UniNav: A Unified World-Action Diffusion Model for Visual Navigation
Changqing Zhou, Yueru Luo, Zeyu Jiang +1
Image-goal visual navigation is a fundamental capability for embodied agents. Existing navigation policies efficiently predict waypoint trajectories but lack visual foresight, whil…
CRAG: Can 3D Generative Models Help 3D Assembly?
Zeyu Jiang, Sihang Li, Siqi Tan +8
Most existing 3D assembly methods treat the problem as pure pose estimation, rearranging observed parts via rigid transformations. In contrast, human assembly naturally couples str…
Monocular Open Vocabulary Occupancy Prediction for Indoor Scenes
Changqing Zhou, Yueru Luo, Han Zhang +2
Open-vocabulary 3D occupancy is vital for embodied agents, which need to understand complex indoor environments where semantic categories are abundant and evolve beyond fixed taxon…
FreeOcc: Training-Free Embodied Open-Vocabulary Occupancy Prediction
Zeyu Jiang, Changqing Zhou, Xingxing Zuo +1
Existing learning-based occupancy prediction methods rely on large-scale 3D annotations and generalize poorly across environments. We present FreeOcc, a training-free framework for…
LST-SLAM: A Stereo Thermal SLAM System for Kilometer-Scale Dynamic Environments
Zeyu Jiang, Kuan Xu, Changhao Chen
Thermal cameras offer strong potential for robot perception under challenging illumination and weather conditions. However, thermal Simultaneous Localization and Mapping (SLAM) rem…
GARF: Learning Generalizable 3D Reassembly for Real-World Fractures
Sihang Li, Zeyu Jiang, Grace Chen +9
3D reassembly is a challenging spatial intelligence task with broad applications across scientific domains. While large-scale synthetic datasets have fueled promising learning-base…
