A four-legged robot for $1,600

Go2 is a four-legged walking robot unveiled on 12 July 2023 by Unitree Robotics, founded in Hangzhou, China, in 2016. Unitree presented it as an embodied AI robot. The cheapest version, Go2 Air, cost $1,600 and the Go2 Pro $2,800; the EDU version for research and education was priced separately. It weighs about 15 kg and carries a LiDAR that sees in 360 degrees. The Pro understands voice commands through a GPT language model.

33,294 units in the IPO filings

Unitree has not disclosed sales of the Go2 alone. Figures released during its 2026 listing process on the Shanghai Stock Exchange’s STAR Market show that from 2023 to 2025 Unitree sold 33,294 quadruped robots and 5,632 humanoids across all models. Revenue grew from 159.13 million yuan in 2023 to 1.70 billion yuan in 2025. In September 2025 security researchers disclosed a flaw that let attackers take over Unitree robots, including the Go2, over Bluetooth. Unitree said that month that it had completed the majority of the fixes.

“Kind of a tool and kind of a toy”

A 2025 New Atlas review praised the Go2 Pro’s gait, stair modes and tricks. It also noted that the robot has to start on flat ground, its knees scratch easily, and it cannot patrol or inspect. Asked what the robot is for, the reviewer wrote: "The latter is a hard question to answer, as the bot is kind of a tool and kind of a toy." In October 2026 Unitree’s shop still sells the Go2 from $1,600, with some Pro configurations backordered.

Cheaper, and now the question is what it’s for

The Go2’s starting price is about 2% of Spot’s first sale price of $74,500. Spot sold at a high price to sites that had a clear job for it. The Go2 is cheap enough for individuals, but as the review pointed out, buyers have to decide what to use it for.

When a robot gets cheap, what jobs do people give it?
