Unitree Go2 Review: Specs, Price and Versions of the 15 kg Quadruped Robot
Updated: 7 days ago
The Unitree Go2 is a quadruped robot that weighs about 15 kg and carries a 4D LiDAR, sold in Air, Pro and EDU versions from USD 1,600. This review covers its specifications, design, versions, uses and price.
Quick Verdict
The Go2 is the best-known low-cost robot dog. All versions share the same body, twelve joint motors and a LiDAR that sees all around the robot, and they differ in speed, computing, battery and access for developers. The Air at USD 1,600 is a consumer and teaching product. The Pro at USD 2,800 adds an 8-core processor, voice, 4G and following functions. The EDU at USD 4,500 adds a depth camera, force sensors in the feet, a larger battery and full development access, and is the version for research. Battery life is one to two hours on the Air and Pro.

Design and Build Quality
The Go2 is the size of a medium dog and weighs about 15 kg, light enough for one person to carry. The body combines aluminium alloy with engineering plastic. Its LiDAR is mounted at the front and covers a hemisphere around the robot, down to objects 5 cm away, which lets it avoid obstacles and move over uneven ground. The Pro and EDU climb steps of about 16 cm and slopes of 40 degrees. The maker notes that some functions require human operation or further development.
