Unitree B1

by Unitree Robotics

Released: 2022

💰 USD 100,000

The Unitree B1 is an industrial-grade quadruped robot designed for demanding applications in agriculture, industrial operations, security patrols, surveys, exploration, and public rescue. With its IP67/IP68 waterproof rating, the B1 operates reliably in all-weather conditions including heavy rain and water immersion up to 1.2 meters. The robot features exceptional load capacity with a maximum standing payload of 80 kg and continuous walking load of 20 kg, making it suitable for cargo delivery and logistics in challenging terrain. Equipped with 12 degrees of freedom (3 per leg), advanced force control technology, and five Intel RealSense D430 depth cameras, the B1 demonstrates superior obstacle-crossing abilities, can climb stairs with 20 cm step heights, traverse slopes up to 35 degrees, and achieve speeds of 1.2-1.8 m/s. Its industrial-grade servo motors deliver 210 Nm maximum torque at the knee joints, enabling complex movements including jumps and backflips. The B1 combines durability, mobility, and computational power through its Intel i5-1135G7 processor and three Jetson Xavier NX platforms, making it a versatile solution for industrial automation and emergency response scenarios.
