AgiBot X1 2026: Free Open-Source Humanoid, Specs & Status
AgiBot X1: the free open-source humanoid design — 34 DOF, full specs, how it compares to the Unitree G1, and its 2026 status.

On this page
The AgiBot X1 fills a critical gap in the humanoid robot market: an open-source platform that is free to build yourself. While competitors like Unitree G1 offer more raw capability, the X1's open architecture makes it the preferred choice for researchers who need to modify everything from motor control to AI frameworks. It's not trying to compete with industrial humanoids — it's purpose-built for the people advancing the field.
AgiBot X1 Overview
AgiBot (), the Shanghai-based robotics company behind the popular A2 series, launched the X1 as their dedicated research platform. Unlike their commercial-focused robots, the X1 prioritizes hackability over polish — open-source software, accessible hardware documentation, and a modular design that invites modification.
The company's philosophy with X1 is clear: give researchers a capable bipedal platform they can actually afford and fully customize, rather than a locked-down black box. One honest caveat for 2026 readers: the X1 repositories have been dormant since around April 2025, and AgiBot's commercial energy has moved to paid products like the Lingxi X2 (from ¥98,000). The X1 remains downloadable and buildable, but treat it as a stable snapshot rather than an actively developed platform.
AgiBot X1 Price Analysis
There is no X1 price, because AgiBot does not sell it: the X1 is a free open-source design. AgiBot published the bill of materials, STEP files, assembly instructions and software on GitHub in October 2024, so the real cost is whatever your sourced components come to. A few third-party integrators offer assembled units on a quote/waitlist basis, but there is no official retail channel.
| Robot | Price | Open Source | Primary Use |
|---|---|---|---|
| AgiBot X1 | Free open design (build it yourself) | Most (some components excluded) | Research/Education |
| Unitree G1 | $13,500 | Partial (EDU) | Research/Consumer |
| Unitree H1 | $90,000* | SDK only | Research/Industrial |
| Fourier GR-1 | Quote-only (no official price)* | SDK/ROS | Healthcare |
*Reported pricing; not officially published by manufacturer
Value Assessment: For academic budgets, the X1 hits a sweet spot — capable enough for serious bipedal research, affordable enough for university labs to justify, and open enough that students can learn from every layer of the system.

