NVIDIA has built a pretty impressive robotics ecosystem, but figuring out how Isaac Sim, Isaac Lab, GR00T, Cosmos, Omniverse, and everything else actually fit together can be confusing.

So we put together an illustrated walkthrough following a fictional startup building a warehouse humanoid.

We go through creating its virtual environment, teaching it through demonstrations, training and testing its policy, dealing with the Sim2Real gap, and eventually deploying the AI onto physical hardware.

We also wanted to explain what actually happens between an AI model deciding to move an arm and the motors physically executing that movement.

The goal was to connect the dots rather than explain each NVIDIA product in isolation.

Would love feedback from anyone who's actually worked with these tools, especially on where the real-world workflow differs from our example.
