Untree AS2
The Unitree AS2 is a lightweight industry grade quadruped robot launched in February 2026, packing 90 newton meter joints, speeds above 5 meters per second and a 65 kilogram standing load into an 18 kilogram body, with a 648 watt hour battery covering more than 13 kilometers under a 15 kilogram payload, LiDAR perception, ISS 3.0 following and Jetson Orin NX development support.
Unitree AS2
Industrial robot dogs had settled into an unspoken rule: serious capability starts at 40 kilograms. On February 24, 2026, Unitree broke it with the Unitree AS2, a quadruped that weighs 18 kilograms with its battery, roughly a mid sized dog, and delivers approximately twice the dynamic performance of the consumer Go2: 90 newton meter peak joints, running speeds above 5 meters per second, a rated standing load of 65 kilograms, demonstrated in tests carrying a 105 kilogram adult, and more than 13 kilometers of walking range under a 15 kilogram working payload, the credentials of an industrial machine in a body one person carries to the site.
Unitree positions the AS2 as "lightweight industry grade," the tier the lineup previously lacked: above the Go2's consumer and research world, below the heavy A2 and extreme environment B2, for the inspection rounds, patrols and site work that need professional endurance and weather tolerance without a 40 kilogram logistics problem. Launch demonstrations made the argument physically, the AS2 crossing ditches, snowfields, jungle floor and rocky paths in harsh weather, and the market read it as the moment lightweight quadrupeds went to work.
Available in Pro and Edu configurations, with the wheeled AS2-W extending the platform, the Unitree AS2 for sale, with full specifications, can be explored through this page.
Background
The niche Unitree left open, then filled
By early 2026, the company's dog line bracketed the market without covering its middle: the Go2 owned consumer and laboratory territory at 15 kilograms and 45 newton meters, while the A2 and B2 served heavy industry from 42 kilograms upward. Professional users in between, inspectors, patrol operators, field crews, faced a choice between a consumer machine stretched past its rating and an industrial one heavier than the job. The AS2 is the answer engineered for exactly that gap: double the Go2's power in barely more mass, with the weather rating, endurance and payload arithmetic of a working tool, the launch that, in the market's phrase, completed Unitree's product line layout.
Strength the demonstrations made literal
The AS2's launch proof was cheerfully physical: a robot the size of a beagle carrying a 105 kilogram adult standing on its back, sprinting past 5 meters per second, keeping pace with a running human or a city e-bike, and walking verification routes through snow, rock and storm conditions, the twice the Go2 claim shown rather than told.

How does the AS2 compare to the Go2 and A2?
The three dogs now form a clean professional ladder. Against the Go2, the AS2 doubles the dynamics, 90 versus 45 newton meters, adds three kilograms, and converts a brilliant consumer and research machine's category into a rated working one: real payload, real range, a minus 20 to 50 Celsius envelope. Against the A2, whose 25 kilogram continuous and 100 kilogram static loads, dual industrial LiDAR and hot swap dual batteries serve the heaviest daily rounds, the AS2 trades top end payload for portability that changes deployment itself, one operator, one case, any site, at a fraction of the logistics. The rule of thumb: Go2 to learn and research, AS2 to work light and move fast, A2 and B2 when the payload or the environment is the mission.
Technology
Power density as the product
The AS2's engineering headline is its ratio: 90 newton meters of joint torque per 18 kilograms of robot, power density that buys the 5 meter per second sprints, 40 degree slopes, 25 centimeter steps and freight class standing loads, delivered through Unitree's self developed joint modules with local air cooling holding performance through sustained work.
Endurance built for routes, not demos
The 648 watt hour battery runs more than four hours unloaded and beyond two and a half under a 15 kilogram payload, translating to over 13 kilometers of loaded walking range, numbers stated the way operators plan, in route lengths, and sized so that a patrol circuit or inspection round completes on one charge.
An embodied mind with ISS 3.0
The AS2 ships with Unitree's bionic embodied large model for navigation and interaction and the upgraded ISS 3.0 Intelligent Following System, centimeter level positioning holding fluid side follow behavior, the robot as a self managing field companion that tracks its operator, while LiDAR, the HD camera and front lighting carry autonomous navigation and low light work.
