Unitree A2-W Review Summary
The A2-W puts 190 mm wheels on the A2. It weighs about 52 kg, moves at up to about 6 m/s and covers about 35 km in more than 3.5 hours without load, or about 15 km carrying 25 kg. Dual batteries are hot-swappable, so a pack can be changed without shutting down. Joints of about 180 N·m let it climb 30 cm stairs and obstacles of 0.5 to 1 m. The base version is IP56 with one LiDAR; the PRO has two LiDARs and core components to IP67. Compared with the legged A2 it is faster and ranges further, with shorter endurance in hours.
Pros
About 6 m/s and 35 km
Hot-swappable dual batteries
180 N·m joints
Rich interfaces
PRO version to IP67 on core components
Cons
Shorter endurance in hours than the legged A2
Second LiDAR only on the PRO
Who It Is For
It fits inspection and logistics users on large sites who need speed and range with the ability to climb.
