Key Takeaways
- WIRobotics has released the first element of its technology disclosure roadmap: a high‑fidelity simulation model of its humanoid robot ALLEX, together with Sim‑to‑Real validation results.
- The simulation reproduces the robot’s physical traits—especially high back‑drivability and force transparency—allowing researchers to develop control algorithms, AI models, and synthetic data without needing the hardware.
- Available in MJCF (MuJoCo), USD (Isaac Sim), and URDF (ROS) formats, the model aims to narrow the Sim‑to‑Real gap and foster an open Physical AI development ecosystem.
- WIRobotics plans to sequentially release additional core technologies from its humanoid robot program, expanding the ecosystem for external researchers and developers.
- The company, founded in 2021 by former Samsung Electronics robotics engineers, has earned CES Innovation Awards (2024‑2026), secured a KRW 95 billion Series B round (2026), and was selected for the NVIDIA/AWS Physical AI Fellowship (2026).
Announcement of the Technology Disclosure Roadmap
On June 28, 2026, WIRobotics unveiled its strategy to gradually open‑source the core technologies cultivated during its humanoid robot program. The initiative seeks to build an inclusive Physical AI development ecosystem where academic researchers, robotics engineers, and industry partners can experiment, validate, and innovate using the company’s tools. By sharing simulation models first, WIRobotics lowers the barrier to entry for algorithm development and synthetic data generation, setting the stage for broader collaboration before physical robots become widely available.
Release of the ALLEX Simulation Model
The inaugural release is the simulation model of WIRobotics’ humanoid robot ALLEX, accompanied by comprehensive Sim‑to‑Real validation data. The model is provided in three widely‑used formats—MJCF for MuJoCo, USD for NVIDIA Isaac Sim, and URDF for the Robot Operating System (ROS)—ensuring compatibility across major simulation platforms. This multi‑format approach enables developers to integrate ALLEX into their preferred workflows without additional conversion effort.
High‑Fidelity Sim‑to‑Real Validation
A central claim of the release is the model’s high fidelity: it accurately mirrors the real ALLEX’s physical characteristics, notably its high back‑drivability and force transparency. Validation experiments demonstrate that the robot’s behavior in the physical world closely matches that predicted by the simulation, indicating a minimal Sim‑to‑Real gap. Consequently, researchers can trust that control policies, learning algorithms, and synthetic datasets generated in simulation will transfer effectively to the actual hardware.
Benefits for Researchers and Developers
By providing a realistic virtual counterpart of ALLEX, WIRobotics empowers users to conduct robot control, reinforcement learning, imitation learning, and perception research without needing to procure or maintain a physical robot. This capability accelerates iteration cycles, reduces experimentation costs, and allows parallel exploration of multiple algorithms. Moreover, the ability to generate large volumes of annotated synthetic data in simulation supports training of deep‑learning models that would otherwise be prohibitively expensive to gather from real‑world trials.
Vision for an Open Physical AI Ecosystem
WIRobotics’ long‑term goal extends beyond a single simulation release. The company intends to progressively disclose additional core technologies—such as actuator models, sensor suites, perception pipelines, and control frameworks—developed throughout its humanoid robot program. Each release will enrich the open ecosystem, encouraging external contributions, benchmarking, and the creation of community‑driven tools that can ultimately be deployed on physical ALLEX units or derived platforms.
Supporting Materials and Outreach
Alongside the model release, WIRobotics published a technical demonstration video on its official YouTube channel. The video walks viewers through the Sim‑to‑Real validation process, showing side‑by‑side comparisons of the real ALLEX executing motions and its simulated counterpart reproducing the same trajectories. Visual evidence of alignment reinforces confidence in the model’s accuracy and serves as an educational resource for newcomers to simulation‑based robotics research.
Leadership Commentary
Co‑CEO Yong‑Ja Kim emphasized the strategic importance of simulation in humanoid robotics:
“Simulation models are a core infrastructure that serves as the foundation for learning, validation, and synthetic data generation. A simulation environment that effectively reflects the characteristics of the real robot enables developers to validate algorithms more quickly and increases the potential for successful deployment on physical hardware.”
He further noted that the ALLEX research platform will be made publicly available later in 2026, inviting developers to begin experimentation now and to transition seamlessly to hardware once it reaches broader distribution.
Company Background and Achievements
Founded in 2021 by a team of former Samsung Electronics robotics engineers, WIRobotics has rapidly ascended in the robotics sector. Its wearable‑robot WIM series garnered CES Innovation Awards for three consecutive years (2024‑2026), underscoring the firm’s technical prowess. In 2025, the company introduced the ALLEX humanoid robot platform, marking its entry into advanced humanoid research. The following year, WIRobotics was selected for the prestigious Physical AI Fellowship, a global initiative led by NVIDIA and Amazon Web Services that recognizes outstanding contributions to perception‑action‑loop technologies for robots.
Financial Milestones
To fuel its ambitious roadmap, WIRobotics closed a Series B funding round in 2026, raising approximately KRW 95 billion (≈ USD 70 million). The capital infusion is earmarked for accelerating next‑generation robotics technologies, expanding the company’s global footprint, and scaling the open development ecosystem it is now cultivating.
Access and Further Information
Interested parties can access the ALLEX simulation model and related documentation via WIRobotics’ official GitHub repository (https://github.com/wirobotics-rih/allex_model). Additional details, including the demonstration video and contact information, are available on the company’s website and YouTube channel (https://www.youtube.com/watch?v=5fsfo_FZDS0).
Through this staged disclosure, WIRobotics aims to democratize access to cutting‑edge humanoid robotics technology, spur innovation across academia and industry, and ultimately shorten the timeline from algorithmic breakthrough to real‑world robotic deployment.
