SISREN – Spatial Intelligence and Structured Reasoning for Embodied Navigation | CoRL 2026

SISREN – Spatial Intelligence and Structured Reasoning for Embodied Navigation: Embodied navigation — the ability of autonomous agents to move purposefully through complex, unstructured environments — sits at the intersection of perception, cognition, and action. Despite significant progress driven by large-scale pretraining, state-of-the-art navigation systems still struggle with tasks that humans find straightforward: interpreting multi-step spatial instructions, reasoning about occluded regions, generalizing geometric priors across scene types, and composing spatial relations hierarchically. These gaps point to a fundamental challenge: current systems lack robust spatial intelligence — the capacity to form, manipulate, and exploit structured internal representations of the world for goal-directed locomotion. SISREN brings together researchers from robot learning, computer vision, cognitive science, and natural language processing to examine where spatial intelligence breaks down in embodied agents and how structured reasoning — for instance over maps, scene graphs, affordances, and language-grounded representations — can address these failures. The event is aimed at researchers and graduate students working on embodied navigation, scene understanding, and representation learning, especially relevant to the CoRL community's focus on deployable, generalizable robotic systems.
