GlassGuard: Verified Glass Plane Mapping for Robot Navigation

Transparent and specular surfaces pose a serious challenge to LiDAR-based SLAM and navigation because laser returns may pass through glass, leaving collision boundaries absent from the map. Prior work attempts to reconstruct the missing surfaces, but inaccurate obstacle placement can create the opposite failure: contam...

SuperMap: A Spatio-Temporal SLAM System for Visual-Language Navigation

This work presents SuperMap, a 4D spatio-temporal mapping framework for language-guided navigation that integrates high-frequency geometric SLAM with asynchronous open-vocabulary perception and releases the full system as open-source to provide the community with a deployable baseline for open-vocabulary spatio-tempora...
