Learn how to use LLMs for text-based exploration and navigation in unknown environments with partial observability

advanced Published 14 Apr 2026
Action Steps
  1. Build a text-based controller using LLMs to navigate in unknown layouts
  2. Configure the LLM to function under partial observability without code execution or program synthesis
  3. Test the LLM controller in a reproducible benchmark with oracle localization in fixed ASCII gridworlds
  4. Apply the LLM controller to real-world scenarios such as inspection, logistics, and search-and-rescue
  5. Compare the performance of the LLM controller with other navigation methods

Title: LLMs for Text-Based Exploration and Navigation Under Partial Observability

Abstract:
arXiv:2604.09604v1 Announce Type: new Abstract: Exploration and goal-directed navigation in unknown layouts are central to inspection, logistics, and search-and-rescue. We ask whether large language models (LLMs) can function as \emph{text-only} controllers under partial observability -- without code execution, tools, or program synthesis. We introduce a reproducible benchmark with oracle localisation in fixed ASCII gridworlds: each step reveals only a local $5\times5$ window around the agent an
