New research questions LLMs' role in robot navigation, favoring geometry

A new research paper questions the extent to which large language models (LLMs) contribute to zero-shot gains in instruction-guided navigation systems. The study introduces two training-free variants, FPE and SHF, which rely on engineered geometric approaches and lightweight semantic heuristics respectively. Results indicate that careful geometric engineering can match or surpass LLM-driven performance, suggesting language models are more effective as heuristics than end-to-end planners in this domain.
