Unitree A2 Quadruped Robot

The Unitree A2 is the serious field quadruped — 25 kg of payload, hot-swap batteries for five-hour runs, an Intel i7 on board, 30 cm stairs and −20 °C operation, with a wheel-leg A2-W twin and a full line of thermal, gas and acoustic inspection kits.

Overview

What is the Unitree A2 Quadruped Robot?

The Unitree A2 sits between the compact Go2 and the industrial B2: about 37 kg with both batteries, 25 kg of continuous payload, 20 km on a charge, and an Intel Core i7 inside for your own software next to the 8-core platform CPU. The A2-W puts the same machine on wheel-legs for long patrols over pavement and plant floors.

Beyond the Standard and Pro builds, Unitree packages the A2 and A2-W as inspection robots: the INS-S1 adds a stabilised thermal and 25× zoom gimbal, the S2 a specialty gas module, the S3 acoustic leak imaging, and the S4 all three — each also available as a PRO with a 100 TOPS compute backpack. Prices below are current US list prices from our catalog; a RobotLAB specialist confirms configuration, lead time and financing before anything is ordered.

How it works

Unitree A2 Quadruped Robot in detail

Choosing a configuration

Start with the question of legs or wheel-legs, then whether you need the Pro's second LiDAR, GPS, 4G, expansion dock and autonomous navigation. Inspection customers pick the sensor set: thermal gimbal (S1), plus gas (S2), plus acoustic imaging (S3), or everything (S4), and add PRO when the analysis should run on the robot rather than in the cloud.

Configurations
