Canonical robot record
Overview
The Unitree B2 is an industrial-grade quadruped robot developed by Unitree Robotics (Hangzhou Yushu Technology) and released in 2023 as the successor to the B1. It is positioned for heavy-duty commercial and industrial use such as inspection, logistics transport, and emergency operations in challenging environments.
The B2 emphasizes strength and endurance, with high standing and walking load capacity, long battery runtime, and rugged ingress protection that lets it operate outdoors and in harsh conditions. Its front and rear depth and optical cameras provide long-range perception with strong anti-interference performance.
The platform is built for demanding terrain, able to cross obstacles, climb stairs, and ascend steep slopes. An optional configuration allows the B2 to switch between a legged form and a wheeled (B2-W) form for greater speed and flexibility.

Record changelog
- Payload Capacity: 120 kg changed to ≥ 120 kg (standing); > 40 kg (continuous walking) · Jul 8, 2026
tranche-4 verification (corrected): Bare '120 kg' launders the standing qualifier: 120 kg is static standing load; continuous walking payload is > 40 kg.
- Battery Life: 240 min changed to 4–6 h (unloaded walking > 5 h / > 20 km; with 20 kg load > 4 h / > 15 km) · Jul 8, 2026
tranche-4 verification (corrected): Official battery life '4-6h' (45 Ah / 2250 Wh, 58 V). Stored 240 min keeps only the loaded lower bound and drops the range and load qualifiers. numeric_value = lowe
- Sensors: LiDAR, stereo cameras, ultrasonic sensors, IMU changed to 3D LiDAR ×1, depth cameras ×2, optical cameras ×2 · Jul 8, 2026
tranche-4 verification (corrected): Official published sensing config: '3D LiDAR x1 + Depth camera x2 + Optical camera x2' (front/rear). Ultrasonic sensors are not in the published configuration; IMU
- Height: 600 mm changed to ≈645 mm (standing) · Jul 8, 2026
tranche-4 verification (corrected): Official standing size ≈ 1098 x 450 x 645 mm. Spec row (600) contradicts both the official page and core height_mm=645.
