Overview
About the Unitree A2 range
The A2 sits between Unitree's small Go2 and the heavy B2. It weighs about 42 kg with its battery and can carry about 25 kg while walking. Unloaded it walks for more than 5 hours and about 20 km. It climbs 30 cm steps and slopes of about 45°, and is sealed to IP56. Two hot-swappable battery slots help keep it working. An Intel i7 computer is set aside for user development. The Pro versions add a second, rear LiDAR, IP67 core parts, and built-in GPS, 4G and a follow module. The wheel-legged A2-W adds wheels for faster travel on flat ground. For Irish industrial sites, utilities and research groups, the A2 is a practical size for inspection and carrying jobs.
