Unitree B2 — Go Beyond the Limits
The Unitree B2 is the world’s fastest industrial-grade quadruped robot, reaching speeds exceeding 6 m/s while carrying heavy payloads across the most demanding terrain. With 360 N·m of peak joint torque, IP67 ingress protection, a 2,250 Wh swappable battery and an onboard Intel processing stack open for third-party development, the B2 is engineered for power inspection, emergency rescue and industrial inspection missions that no conventional robot can handle.

Fastest Industrial Quadruped — Over 6 m/s
The B2 holds the title of fastest industrial-grade quadruped robot on the market, achieving running speeds exceeding 6 m/s in special configurations. Despite this extreme speed, it maintains excellent terrain adaptability, remaining stable and balanced on slippery, uneven and debris-covered surfaces. It climbs stairs effortlessly and sustains stable locomotion across all outdoor industrial environments — delivering rapid response capability that conventional robots simply cannot match.
360 N·m Peak Torque — 170% Joint Performance Upgrade
The B2’s joint system delivers approximately 360 N·m of peak torque — a 170% improvement over its predecessor — providing the raw power needed for dynamic industrial operations. This extreme joint performance translates directly to superior stability under load, faster terrain response and the ability to recover from unexpected pushes or ground irregularities without losing mission continuity. The result is a robot that is simultaneously more forceful and more precise.
Superior Obstacle Crossing — Up to 40 cm Platforms
The B2 crosses obstacles that stop other robots in their tracks: wood pile debris fields, 40 cm high platforms, steep slopes above 45° and ditches up to 1.2 m wide. It handles continuous stair climbing of 20–25 cm steps in forward direction, ascending and descending 40 cm steps without hesitation. This obstacle-crossing capability makes the B2 deployable in post-disaster rescue environments, construction sites and industrial facilities where the terrain is never predictable.
Ultra Load Capacity — 120 kg Standing, 40+ kg Walking
With a standing load capacity of at least 120 kg and a continuous walking load exceeding 40 kg, the B2 can carry full sensor payloads, inspection equipment and tool packages without compromising gait or stability. This represents a 100% increase in sustained load over previous-generation industrial robots. Whether deployed with a mounted LiDAR array, thermal camera, gas detection module or robotic arm, the B2 provides a stable, powerful mobile platform.
Ultra Long Endurance — 5+ Hours, 20+ km Unloaded
The B2’s 45 Ah (2,250 Wh) battery pack delivers unloaded endurance exceeding 5 hours and 20 km of continuous walking — a 200% increase over previous benchmarks. Even with a 20 kg payload, the B2 sustains over 4 hours and 15 km of operation on a single charge. The battery supports both quick-change swapping and autonomous charging solutions (optional), enabling true 24/7 continuous deployment in mission-critical inspection programmes without operator intervention.
Wheeled & Legged Forms — B2-W Variant
The B2-W variant introduces an innovative structural design that allows switching between pure legged locomotion and wheeled-legged hybrid mode, breaking through endurance limitations even further. On smooth industrial floors and paved surfaces, the wheeled mode provides faster, more efficient transit; on rough terrain and stairs, the legged mode takes over. This dual-form capability makes the B2-W exceptionally versatile across mixed-environment industrial campuses, power plants and logistics facilities.
Advanced Perception — LiDAR, Depth & Optical Cameras
The B2’s standard sensor suite includes one 3D LiDAR, two depth cameras and two optical cameras, providing comprehensive environmental awareness for autonomous navigation, 3D mapping and real-time obstacle avoidance. The Intel Core i5 handles platform functions while an Intel Core i7 is reserved for user development — with optional expansion to Jetson Orin NX for AI-heavy workloads. Four Gigabit Ethernet ports, four USB 3.0 ports and multiple power rails (12 V / 24 V / BAT) give integrators broad connectivity for custom payloads.
Industrial Applications — Power Inspection, Rescue & Beyond
Unitree designed the B2 around three core industrial missions: power infrastructure inspection (long stairs, rock piles, steep slopes), emergency rescue (infrared scanning, 3D mapping, hazardous environment entry) and general industrial inspection (autonomous patrol, facility monitoring). Its IP67 rating protects all core systems against dust and water ingress, and its −20°C to 55°C operating range covers the full spectrum of Gulf and global industrial environments. The B2 is not just a robot — it is a complete intelligent inspection platform.
