Unitree's First Decade: A 2016-2026 Model Timeline

Wang Xingxing founded Unitree Robotics in Hangzhou on 26 August 2016. The starting premise was to bring quadruped robots, then reachable only by a handful of research labs, down to an accessible price. Ten years on, the portfolio spans quadrupeds, humanoids and embodied-AI platforms.

The timeline below follows the six eras in Unitree's official tenth-anniversary graphic: Prototype → First Generation → Product Segmentation → Industry Application → Product Expansion → Humanoid Robots. Models we carry link to their product pages; for discontinued models only the name, year and successor are given.

• XDog (2013-2016) — The prototype Wang Xingxing built before founding the company; the first application of Unitree's direct-drive joint approach.
• Laikago (2017) — The company's first public product, named after Laika, the first dog in space.
• Laikago Pro (2018) — An upgraded Laikago.
• AlienGo (2019) — A mid-class platform aimed at higher payload and endurance. Its successor today is the Unitree AS2; see our AlienGo successor page.
• A1 (2020) — A fast, lightweight research platform; the model that introduced Unitree to a generation of university labs.

All four are discontinued. If you operate one of these platforms, contact us about spare parts and successor models.

In this era Unitree split one robot into three lines by use class: consumer/research (Go), heavy industrial (B) and field (A).

• Go1 (2021) — The first mass-market model, known for its side-follow system. Succeeded by Go2; we cover both in the Go1 vs Go2 comparison.
• B1 (2021) — The first industrial-line member, built around ingress protection and payload.
• Go2 (2023) — The best-selling model of the series, with 4D LiDAR L2 and AI interaction. Sold today as Go2 and the wheeled Go2-W.
• B2 (2023) — Successor to the B1 for heavy industry and inspection: B2 and B2-W.
• A2 (2025) — A field- and patrol-oriented generation: A2 and A2-W.
• AS2 (2026) — The newest working quadruped: AS2 and AS2-W.

This branch turned general-purpose platforms into variants adapted to specific sites: Fire Control (2022) and Inspection (2022) carry firefighting and facility-inspection equipment on a quadruped body. In 2025-2026 the same approach moved to the humanoid side with G1-D (2025), R1-D (2026) and H2-D (2026), fixed-base dual-arm workstation configurations. From this line we carry G1-D and R1-D.

The components around the robot became a product line of their own: the Z1 (2021) robotic arm, PUMP (2022) and PUMP MAX (2024), the L1 & L2 (2023) LiDAR sensors, and GD01 (2026). These mount on quadruped and humanoid platforms to widen mission scope; the L2 LiDAR, for instance, is standard equipment on today's Go2.

Robotlar.org is the authorized Unitree Robotics distributor for Turkey. Currently available: in quadrupeds, Go2, Go2-W, B2, A2 and AS2; in humanoids, G1, R1, H2 and H2 Plus. Installation, training, a one-year warranty and service across 81 provinces are included.
