The Unitree As2 PRO is the field-deployment-focused configuration of the Unitree As2 quadruped robot series, developed by Unitree Robotics to deliver enhanced endurance, payload capacity, and perception capability over the entry AIR variant. Weighing approximately 18 kg with its battery, it shares the same compact 12-DOF mechanical platform with low-inertia inner-rotor PMSM motors and industrial-grade crossed roller bearings, while stepping up to 75 N·m peak joint torque, a standing payload of up to 55 kg, and a continuous walking load of approximately 13 kg. The robot operates at speeds between 0 and 3.7 m/s in standard use and handles slopes up to 40 degrees and stairs up to 25 cm in height. An IP54 protection rating and a -20°C to 50°C operating range make it well-suited for sustained deployment across outdoor industrial sites, patrol routes, and mixed-environment field operations.
The As2 PRO upgrades the sensor stack with an industrial-grade 64–128-line LiDAR and the ISS 3.0 Intelligent Follow System, enabling centimeter-level positioning for stable autonomous following and navigation in complex environments. An HD camera, speaker, microphone, front lighting, and Wi-Fi 6 and Bluetooth 5.2 connectivity complete the onboard suite, while optional GPS and 4G connectivity can be activated with user authorization for expanded field communication. The long-range 15,000 mAh battery delivers approximately 4 hours of unloaded continuous walking over around 20 km, with over 2.5 hours available when carrying a 13 kg payload. Backed by the UniStore application platform and continuous OTA software updates, the As2 PRO is well-positioned for inspection operators, security integrators, and field teams seeking a durable, sensor-equipped legged platform without the overhead of full secondary development.

Model Features
High-Torque Joint System
Low-inertia inner-rotor PMSM motors with industrial crossed roller bearings and dual encoders per joint deliver up to 75 N·m peak torque, supporting a standing payload of 55 kg and a continuous walking load of 13 kg.
Long-Range Endurance
The 15,000 mAh long-range battery with fast charging (51V 9A) delivers approximately 4 hours of unloaded continuous walking over around 20 km, with over 2.5 hours and approximately 13 km available when carrying a 13 kg payload.
Industrial Perception & Following
Industrial 64–128-line LiDAR, HD camera, and the ISS 3.0 Intelligent Follow System enable centimeter-level positioning, autonomous navigation, and stable side-follow across complex indoor and outdoor environments.
IP54 All-Weather Protection
An IP54 dust and rain protection rating combined with a -20°C to 50°C operating range keeps the As2 PRO running reliably across outdoor industrial sites, patrol routes, and mixed-environment deployments in challenging weather conditions.
Use Cases & Application Scenarios
With IP54 protection, industrial LiDAR, ISS 3.0 following, and 4-hour endurance, the As2 PRO is built for sustained real-world deployment across inspection, patrol, and field operations.
Industrial Inspection
The As2 PRO is well-suited for autonomous patrol and inspection of facilities such as power plants, substations, pipelines, and manufacturing floors. Its IP54 rating, wide operating temperature range, and industrial LiDAR-equipped navigation allow it to cover complex multi-kilometer routes reliably in challenging weather and lighting conditions.
Security Patrol & Surveillance
The As2 PRO combines ISS 3.0 autonomous following, HD camera imaging, and optional 4G connectivity to support perimeter security and site surveillance workflows. Its compact form factor enables navigation through corridors, doorways, and mixed indoor and outdoor patrol routes across a full shift without recharging.
Outdoor Navigation & Field Operations
With gradeability of up to 40 degrees, the ability to climb 25 cm stairs, and a no-load range of approximately 20 km, the As2 PRO handles unstructured outdoor terrain for terrain mapping, environmental monitoring, and field data collection across challenging landscapes.
Research & Education
Universities and robotics labs seeking a deployment-ready legged platform with industrial-grade sensing can use the As2 PRO to run inspection and mobility experiments via the UniStore ecosystem, without requiring custom development infrastructure. Its enhanced payload and endurance over the AIR variant make it a practical upgrade for more demanding research scenarios.
