Unitree released its first major robot product of the Year of the Horse, with a small body capable of carrying a 200-pound man.

According to a report by ZDONGXI on February 24th, today, following the popularity of its humanoid robots performing martial arts at the Spring Festival Gala, Unitree Technology has launched its first new robot product - the quadruped robot Unitree As2.

This product is positioned as a lightweight, industry - grade quadruped robot. It is similar in size to the consumer - grade flagship product Unitree Go2, but Unitree claims that "its power performance is approximately twice that of Go2."

Let's directly see what this new robot can do - it can accompany you on a four - hour hike without getting tired, can catch up with an electric bicycle in speed, can carry heavy loads and run in the snow, can wade through puddles that reach its calves, and can even remain steady with a 200 - pound man standing on it. And its own weight is only 18 kilograms, similar to that of a Corgi.

This is the second time in the past two years that Unitree Technology has released a new quadruped robot product. Previously, in August 2025, it released the industry - grade quadruped robot Unitree A2, and in November 2023, it released the industrial - grade quadruped robot Unitree B2. Both are relatively heavy products weighing over 40 kg.

The newly released Unitree As2 is still an industry - grade product, but it is quite lightweight. According to official information, the Unitree As2 weighs 18 kg, has a peak torque of 90 N.m, has a battery life of over 4 hours when unloaded, meets IP54 rainproof standards, can carry a load of 15 kg, has a loaded battery life of over 13 km, and has an open secondary development ecosystem, which can empower industry applications.

Currently, more parameters and the price of the Unitree As2 have not been announced, but we can learn more product details from the released videos.

At the beginning of the video, the Unitree As2 jumps off a car and starts running with a man, showing its lightweight build similar to consumer - grade quadruped robots. The subtitle "Hiking Partner" also indicates that it can be used for sports companionship scenarios.

In terms of weight, the Unitree As2 weighs 18 kg, and the Unitree Go2 weighs about 15 kg, with a difference of only about 3 kg. It can be seen that its build is closer to consumer - grade products. In contrast, the industry - grade product Unitree A2 weighs about 42 kg, and the industrial - grade Unitree B2 weighs about 60 kg, which are not in the same weight class.

Its battery life also has "industry - grade" characteristics - the Unitree As2 is equipped with a large - capacity battery and has a battery life of over 4 hours when unloaded. In contrast, the battery life of the Air, Pro, and X versions of the consumer - grade product Unitree G2 is 1 - 2 hours, and only the EDU version reaches 2 - 4 hours.

At the same time, the Unitree As2 adopts an IP54 rainproof design. From the video footage, it can be seen that the robot can walk smoothly through puddles that reach its calves.

In terms of movement speed, the maximum speed of the Unitree As2 reaches 5 m/s, which is 18 km/h. It runs faster than many ordinary adults and is about as fast as a city electric bicycle. In contrast, the speeds of the Air and Pro versions of the Unitree G2 are 0 - 2.5 m/s and 0 - 3.5 m/s respectively, and only the X and EDU versions reach a maximum speed of 5 m/s.

The Unitree As2 is equipped with a bionic embodied large - model, which reflects its up - to - date algorithm. From the video footage, when the Unitree As2 rushes towards a user in white clothes and the user runs to the right, the Unitree As2 immediately turns and runs in the direction of the user. It is worth mentioning that the movements of the Unitree As2 are smooth without delay, and the video is not speeded up. If this ability is indeed so sensitive, it will be a significant progress in the application of embodied intelligence.

According to Unitree's introduction, this robot can walk freely in complex terrains and harsh environments. As shown in the following animated image, even when carrying a large heavy load, it can walk smoothly and even run on a steep uphill in the snow.

This product has also upgraded the ISS 3.0 Intelligent Companion System. As shown in the following animated image, when the user walks in front, the Unitree As2 can follow the user on its own. We are waiting for more in - depth product information to find out what specific upgrades this companion system has, such as whether it has the ability of intelligent dialogue with a large language model or Agent call, and whether it can more precisely recognize the user's actions and intentions.

Load - carrying capacity is another key indicator that reflects the "industry - grade" characteristics of the Unitree As2. The Unitree As2 weighs 18 kg and can carry a load of 15 kg, and its standing load can reach 65 kg. In contrast, the loads of the Air, Pro, X, and EDU versions of the Unitree G2 are approximately 7 kg (maximum 10 kg), 8 kg (maximum 10 kg), 8 kg (maximum 12 kg), and 8 kg (maximum 12 kg) respectively.

In the following animated image, an adult male weighing 105 kg stands on the body of the Unitree As2, far exceeding its marked standing load weight.

In the video, Unitree also mentioned that the Unitree As2 can be optionally equipped with accessories such as a 7 - axis dexterous robotic arm, which is expected to enable it to perform more diverse application functions.

Conclusion: Unitree's Quadruped Robots Make Further Efforts to Fill the Gap in the Lightweight Industrial - Grade Market

This is the first time that Unitree has released a quadruped robot since it launched the industry - grade quadruped robot Unitree A2 in August 2025, after a half - year interval. The last time it released such a "compact" quadruped robot dates back to July 2023 when it launched the consumer - grade product Go2.

The release of the Unitree As2 may fill the market gap between consumer - grade and industrial - grade products for Unitree Technology, forming a more segmented and complete product lineup of consumer - grade (Go series) - lightweight industry - grade (As2) - heavy - duty industry - grade (A2) - industrial - grade (B series).

With its small size, strong performance, and open ecosystem, the Unitree As2 is expected to enter scenarios such as inspection, scientific research, education, and light - duty operations with its lightweight and cost - effective features. We will continue to pay attention to the market's actual response to the As2 after its price and more parameters are announced.
