About

About B2

Unitree B2 is an industrial quadruped built for inspection and payload carriage across stairs, slopes and uneven ground. The 60 kg robot runs at more than 6 m/s in special configurations, crosses obstacles up to 40 cm and climbs slopes above 45 degrees. Its standing load is at least 120 kg, while continuous walking load exceeds 40 kg. An optional wheeled-foot configuration is a B2 variant, not a separate base product.

The 2,250 Wh plug-in battery supports more than five hours or 20 km of unloaded walking. With a 20 kg load, Unitree specifies more than four hours and 15 km. Standard perception combines one 3D lidar, two depth cameras and two optical cameras, with Intel user compute and multiple Ethernet, USB and power interfaces for mission payloads. IP67 protection and a -20 to 55 °C operating range support industrial deployment.

  • UniLM-Nav: A Unified Framework for Zero-Shot Last-Mile Navigation

    2026-07-07 - Research Publication - Mobile manipulation requires a robot to navigate to a target object or receptacle and then perform intended manipulation. However, reaching the vicinity of the target does not guarantee a manipulation-ready base pose, a problem known as last-mile navigation. Prior methods for last-mile navigation either rely on manual pose annotation or task-specific training, limiting their scalability to open-vocabulary settings wi
