Lightwheel deploys NVIDIA GR00T N1.5 humanoid robots in Geely's live automotive factory using Isaac Sim simulation

Overview

Lightwheel built a simulation-first robotics platform on NVIDIA Isaac Sim, Isaac Lab, and NVIDIA Omniverse libraries to address data scarcity and the sim-to-real gap in physical AI development. For Geely, Lightwheel fine-tuned the NVIDIA Isaac GR00T N1.5 vision-language-action foundation model to the Unitree H1 humanoid robot's morphology using simulation-generated synthetic data and DexMimicGen data augmentation, then deployed it in Geely's live automotive factory where robots autonomously perform component transportation, precise part placement on inspection trays, and coordinated dual-arm manipulation for heavy components. The platform achieves a 100:1 simulated-to-real data ratio and reduced development cycles from months to weeks.

The challenge

The embodied AI and robotics industry faces two fundamental barriers: data scarcity, since real-world data collection is slow and expensive, and the sim-to-real gap, where AI policies trained in simulation environments fail to translate to reliable performance on physical hardware — challenges that create substantial operational limitations for robotics researchers and developers deploying autonomous systems in manufacturing and other industries.

The solution

Lightwheel built the Lightwheel Simulation Platform on NVIDIA Isaac Sim, Isaac Lab, and NVIDIA Omniverse libraries. For Geely, Lightwheel fine-tuned the NVIDIA Isaac GR00T N1.5 vision-language-action foundation model to the Unitree H1 humanoid robot's morphology using simulation-generated synthetic data, teleoperation data collected via VR headsets and other devices, and DexMimicGen data augmentation across varied lighting, materials, and object placements, then deployed it in Geely's live automotive factory, where the robots autonomously perform component transportation, precise part placement on inspection trays, and coordinated dual-arm manipulation for heavy components.

Reported business value

The platform achieved a 100:1 simulated-to-real data ratio, eliminating expensive real-world data collection while maintaining physical accuracy, and reduced development cycles from months to weeks. Lightwheel successfully deployed GR00T N1.5-powered Unitree H1 humanoid robots in Geely's live automotive factory, autonomously performing tasks while maintaining balance in dynamic environments alongside human workers.