Open-Source Architecture
The X1's defining feature is its fully open-source design. AgiBot provides:
- Hardware Documentation: CAD files, assembly guides, and component specifications
- Software Stack: Full source code for locomotion, perception, and control
- AimRT Framework: AgiBot's open-source robotics middleware
- AGIBOT World Dataset: Training data for embodied AI research
This openness matters for researchers who need to:
- Modify motor control algorithms without reverse-engineering
- Integrate custom sensors and perception systems
- Implement novel AI architectures directly on hardware
- Reproduce and extend published research
PowerFlow Servo Technology
The X1 uses AgiBot's proprietary PowerFlow servo actuators — the same technology deployed in their commercial robots. Key characteristics:
- High torque density for bipedal locomotion
- Integrated motor drivers
- Force feedback capability
- Modular replacement design
While the servos are proprietary hardware, the control interfaces are fully documented for custom development.
34 Degrees of Freedom
The X1's 34 DOF configuration provides:
- Legs: Full bipedal locomotion capability
- Arms: Dual manipulators with 0.5kg payload each
- Hands: Dexterous end effectors for research manipulation tasks
- Torso: Core articulation for balance and reaching
This sits between the Unitree G1's 23-43 DOF range and research platforms that sacrifice DOF for simplicity.
Sensor Suite
The X1 includes research-appropriate sensors:
- Cameras: RGB vision for perception and navigation
- LiDAR: 3D spatial mapping and obstacle detection
- Force Sensors: Contact detection for manipulation research
- IMU: Orientation and balance sensing
Researchers can add additional sensors through documented expansion interfaces.
Use Cases
Academic Research
The primary use case. Universities can use X1 for:
- Bipedal locomotion algorithm development
- Reinforcement learning for embodied AI
- Human-robot interaction studies
- Computer vision and perception research
Robotics Education
Engineering programs benefit from:
- Full-stack robotics curriculum support
- Hands-on bipedal control experience
- Open codebase for learning
- Affordable lab deployment
AI Development
For embodied AI researchers:
- Physical testbed for simulation-to-real transfer
- Integration with AGIBOT World Dataset
- Custom model deployment
- Multi-modal learning experiments
Prototyping
Startups and R&D teams can:
- Validate concepts before custom hardware investment
- Test manipulation strategies
- Develop applications on proven platform
Pros and Cons
Pros
- Fully open-source — hardware docs, software, and training data
- Accessible pricing — designed for academic budgets
- 34 DOF — research-grade articulation
- AimRT framework — modern robotics middleware
- Commercially available — ships now, not pre-order
- AgiBot ecosystem — shared components with A2 series
Cons
- Limited payload (0.5kg) — not for heavy manipulation
- Shorter stature (130cm) — not human-scale
- Research-focused — not production-ready for deployment
- 2-hour battery — limited untethered operation
- China-based support — timezone and language considerations
X1 vs Competitors
| Feature | AgiBot X1 | Unitree G1 | Unitree G1 EDU |
|---|---|---|---|
| Price | Free open design (build it yourself) | $13,500 | Quote-only (~$44,000+) |
| Height | 130 cm | 132 cm | 132 cm |
| Weight | 33 kg | 35 kg | 35 kg |
| DOF | 34 | 23 | 23-43 |
| Open Source | Most (some components excluded) | No | SDK + ROS2 |
| Payload | 0.5 kg | 2 kg | 3 kg |
| Best For | Research/Education | Consumer/Demo | Research |
Bottom line: If you need maximum openness for research, X1 wins. If you need more payload and don't care about source access, G1 offers better specs per dollar.
Final Verdict
The AgiBot X1 is the humanoid robot that researchers actually asked for: affordable, open, and capable enough to do real bipedal research. It won't win demo reels against flashier competitors, but it will let you modify every line of code and every control loop.
The X1 is right for you if:
- You're a university or research lab needing bipedal hardware
- Open-source access matters more than peak performance
- You want to contribute to or build on shared research infrastructure
Look elsewhere if:
- You need payload capacity over 1kg — consider Unitree G1
- You want human-scale height — consider Unitree H1
- You need production-ready deployment — consider commercial options
- Open source doesn't matter to your use case
AgiBot made a strategic choice with X1: build the platform the research community needs, not the one that gets the most YouTube views. For academics and AI researchers, that's exactly right.

Frequently asked questions
- How much does the AgiBot X1 cost?
- Nothing, from AgiBot: the X1 is a free open-source design, not a product. AgiBot published the full build package on GitHub in October 2024, so your cost is the components you source. Third-party integrators quote for assembled units; no official price exists.
- Is the AgiBot X1 truly open source?
- Mostly. AgiBot released the hardware documentation, training and inference code, and the AimRT framework, but launch coverage notes some critical components were excluded, and the repositories carry custom or missing licenses rather than a standard OSI license.
- Can the X1 run autonomously?
- Yes. The X1 includes onboard computing, LiDAR, and cameras for autonomous operation. Battery life is approximately 2 hours for untethered research.
- How does X1 compare to Unitree G1?
- X1 prioritizes openness over raw capability. G1 has higher payload (2kg vs 0.5kg) and more locomotion demos, but X1 provides full source access that G1 doesn't match outside the EDU tier.
- What software does the X1 run?
- The X1 uses AgiBot's open-source AimRT framework. It's compatible with ROS and supports Python and C++ development.
- Where can I buy an AgiBot X1?
- You don't buy it from AgiBot. Download the design and software from AgiBot's GitHub (published October 2024) and build it, or request an assembled unit from a third-party integrator, which is quote-based and often waitlisted.
