WIRobotics Begins Building a Physical AI Development Ecosystem: The First Technology Release Features the ALLEX Simulation Model
WIRobotics, a global robotics company co-led by YounBaek Lee and Yong-Jae Kim, has announced the launch of its technology disclosure roadmap aimed at establishing a Physical AI development ecosystem. As the first step, the company released the simulation model of its humanoid robot, ALLEX, along with validated Sim-to-Real (Simulation-to-Real) results. The model is available in MJCF format for MuJoCo, USD format for Isaac Sim, and URDF format for ROS, allowing researchers and developers to conduct robot control, learning, and synthetic data generation studies without requiring physical hardware.
Building an Open Physical AI Ecosystem
Physical AI, which enables robots to perceive, reason, and act in the physical world, is emerging as a next-generation core technology in the global robotics industry. WIRobotics aims to go beyond traditional robot development by creating an open ecosystem where external researchers and developers can actively participate. The newly released ALLEX simulation model focuses on minimizing the Sim-to-Real Gap by precisely reproducing the real robot’s high backdrivability and force transparency. This ensures that the behavior of the physical robot closely matches the ideal simulation model, enabling faster algorithm validation and increasing the potential for successful deployment on physical hardware.
Quote from Co-CEO Yong-Jae Kim
Yong-Jae Kim, Co-CEO of WIRobotics, commented, “In humanoid robot development, 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 added, “We plan to make the ALLEX research platform available later this year. By releasing the ALLEX simulation model, we hope more developers will begin ALLEX-based research even before the hardware becomes widely available. We will continue expanding a development ecosystem where research outcomes can ultimately be applied to real robots.”
About WIRobotics
Founded in 2021 by former Samsung Electronics robotics engineers, WIRobotics develops wearable robots and humanoid robots. Its wearable robot WIM series has earned CES Innovation Awards from 2024 through 2026, and the company has expanded into Europe, Japan, and China. In 2025, WIRobotics unveiled the ALLEX humanoid robot platform and has since advanced its Physical AI research. In 2026, it was selected for the Physical AI Fellowship, a global program led by NVIDIA and Amazon Web Services, and successfully completed a Series B funding round of approximately KRW 95 billion.
