When Low Prediction Error Misleads Planning: Diagnosing Representation, Dynamics, and Decision Failures in Latent World Models
Rui Min, Xianyao Li, Fang Xu +1
The component that dominates a latent world model's prediction error need not be the one whose repair most improves action selection. We show this by comparing action sequences fro…
Nudge Before You Push: Physics-Aware Navigation via Tactile Probing
Xianyao Li, Fang Xu, Ruitong Tian +4
Visually identical containers can conceal loads that require different handling decisions. We present TANav, which uses a brief nudge to measure push resistance for navigation unde…
Minimal Recurrent Behavioral Memory for Imitation under Partial Observability
Xianyao Li, Fang Xu, Rui Min +2
What is the least recurrent memory needed to reproduce a specified expert under partial observability? The instantaneous requirement is the conditional entropy of the expert's beha…
Same World, Different Knowledge: When Isolated Audits Misjudge World-Model Repairs
Rui Min, Xianyao Li, Fang Xu +2
A repair favored under an isolated input fault can be inferior when deployed modules share the faulty information. We introduce an information-interface audit for world models, dis…
DreamLedger: Where to Refuse World-Model Imagination Using Execution-Settled Credit
Xianyao Li, Ruitong Tian, Rui Min +2
World-model predictions inform robot actions, yet instantaneous reliability signals do not retain the outcomes of comparable past predictions. DreamLedger registers consumed predic…
A 3DGS-Driven Dynamic Viewpoint and Vibrotactile Framework for Subsea Teleoperation Validated via fNIRS
Fang Xu, Tianyu Zhou, Ruitong Tian +2
Teleoperating remotely operated vehicles (ROVs) in flooded, cluttered infrastructure is fundamentally limited by narrow 2D egocentric views and subsea communication latency. We pre…
TEGA: A Tactile-Enhanced Grasping Assistant for Assistive Robotics via Sensor Fusion and Closed-Loop Haptic Feedback
Hengxu You, Tianyu Zhou, Fang Xu +2
Recent advances in teleoperation have enabled sophisticated manipulation of dexterous robotic hands, with most systems concentrating on guiding finger positions to achieve desired…
Augmented Reality for Maintenance Tasks with ChatGPT for Automated Text-to-Action
Fang Xu, Tri Nguyen, Jing Du
Advancements in sensor technology, artificial intelligence (AI), and augmented reality (AR) have unlocked opportunities across various domains. AR and large language models like GP…
