This research introduces Capability-Aware Traversability (CAT), a framework that embeds robot-specific physical constraints directly into spatial feature representations rather than relying on post-hoc filtering. By integrating these embodiment-aware vectors via SPADE blocks, the method significantly improves terrain classification metrics for both legged and wheeled platforms in unstructured environments. The approach represents a meaningful advancement in embodied AI navigation by ensuring safety predictions are intrinsically tied to platform morphology.
Towards Capability-Aware Traversability Navigation for Unstructured Environments
arXiv:2607.20679v1 Announce Type: new Abstract: Estimating traversability in unstructured environments requires conditioning on robot embodiment, as the same terrain can be traversable for one platform and unsafe for another. Existing methods often transfer predictions across morphologies through late-stage trajectory filtering rather than encoding platform constraints in the learned representation. We propose Capability-Aware Traversability (CAT), a framework that embeds physical limits directly into the spatial feature space. CAT grounds dense supervision masks in physical trajectories through an interactive annotation pipeline and modulates semantic terrain maps with robot-specific traversability vectors through Spatially-Adaptive Denormalization (SPADE) blocks. Across human-annotated and trajectory-aligned datasets, CAT leads all ranking-based metrics, improving AUROC by 11.0% on physically executed trajectories and AUPRC by 15.8% on human traces over the strongest baseline. Ablations show that spatial conditioning and per-robot prototypes produce capability sensitivity beyond generic path prediction. Deployments on a legged quadruped and a wheeled skid-steer demonstrate embodiment-aware obstacle avoidance on embedded hardware at 4.8 Hz.