Open where professionals need it
Pro and Edu configurations support secondary development on NVIDIA Jetson Orin NX computing atop the 8 core platform CPU, connecting the AS2 to Unitree's SDK ecosystem and support infrastructure, and to cross brand mission software, patrol and inspection systems like RoboPatrol and RoboInspect in the robot software catalog, that turns the platform into a working rounds machine.
What is the Unitree AS2 used for?
- Industrial inspection: checkpoint rounds across inspection robotics at sites where a 40 kilogram machine was always overkill.
- Security patrol: perimeter and facility circuits across security robotics, 13 kilometer legs on one battery.
- Site logistics and carry: 15 kilogram working loads following crews across logistics and industrial ground, ISS 3.0 keeping station at the operator's side.
- Emergency response: rapid deploy reconnaissance across emergency response robotics, one person portable to wherever the truck stops.
- Research and education: Edu trim development on Orin NX across research and educational programs, industrial dynamics at laboratory scale.
- All weather field work: the minus 20 to 50 Celsius, IP54 envelope carrying missions through the conditions launch demonstrations crossed, within the wider quadruped category.

Frequently Asked Questions
What is the Unitree AS2?
The AS2 is Unitree's lightweight industry grade quadruped, launched February 24, 2026: an 18 kilogram robot dog with 90 newton meter peak joints, speeds above 5 meters per second, a 65 kilogram standing load, roughly 15 kilogram walking payloads with over 13 kilometers of range and an IP54, minus 20 to 50 Celsius working envelope, offered in Pro and Edu trims with a wheeled AS2-W variant.
How does the Unitree AS2 work?
The AS2 moves on Unitree's high torque density joint modules under learning trained gaits, perceives through LiDAR and an HD camera with front lighting, navigates autonomously or follows its operator by the centimeter accurate ISS 3.0 system, runs a bionic embodied large model on its 8 core CPU and opens to secondary development through NVIDIA Jetson Orin NX computing.
Why is the Unitree AS2 important?
It ended the assumption that industrial quadrupeds start at 40 kilograms: professional payload, endurance and weather ratings in a machine one person carries, roughly doubling the Go2's performance in barely more mass, the launch that filled the last gap in Unitree's dog line and moved lightweight quadrupeds from demonstration to deployment.
What are the benefits of the Unitree AS2?
Key benefits include industrial capability at one person portability, 90 newton meter power density with 5 meter per second speed, route grade endurance beyond 13 loaded kilometers, a genuine all weather envelope, ISS 3.0 operator following, open Orin NX development and the ecosystem and pricing of the quadruped market's volume leader.
How much weight can the AS2 carry?
The AS2 is rated for standing loads up to 65 kilograms, and launch testing demonstrated it supporting a 105 kilogram adult standing on its back, while continuous walking work is specified around 15 kilograms of payload, at which it still covers more than 13 kilometers per charge.
What is the difference between the AS2 and the AS2-W?
Wheels: the AS2-W adds a leg wheel hybrid configuration at roughly 25 kilograms and 16 degrees of freedom, with peak torque near 95 newton meters and speeds around 6 meters per second, rolling where ground allows and stepping where it does not, the variant for missions that mix distance with terrain.
Where can I buy the Unitree AS2 and what does it cost?
The AS2 is for sale through Robots International, serving markets worldwide with delivery, customs clearance and support. Because cost varies by trim and options, buyers should request a tailored quotation. Full purchasing details are available on this page.
Summary
The Unitree AS2 is the industrial robot dog that fits in one hand count of kilograms: eighteen of them, carrying ninety newton meter joints, freight class standing strength, eleven mile an hour speed and a battery that walks thirteen loaded kilometers, through snow, rock and storm, behind its operator or on its own routes, with an embodied model onboard and Orin NX development open beneath. The machine that broke the weight rule of working quadrupeds and completed Unitree's dog line now defines its own tier. As the founding reference of lightweight industry grade robotics, the Unitree AS2 stands as the definitive starting point for putting a carryable quadruped to work.
