An agentic system for robotic question-answering and navigation that stores visual embeddings with pose and time in a vector database, grounding retrieval in a spatial map to answer queries with navigation goals.

It retains over 97% of its performance on frontier base models and still preserves 67% on small open-source models, while achieving over 250× storage compression without accuracy loss and 10× greater retrieval efficiency compared to a naïve VLM.

We introduce a novel benchmark for assessing machine physical commonsense on various continuum bodies, encapsulating conceptual inference and dynamic reasoning.
