Released: 2023

Overview

The Unitree B2 represents a significant evolution in industrial quadruped robotics, bridging the gap between research platforms and deployment-ready commercial solutions. As Unitree's most capable industrial robot to date, the B2 combines exceptional payload capacity with advanced environmental protection, making it suitable for demanding real-world applications where traditional wheeled robots cannot operate effectively.

Designed from the ground up for industrial use cases, the B2 features a reinforced chassis and an IP67 waterproof rating that allows it to operate in rain, dusty environments, and even wade through water. With a 60kg body weight supporting up to 120kg of payload, the robot can carry inspection equipment, delivery packages, or specialized tools while maintaining stable locomotion across challenging terrain.

The B2's advanced control system enables autonomous navigation through complex environments including stairs, gravel paths, and uneven surfaces. Its integration of multiple sensor systems including LiDAR and stereo depth cameras allows for real-time mapping, obstacle avoidance, and precise path planning, making it a versatile platform for inspection, security patrol, and last-mile logistics applications.

Applications

The Unitree B2 serves critical roles across multiple industrial sectors where mobility and environmental resilience are paramount. In manufacturing facilities and power plants, it conducts autonomous inspection rounds, carrying thermal cameras, gas detectors, or other specialized sensors to identify equipment anomalies and safety hazards. Security and patrol applications benefit from the B2's ability to navigate complex outdoor terrain while carrying surveillance equipment, providing persistent monitoring of perimeters, construction sites, and critical infrastructure.

Logistics and material handling operations deploy the B2 for last-mile delivery in challenging environments such as construction sites, mines, and outdoor industrial facilities where conventional delivery vehicles cannot access. The robot's high payload capacity also makes it suitable for transporting tools, parts, and supplies across factory floors, warehouses, and outdoor yards, reducing the need for human workers to traverse hazardous or fatiguing routes.

Technical Highlights

The B2's mechanical design showcases significant engineering achievements in load-bearing quadruped locomotion. Its high-torque joint actuators and reinforced leg structures enable a 2:1 payload-to-body-weight ratio, exceptional among commercial quadruped robots. The robot's gait control algorithms maintain stability even when carrying asymmetric loads or traversing uneven terrain, while active compliance allows it to adapt to ground irregularities in real-time.

The environmental sealing system represents a major advancement, achieving IP67 protection without compromising heat dissipation from motors and electronics. Advanced sensor fusion combines LiDAR point clouds with stereo depth camera data for robust perception in varied lighting and weather conditions. The onboard computing platform processes navigation and control algorithms locally, enabling autonomous operation without constant network connectivity, while 4G and WiFi options support remote monitoring and fleet management when needed.
