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 - The authors propose UniLM-Nav, a unified framework for zero-shot open-vocabulary last-mile navigation. It then grounds task-relevant affordance point in the selected view and lifts the result into the robot-centric coordinate frame.

  • Interactive Navigation for Legged Manipulators with Learned Arm-Pushing Controller

    2025-03-03 - Research Publication - The paper introduces a novel interactive navigation framework for legged manipulators, featuring an active arm-pushing mechanism that enables the robot to reposition movable obstacles in space-constrained environments. This is because the pushing controller is a closed-loop feedback controller that adapts its actions in real time according to the object’s pose.
