The Unitree A2 is Unitree's industrial-grade quadruped for heavy, long-range field work. Twelve high-power-density joint motors deliver around 180 N·m of peak torque, enough to carry a 25 kg continuous walking load (about 100 kg standing) at 0–3.7 m/s, with bursts up to ~5 m/s. It climbs 45° slopes, takes 30 cm steps and scales obstacles of roughly 0.5–1 m, operating from -20°C to 55°C.

A hot-swappable dual-battery system (2 × 9000 mAh, 907 Wh) gives more than 5 hours / ~20 km unladen, or over 3 hours / ~12.5 km with 25 kg aboard, and a pack can be changed without stopping the mission. The Standard version carries an industrial LiDAR and an HD camera for obstacle avoidance and point-cloud surround view, an 8-core platform CPU plus an Intel Core i7 for your own development, Wi-Fi 6, Bluetooth 5.2 and IP56 protection. RS485, CAN, Gigabit Ethernet, USB-C and 12/24 V power outputs make payload integration straightforward; secondary development (Isaac Sim) and OTA updates are supported, with a 12-month warranty.
