What's in This Configuration
The Unitree As2-W X is a compact yet extraordinarily capable wheeled-leg quadruped robot that combines the high-speed efficiency of wheels with the obstacle-overcoming capability of articulated legs. Built around 16 industrial-grade joint motors with 95 N·m peak torque, it automatically adapts to stairs, gravel, steep slopes, and uneven terrain. The 7-inch oversized wheels (178 mm diameter, 50 mm width) deliver smooth rolling on flat surfaces, while the articulated leg suspension enables climbing obstacles up to 80 cm high and slopes up to 45°. The robot weighs approximately 25 kg with battery and can carry a continuous walking payload of 16 kg — with a maximum standing load of 150 kg. Powered by a 15,000 mAh (648 Wh) lithium-ion battery, it achieves over 3 hours of continuous operation unloaded with a range exceeding 30 km, or over 2 hours with a 16 kg load covering approximately 25 km. The ISS 3.0 Intelligent Side-follow System delivers centimeter-level positioning and stable tracking for hands-free companion operation. An industrial-grade 64–128-line ultra-wide-angle LiDAR and HD front camera provide rich environmental perception for autonomous navigation and obstacle avoidance. The 8-core high-performance CPU handles real-time control and AI processing on board. The IP54 protection rating ensures reliable operation in rain, dust, and wet terrain from −20°C to 50°C. Full Wi-Fi 6 and Bluetooth 5.2 connectivity, plus a speaker, array microphone, and front lighting enable voice interaction and remote command. A handheld remote controller is included for manual operation. The UniStore Application Platform and Smart OTA Updates keep the robot continuously improving.

Wherever It Goes, Conquers Every Terrain
The As2-W X combines the high-speed efficiency of wheels with the obstacle-overcoming capability of legs, automatically adapting to stairs, gravel, and steep slopes. It traverses complex terrain with ease, climbing obstacles up to 80 cm high and slopes up to 45°. The 7-inch oversized wheels (178 mm diameter, 50 mm width) provide smooth, fast rolling on flat and paved surfaces, while the articulated leg suspension absorbs shocks and maintains traction on uneven ground. The extensive joint range of motion — body: −45° to 45°, thigh: −115° to 200°, shank: −159° to −47° — enables natural, animal-like gait adaptation for maximum stability and maneuverability across any surface.
Powerful Performance, Long Endurance
The As2-W X is driven by 16 industrial-grade joint modules delivering ~95 N·m peak torque each. Low-inertia, high-speed inner-rotor permanent magnet synchronous motors (PMSM) provide exceptional response speed and heat dissipation. Industrial-grade crossed-roller bearings on every joint ensure high precision and high load capacity under continuous operation. The 15,000 mAh (648 Wh) lithium-ion battery powers over 3 hours of unloaded cruising with a range exceeding 30 km. Even under a 16 kg continuous walking load, the robot maintains over 2 hours of operation covering approximately 25 km. The localized air-cooling system keeps joint temperatures in check during high-intensity missions. With a maximum standing load of 150 kg, the As2-W X can support heavy equipment, supplies, or even a human rider in stationary applications.
Autonomous Side-Follow, Ready to Go With You
The ISS 3.0 Intelligent Side-follow System delivers centimeter-level positioning accuracy and stable tracking, allowing the As2-W X to follow its operator autonomously through complex environments. Whether carrying backpacks and supplies for outdoor exploration, transporting tools across a construction site, or accompanying personnel during inspection rounds, the robot maintains a safe, consistent distance and adapts its speed to the operator's pace. The system leverages the on-board HD camera, LiDAR, and 8-core CPU for real-time person detection, path planning, and obstacle avoidance — no external beacons or GPS required.
Reliable and Robust, Even in Harsh Conditions
Built for real-world deployment, the As2-W X carries an IP54 dust and water resistance rating, withstanding rain, dust, and wet terrain without compromise. It operates reliably across a wide temperature range from −20°C to 50°C, making it suitable for everything from cold-weather outdoor exploration to hot industrial floors. The aluminum alloy + high-strength engineering plastic chassis balances lightweight agility with structural durability. Dual encoders on every joint provide closed-loop precision and fault detection. The robot is engineered for 24/7 mission readiness — whether patrolling perimeters, inspecting infrastructure, or supporting emergency response.
Dual-Sided Perception — Zero Blind Spots
The As2-W X is equipped with a comprehensive sensor suite for full situational awareness. The industrial-grade 64–128-line ultra-wide-angle LiDAR captures dense 3D point clouds of the surrounding environment for SLAM mapping, obstacle detection, and path planning. The HD front camera delivers high-definition video streaming and visual recognition for object detection, person tracking, and terrain analysis. Together with the ISS 3.0 side-follow module, these sensors enable autonomous navigation, intelligent following, and safe operation in dynamic, unstructured environments.
Compact Foldable Design — Go Anywhere
Despite its extraordinary capability, the As2-W X is remarkably compact. In standing configuration, it measures 721 × 493 × 521 mm — small enough to navigate doorways, corridors, and tight spaces. When folded, it compacts to just 768 × 602 × 211 mm, fitting easily into vehicle trunks, equipment cases, or storage lockers for transport and deployment. At approximately 25 kg with battery, it is light enough for two people to lift and position, yet heavy-duty enough to carry substantial payloads and withstand demanding operational conditions.
Open Platform, Empowering Innovation
Unitree provides a mature, developer-friendly SDK and open APIs for the As2-W X platform. The 8-core high-performance CPU runs the real-time control stack, while external interfaces — Gigabit Ethernet ×1, SBUS ×1, and BAT power output — enable integration with custom payloads, sensors, and compute modules. The UniStore Application Platform offers a growing ecosystem of apps and capabilities. Smart OTA Updates ensure the robot continuously improves with new features and optimizations. The platform supports custom development with provided robot models and simulation interfaces, including compatibility with Isaac Sim and other simulation environments for rapid algorithm prototyping and reinforcement learning research. Optional expansion via a computing dock (sold separately) unlocks even greater AI performance for embodied intelligence and autonomous decision-making.
