Unitree Debuts A2 Quadruped Robot With Extended Endurance and Industrial-Grade Design

• The 37kg Unitree A2 Stellar Explorer can walk continuously for up to 5 hours unloaded or 3 hours carrying a 25kg payload.
• Features include dual LiDARs, an HD camera, hot-swappable dual batteries, and operation in temperatures from -20°C to 55°C.

Unitree has introduced the A2 Stellar Explorer, a medium-sized, industrial-grade quadruped robot designed for demanding terrain and extended missions. Weighing approximately 37kg with batteries, the A2 can walk for over 5 hours and 20km unloaded, or 3 hours and 12.5km carrying a 25kg load. It can handle slopes of up to 45°, climb steps up to 30cm, and operate in a wide temperature range from -20°C to 55°C.

The A2 is equipped with two industrial LiDAR sensors, front and rear, alongside an HD camera and integrated front light for dual-sided perception with zero blind spots. A wheel-leg configuration is available as an option, and the robot features a hot-swappable dual-battery system for uninterrupted operation. Its triple power system is built for stability in extreme environments.

Built from aluminum alloy and high-strength engineering plastic, the A2 supports secondary development, offers multiple expansion ports, and includes an Intel Core i7 user computing platform. With a maximum standing load of about 100kg and IP56-rated weather resistance, the A2 is positioned for industries including logistics, inspection, and emergency rescue.

🌀 Tom’s Take:

Unitree has been quite active in its product development. It recently debuted its humanoid robot, R1, for just $5,900 and highlighted how its Go2 quadruped robot is being utilized in agriculture. The A2 Stellar Explorer joins others in its industrial robot line, which is being used for use cases such as substation and mine inspection, and fire rescue solutions.
