With the Unitree A2, Unitree Robotics introduces the next generation of mobile robotics. The A2 uniquely combines the maneuverability of the Go2 and the robustness of the B2, setting new standards for modern robot technology. Whether in industrial, inspection or extreme outdoor scenarios, the A2 is not just a machine, but a reliable, versatile partner that can take on the challenges of any environment.

Design & performance

The A2 impresses with its compact dimensions and high performance:

• Dimensions: 820 × 440 × 570 mm (upright), 720 × 550 × 220 mm (folded)

• Weight: approx. 37 kg incl. dual battery

• Payload: Up to 25 kg regular, up to 100 kg maximum

• Range: Up to 20 km without load (approx. 5 hours), 12.5 km with full payload

• Speed: Up to 5 m/s, incl. climbing stairs and dynamic maneuvers

• Off-road capability: inclines up to 45°, obstacles up to 1 m, stairs up to 30 cm

Thanks to state-of-the-art drive technology with permanent magnet synchronous motors and high-precision dual sensor encoders, the A2 offers exceptional agility and sensitive control, making it ideal for a wide range of applications.
