The A2 is Unitree's industrial quadruped for outdoor inspection and patrol, sitting between the compact As2 and the heavy B2. It weighs about 42 kg with the battery (35 kg without), stands 820 x 440 x 570 mm, walks at up to 3.7 m/s and can be pushed to roughly 5 m/s. Joint torque of about 180 N·m gives it a continuous walking load of about 25 kg and a standing load near 100 kg. With a single 9000 mAh pack it walks five hours and 20 km unloaded, or more than three hours and about 12.5 km carrying 25 kg; a dual-battery configuration doubles the capacity to 18000 mAh. Perception is one lidar plus an HD camera, and the A2-PRO variant adds a second lidar and raises protection from IP56 to IP67 on core components.
