It reminded me of this work from NVIDIA Research - https://nvidia-ai-iot.github.io/remembr where they used VLMs and RAG on top of a real robot to navigate the Voyager campus in Santa Clara. You also might like the new OpenAI o3 models and how well they can play GeoGuessr ;)

Code is on NVIDIA's GitHub and is ~100 lines of Python.

I intend to post more frequently about applications of LLMs/GenAI in various domains, based on the work I am doing. Feedback on this post and suggestions on what I could write about are greatly appreciated!
