Risk-Aware Belief Control Barrier Functions over Random Finite Sets
Shaohang Han, Gang Chen, Yixi Cai +5
The paper proposes a risk‑aware belief control barrier function framework that ensures robot safety in dynamic, uncertain environments by modeling multi‑object state uncertainty wi…
OpenSGA: Efficient 3D Scene Graph Alignment in the Open World
Gang Chen, Sebastián Barbas Laina, Stefan Leutenegger +1
Scene graph alignment establishes object correspondences between two 3D scene graphs constructed from partially overlapping observations. This enables efficient scene understanding…
Building Explicit World Model for Zero-Shot Open-World Object Manipulation
Xiaotong Li, Gang Chen, Javier Alonso-Mora
Open-world object manipulation remains a fundamental challenge in robotics. While Vision-Language-Action (VLA) models have demonstrated promising results, they rely heavily on larg…
BEACON: Language-Conditioned Navigation Affordance Prediction under Occlusion
Xinyu Gao, Gang Chen, Javier Alonso-Mora
Language-conditioned local navigation requires a robot to infer a nearby traversable target location from its current observation and an open-vocabulary, relational instruction. Ex…
MobileOcc: A Human-Aware Semantic Occupancy Dataset for Mobile Robots
Junseo Kim, Guido Dumont, Xinyu Gao +3
Dense 3D semantic occupancy perception is critical for mobile robots operating in pedestrian-rich environments, yet it remains underexplored compared to its application in autonomo…
Pushing Through Clutter With Movability Awareness of Blocking Obstacles
Joris J. Weeda, Saray Bakker, Gang Chen +1
Navigation Among Movable Obstacles (NAMO) poses a challenge for traditional path-planning methods when obstacles block the path, requiring push actions to reach the goal. We propos…
