Unitree A2 Review Summary
The A2 is built around endurance. Two battery slots give 907 Wh, enough for more than five hours of continuous walking, about 20 km, without load, or more than three hours carrying 25 kg. Joints deliver about 180 N·m, the robot climbs 30 cm steps and 45-degree slopes, and it works from -20 to 55 °C. Two versions are offered: the A2 with one LiDAR and IP56, and the A2-PRO with two LiDARs and core components sealed to IP67.
Pros
More than 5 hours of walking
Dual batteries
25 kg walking load at 42 kg weight
Wide temperature range
Rich interfaces for payloads
Cons
Base version IP56 only
Second LiDAR only on the PRO
Who It Is For
It fits inspection operators and integrators who need more endurance and payload than a small robot dog without the weight of the B2.
