ApexNav: An Adaptive Exploration Strategy for Zero-Shot Object Navigation with Target-Centric Semantic Fusion

ICRA 2026poster

Navigating unknown environments to find a target object is a significant challenge. While semantic information is crucial for navigation, relying solely on it for decision-making may not always be efficient, especially in environments with weak semantic cues. Additionally, many methods are susceptib…
