Unitree B2-Ex
Explosion-proof quadruped robot — intelligent security sentinel
Continuous OTA software upgrades and updates. Robots take on the risk; people stay safe.
Key parameters
Highlighted payload, mobility, and protection values for high-risk environments.
Load capacity
High payload capacity.
Mobility
Slope climbing and step negotiation.
Protection
Ingress protection rating.
The 25 cm step value is presented as a marketing parameter on this summary card; the detailed table lists a range of 20–25 cm.
Safety first
In line with the safety principle, independent certification requirements apply to key components, including the power supply system and motors. Source control and rigorous processes aim to establish a safety defense line in high-risk scenarios.
Integration for industrial applications
Pan-tilt-zoom (PTZ) units, visible-light cameras, infrared thermal cameras, gas cloud imaging and acoustic imaging systems can be integrated, along with various field payloads such as communication modules, gas sensors, LiDAR and robotic arms. Multi-payload integration supports multidimensional perception and comprehensive monitoring of critical parameters with a single robot.
Reach deeper into industrial sites and extend inspection boundaries
Designed for high-risk industrial environments such as natural gas gathering stations, oil and gas production facilities, chemical tank farms and hazardous material warehouses. Its route-based patrol, equipment condition data collection and anomaly identification support help reduce how often personnel need to enter hazardous areas. Functions and configurations can be adapted to site explosion protection zones, road conditions and inspection requirements.
