The Unitree As2 series brings industrial capability to a compact, lightweight platform. With 16 powerful joint motors of approx. 95 N·m, a 648 Wh battery and IP54 protection, the As2 is designed for organisations that want to automate inspection, monitoring and data collection without the size of a heavy platform.
The As2 moves entirely on legs. It weighs approx. 18 kg, reaches up to 5 m/s and runs over 4 hours unloaded, making it agile on stairs, loose ground, slopes and in tight spaces.
The As2-W combines the same platform with powered 7-inch wheels. On flat and semi-rough routes it travels quickly and efficiently up to approx. 6 m/s, while its legs still overcome obstacles up to 80 cm and slopes up to 45°. Unloaded it covers more than 30 km per charge.
Both versions can be extended with LiDAR, an HD camera, lighting and a compute module of up to 150 TOPS. Through the SDK and APIs the As2 links to your own software, AI models and industrial systems.

Field footage
Compact, yet built for rough terrain
With its 16 joint motors the Unitree As2 moves smoothly over rocks, slopes, dry grass and through water. IP54 protection means rain and wet ground are no obstacle.
Weighing approx. 18 kg with over 4 hours of unloaded runtime, it carries sensors and cameras to places a heavier platform struggles to reach.
As2-W: the speed of wheels, the strength of legs
The As2-W combines powered 7-inch wheels with active leg kinematics. On flat routes it travels up to approx. 6 m/s, while balancing on two wheels, turning and overcoming obstacles up to 80 cm.
95 N·m joint modules and a standing load of up to approx. 150 kg show how much strength this compact platform holds.
Key features
Powerful Pioneer - Compact Yet Extraordinary
Wherever It Goes, Conquers Every Terrain
The As2-W combines the speed of wheels with the obstacle-crossing capability of legs. It adapts automatically to stairs, gravel and steep slopes, climbing obstacles up to 80 cm and slopes up to 45°.
Powerful Performance, Long Endurance
95 N·m industrial-grade joint modules, 7-inch oversized wheels and a 648 Wh (15,000 mAh) battery. It keeps its climbing performance under heavy load and exceeds 30 km of unloaded range.
Up to 150 TOPS On-board Compute
A high-performance expansion module processes large volumes of data in real time on the robot. Ideal for security, inspection and advanced applications.
Reliable and Robust, Even in Harsh Conditions
Industrial-grade IP54 dust and water resistance withstands rain, dust and wet terrain, ensuring reliable mission completion around the clock.
Open Platform, Empowering Innovation
Developer-friendly SDK and APIs support large AI models for embodied AI interaction and autonomous decision-making. The ISS 3.0 side-follow system tracks the operator with centimetre-level positioning.
