The Unitree lineup explained: every series, from A to H
Updated 2026-10 Β· RobotMarket editorial
Unitree names its robots so densely that even enthusiasts lose track. The good news: every product sits in a series (a letter), and each series has generations that replace one another. Once you understand the letters, the whole catalogue clicks into place.
The letters
Consumer robot dog. The Go1 (2021) made quadrupeds mainstream; the Go2 (2023) added 4D LiDAR and dropped the entry price. If you want a robot dog for fun or light development, this is the series.
Developer and research class. The A1 was Unitree's famous back-flipping research quadruped; the A2 and As2 are its larger, stronger descendants.
Industrial quadruped. IP-rated, high payload, long runtime. The B1 β B2 progression is Unitree's push into inspection and patrol.
The 2019 large-payload platform that predates the B-series, now a legacy entry.
Unitree's 2017 debut β the robot that proved a small team could undercut Boston Dynamics by 10Γ.
Low-cost humanoid. The R1 (2025) is the headliner: a real biped for under $5,000.
Compact consumer humanoid. The G1 (2024) packs 23 degrees of freedom and dexterous hands into a $13,500 package built to be hacked.
Full-size flagship humanoid. H1 β H2 is Unitree's fastest-moving lineage, and the H2 arrives at a third of the H1's price.

Full timeline β- 1 Unitree H1 $90,000
- 2 Unitree H2 $29,900
- 2 Unitree H2 Plus $100,000
The H-series is the clearest example of how fast this market moves. The H1 launched at $90,000; within a generation the H2 arrived at $29,900 with better dynamics β a 67% price cut in roughly eighteen months.
Which Unitree should you buy?
Just want a robot dog: the Go2. Want to build software: the R1 or G1, depending on whether you want a small biped or a full-size one. Inspection or patrol: the B2. Serious research: the H2.
