New four-legged robot balances endurance, speed, and strength for industrial deployments
Unitree Robotics has announced its latest quadruped robot, the A2, just one week after unveiling its affordable humanoid R1. Designed for real-world applications such as inspection, logistics, and research, the A2 combines upgraded perception with agility and strength.
Weighing 37 kg, the A2 can carry up to 25 kg while walking continuously for three hours or 12.5 km, supported by hot-swappable batteries for extended missions. It achieves a top speed of 5 m/s and can climb obstacles up to 1 meter, outperforming many quadrupeds in its class.
Key upgrades include dual lidar sensors, an HD camera, and a front light, offering 360° depth awareness and eliminating blind spots. This marks a step up from its predecessor, the B2, which was heavier and less agile.
With its improved mobility and sensing, Unitree said the A2 is purpose-built for industrial deployment, with pricing and availability to be announced. The launch underscores Unitree’s rapid expansion in both humanoid and quadruped robotics, following its recent Series C funding that valued the company at $1.7 billion.
