Unitree As2 Series Robot Dogs: Robust Bionics and Autonomy in Three Tailored Performance Classes

The Unitree As2 Series is aimed at industrial companies, research institutions, educational organizations, and development teams seeking a highly agile, compact, and powerful quadruped robotic platform. With a light total weight of approx. 18 kg, high-precision crossed roller bearings, and powerful joint motors, the series sets new standards in the field of compact bionic robots. The decisive unique selling point (USP) lies in the tailored variety of variants: From the cost-efficient base variant As2 Air to the all-weather inspection solution As2 Pro, and on to the uncompromising development platform As2 X with secondary development support and optional charging dock compatibility, the series offers the optimal hardware adaptation for every deployment scenario.

Highlights of the Unitree As2 Platform (Base Features)

• Compact Bionic Design: Lightweight aluminum alloy and high-strength engineering plastic chassis with a total weight of only approx. 18 kg (incl. battery).
• High-Performance Joint Actuators: 12 degrees of freedom with low-inertia permanent magnet synchronous joints, industrial-grade crossed roller bearings, and extremely wide movement angles.
• Modern Onboard Computing Base: Integrated 8-core high-performance CPU for precise control of complex walking patterns and real-time motion sequences.
• Comprehensive Interaction Suite: Integrated Wi-Fi 6, Bluetooth 5.2, microphone array, speakers, lighting, and HD camera for seamless communication in the field.
• Future-Proof Ecosystem: Full support for the UniStore application platform as well as continuous Smart OTA updates for the long-term expansion of system functions.

Highlights of the Model Variants (Air, Pro & X Edition)

• Unitree As2 Air: The cost-efficient entry-level variant with L2 LiDAR, 65 Nm torque, 8,000 mAh battery, and up to 2 hours/10 km range in unloaded operation.
• Unitree As2 Pro: The professional inspection platform with industrial wide-angle LiDAR (64–128 lines), 75 Nm torque, IP54 protection rating, GPS, 4G connectivity, and ISS 3.0 Follow Mode.
• Unitree As2 X: The high-end developer model with superior 90 Nm torque, up to 5 m/s top speed, full secondary development (Isaac Sim), and optional docking station compatibility.
• Integrated Telemetry (Pro & X): Factory-installed GPS and 4G module for autonomous outdoor navigation and worldwide data transmission.
• Maximized Endurance (Pro & X): 15,000 mAh extended-range battery with fast charger (51V 9A) for over 4 hours of runtime (20 km range) unloaded and 2.5 hours with 13 kg payload.

Technical Specifications in Variant Comparison

Advantage for professionals: The Unitree As2 Series offers maximum flexibility with an excellent price-performance ratio. While the Air version convinces as a cost-efficient entry point and the Pro version with IP54, GPS, 4G, and 15,000 mAh battery is the ideal choice for autonomous inspection tasks, the X version sets new standards for demanding robotics research and industrial integration with 90 Nm torque, secondary developer support (Isaac Sim), and charging dock options.
