RAVEN: Long-Horizon Reasoning & Navigation with a Visuo-Spatio-Temporal Memory
Researchers introduce RAVEN, an agentic memory system that enables robots to perform long-horizon navigation and question-answering tasks by storing visual embeddings with spatial-temporal metadata in a vector database. The system achieves 10× lower retrieval costs than caption-based approaches while matching frontier vision-language models, and has been successfully deployed on physical robots for real-world navigation.
