The Unitree A2-W is a wheel-legged variant of the A2 industrial platform, measuring 900 by 440 by 625 mm standing and weighing approximately 52 kg with dual batteries. It features 16 joint motors with approximately 180 N·m maximum torque on 190 mm diameter wheels, reaching speeds from 0 to 6 m/s. The hot-swappable dual-battery system (single 9,000 mAh / 453.6 Wh) provides over 3.5 hours unloaded (approximately 35 km) and over 1.5 hours with 25 kg load (approximately 15 km). Standing load reaches approximately 100 kg with continuous walking load of approximately 25 kg (up to 35 kg ideally). It climbs 30 cm stairs, 45-degree slopes, and 0.5 to 1 m obstacles. The standard A2-W includes 1 LiDAR and 1 HD camera, while the PRO adds dual LiDAR, GPS, 4G, wireless vector follow, and IP67 core components. External interfaces include RS485 x2, CAN x2, Gigabit Ethernet x2, USB 3.0 Type-C x4, and multi-voltage power outputs. An 8-core CPU plus Intel Core i7 with optional high-compute expansion dock handle processing. IP56 rated. Continuous OTA upgrades and secondary development are supported. Targets industrial inspection, park logistics, and emergency rescue.
