The Lingxi X1 (also referred to simply as the AgiBot X1) is AgiBot's open-source, developer-focused humanoid robot. Where the A2 family targets industrial deployment, the Lingxi line is built for research labs, universities, and the maker community — a fully open-source platform designed to make full-size bipedal robotics genuinely affordable. It is one of the more notable open-source humanoids on the market, built around AgiBot's AimRT software framework.
Price Range
The Lingxi X1 is one of the most affordable full-size humanoid developer platforms available, with a developer kit reported at roughly $19,499 — under $20,000.

Model Breakdown
The Lingxi (X) series is AgiBot's open-source developer line, distinct from the industrial A2 family and the Genie series. It includes the X1, the wheeled X1-W, and the newer, more capable X2 (demonstrated riding scooters, hoverboards, and a self-driving bicycle). The X1 is the foundational open developer platform.
Buyer's Guide: What to Know
This is a research and maker platform — and it's cheap for what it is. At under $20,000 for a full-size, 34-DOF open-source biped, the Lingxi X1 is one of the lowest barriers to entry in humanoid robotics.
Open source is the core value. The AimRT framework and open design mean labs and developers can deeply customize locomotion, perception, and control — appropriate for teaching and research, less so for turnkey deployment.
It is compact, not heavy-duty. At 1.30 m and ~33 kg with ~0.5 kg-per-gripper lift, the X1 is built for learning and experimentation, not industrial payloads.
Consider the X2 for more capability. If your work needs more dynamic ability, AgiBot's newer Lingxi X2 is the step up; the X1 remains the affordable, foundational option.
Lingxi X1 vs Similar Robots
- Lingxi X1 vs Unitree G1: The two leading affordable compact research humanoids. The G1 starts a bit lower and has a very mature ecosystem; the Lingxi X1 counters with a fully open-source platform.
- Lingxi X1 vs Booster T1: Both are compact, developer-focused, sub-$20k-class robots; the X1 emphasizes open-source software, the T1 emphasizes athletic motion.
- Lingxi X1 vs EngineAI PM01: Both are affordable, ROS-friendly compact research humanoids aimed at universities and developers.
