Unitree A2-W is the wheeled variant of the Unitree A2 platform, combining the A2's powerful legged locomotion with integrated wheel units for efficient, high-speed travel on flat and semi-structured terrain. On smooth surfaces the A2-W rolls quickly and quietly, consuming less energy; when encountering obstacles, stairs, or rough ground, it transitions seamlessly to full quadruped stepping. Sharing the A2's dual LiDAR perception, IP56 weather resistance, and advanced dynamic control, the A2-W extends the platform's operational suitability to logistics routes, large indoor and outdoor campuses, and inspection workflows where travel efficiency matters as much as terrain adaptability.
Key Highlights

- Dual LiDAR; IP56 water resistance; outdoor and mixed-terrain capable
- Seamless transition between rolling and stepping modes based on terrain
- Higher energy efficiency and range on flat surfaces compared to legged-only A2
- Suited for logistics, campus inspection, and large-area patrol deployments
- Open secondary development with Unitree SDK; ROS2 compatible
