ESP-SLAM: Efficient Submap Partitioning for Large-Scale 3D Gaussian Splatting-Based SLAM

RA-L 2026

Recent SLAM systems have adopted 3D Gaussian Splatting (3DGS) to generate photorealistic maps. Despite its high fidelity, scaling 3DGS-SLAM to large scenes remains challenging. In most implementations, 3DGS maintains a single globally shared set of Gaussians, which can cause catastrophic forgetting

How to Relieve Distribution Shifts in Semantic Segmentation for Off-Road Environments

ICRA 2026poster

Semantic segmentation is crucial for autonomous navigation in off-road environments, enabling precise classification of surroundings to identify traversable regions. However, distinctive factors inherent to off-road conditions, such as source-target domain discrepancies and sensor corruption from ro…

PTS-Map: Probabilistic Terrain State Map for Uncertainty-Aware Traversability Mapping in Unstructured Environments

RA-L 2025

Traversability mapping for autonomous navigation in unstructured environments has been widely investigated for decades. However, it remains challenging due to the uncertainty in geometry perception and the simplified representation of traversability maps that fail to capture detailed structures of e

Adaptive Robot Traversability Estimation Based on Self-Supervised Online Continual Learning in Unstructured Environments

RA-L 2024

Traversability estimation is a core function for robot navigation in off-road unstructured environments and diverse research results have been published so far. One of the recent approaches is using the self-supervised learning (SSL) technique. SSL has been focused on as a breakthrough technique for
