Researchers have developed CLUE (Closed-Loop contextual Uncertainty rEsolution), a framework designed to help robots actively resolve contextual uncertainty when faced with underspecified natural language tasks. CLUE utilizes a large language model to hypothesize concepts and plans, which are then grounded into actions using an online-constructed language-embedded map. The system iteratively refines its plans through environment interaction, demonstrating a success rate close to an oracle policy and significantly outperforming planners without closed-loop feedback. Experiments show that CLUE is more effective than simply querying a language-enriched map, achieving a higher success rate with fewer VLM tokens. AI
