## Summary

The author integrated the open-source vision-language navigation model LightNav-0 into the Microduck simulation (MuJoCo). The robot receives instructions such as "walk to the wooden door frame and stop," predicts a path from first-person frames, and executes it via MPC and the official ONNX gait policy.
