CoReLIN: Constraint-based Reasoning for Zero-shot Lifelong Interactive Navigation

arXiv:2602.20055v2 Announce Type: replace-cross Abstract: Robot navigation typically assumes an obstacle-free path exists between start and goal. In real environments, however, clutter may block all routes. We introduce Lifelong Interactive Navigation, where a mobile robot with manipulation capabilities must move objects to forge paths and complete sequential object-placement tasks. Because environment modifications persist, decisions impact future navigability and task difficulty. We propose CoReLIN, an LLM-driven constraint-based reasoning framework with active perception. CoReLIN reasons ov

Why this matters
Why now

Advances in large language models (LLMs) and robotic manipulation are converging, enabling more sophisticated and autonomous robotic reasoning in complex, unstructured environments.

Why it’s important

This development pushes the boundaries of robot autonomy beyond obstacle avoidance to active environment modification, crucial for practical applications in logistics, disaster response, and domestic services.

What changes

Robots equipped with CoReLIN can now dynamically alter their environment to complete tasks, rather than being limited by static paths, significantly expanding their operational capabilities.
