LiDAR, two depth cameras, and two optical cameras. Headline pricing from Unitree's storefront is 100,000 USD, with regional duties and shipping additional.
