The Shezen-based company announced the As2 on its website on Tuesday, offering the robot dog in three variants — Air, Pro and Edu.
Weighing about 18 kilograms with its battery, the machine's standout feature is its pace: the Air version reaches a top speed of 3.0 meters per second, while the Pro and Education models hit 3.7 m/s, climbing to 5 m/s under no-load conditions.
The As2 also delivers notable endurance, covering around 20 kilometers on a single charge over four hours without a load. Even carrying about 15 kilograms of payload, it can operate for over two and a half hours and travel more than 13 kilometers with its maximum batter capacity of 15000mAh.
Agility is another hallmark of the new model. The As2 can scale 25-centimeter stairs, traverse slopes of up to 40 degrees and mount vertical ledges as high as 50 centimeters, making it suited for rugged outdoor terrain as well as indoor staircases.
Unitree is one of China's leading robotics companies, producing both quadruped robots and humanoid machines. The firm gained global attention last year when its humanoid robots performed a synchronized dance alongside human performers during the Spring Festival Gala, China's most-watched television broadcast.
Its humanoid robot H1 returned to the gala stage this year, showcasing a martial arts routine featuring complex maneuvers that underscored the company's rapid advances in robotic mobility and control.
