UniGround: Universal 3D Visual Grounding via Training-Free Scene Parsing
Jiaxi Zhang, Yunheng Wang, Wei Lu +8
3D Visual Grounding (3DVG) localizes objects from natural-language descriptions in 3D scenes and is fundamental to embodied AI applications. Although foundation models enable open-…
HERO: Hierarchical Traversable 3D Scene Graphs for Embodied Navigation Among Movable Obstacles
Yunheng Wang, Yixiao Feng, Yuetong Fang +5
3D Scene Graphs (3DSGs) constitute a powerful representation of the physical world, distinguished by their abilities to explicitly model the complex spatial, semantic, and function…
High-Precision Climbing Robot Localization Using Planar Array UWB/GPS/IMU/Barometer Integration
Shuning Zhang, Zhanchen Zhu, Xiangyu Chen +4
To address the need for high-precision localization of climbing robots in complex high-altitude environments, this paper proposes a multi-sensor fusion system that overcomes the li…
A Physics-Informed Neural Network Approach for UAV Path Planning in Dynamic Environments
Shuning Zhang
Unmanned aerial vehicles (UAVs) operating in dynamic wind fields must generate safe and energy-efficient trajectories under physical and environmental constraints. Traditional plan…
DreamNav: A Trajectory-Based Imaginative Framework for Zero-Shot Vision-and-Language Navigation
Yunheng Wang, Yuetong Fang, Taowen Wang +6
Vision-and-Language Navigation in Continuous Environments (VLN-CE), which links language instructions to perception and control in the real world, is a core capability of embodied…
