SEES: A Self-Evolving Embodied System via Failure-Guided VLA Policy Adaptation

Ziwen Li, Hanlue Zhang, Zhenyang Ren +9

Recent vision-language-action (VLA) policies demonstrate promising generalization across diverse short-horizon tasks. However, they remain unreliable on long-horizon tasks, partly…

The Geometry of Flow-Matching Uncertainty: A Cost-free Uncertainty Proxy and Its Application in Flow-based VLA Failure Detection

Ziyang Rao, Yiren Zhao, Weiyu Guo +3

Flow matching (FM) has become a popular action head paradigm for modern embodied models. However, as a conditional generative model, it does not explicitly expose its inherent unce…

Suppression Sticks, Locality Is Fragile: A Closed-Loop Target-and-Control Audit of Task-Vector Negation in VLA Policies

Shaoguang Wang, Weiyu Guo, Rushi Dai +3

Task-vector arithmetic offers a closed-form way to modify a model, yet its behavioral locality remains unclear in closed-loop robot control. We present a target-and-control audit o…

How Should Vision-Language-Action Models Use Proprioceptive State?

Yiren Zhao, Ziyang Chen, Ziyang Rao +5

Recent Vision-Language-Action (VLA) models almost universally take robot proprioceptive state as input, yet wire it in incompatible ways -- serialized into text prompts, projected…

Source-Lifted Flow Matching for Intervenable Multimodal Imitation

He Zhang, Ying Sun, Pengteng Li +7

Flow-matching policies are promising for imitation learning because they model complex multimodal action distributions. However, their stochasticity is largely passive: repeated sa…

Spatial Memory for Out-of-Vision Manipulation in Vision-Language-Action

Pengteng Li, Weiyu Guo, He Zhang +4

We introduce SOMA, the Spatial Memory framework for Out-of-Vision Manipulation in Vision-Language-Action (VLA) models. Most existing VLAs implicitly assume that task-relevant objec…

Mirage2Matter: A Physically Grounded Gaussian World Model from Video

Zhengqing Gao, Ziwen Li, Xin Wang +12

The scalability of embodied intelligence is fundamentally constrained by the scarcity of real-world interaction data. While simulation platforms provide a promising alternative, ex…

NeuroVLA: A Brain-inspired Embodied Intelligence for Fluid and Fast Reflexive Robotics Control

Weiyu Guo, He Zhang, Pengteng Li +7

Vision-language-action (VLA) models inherit powerful semantic representations from large language models, but carrying over their design priorities can leave the demands of physica…

PosA-VLA: Enhancing Action Generation via Pose-Conditioned Anchor Attention

Ziwen Li, Xin Wang, Hanlue Zhang +8

The Vision-Language-Action (VLA) models have demonstrated remarkable performance on embodied tasks and shown promising potential for real-world applications. However, current VLAs…

SURPRISE3D: A Dataset for Spatial Understanding and Reasoning in Complex 3D Scenes

Jiaxin Huang, Ziwen Li, Hanlve Zhang +6

The integration of language and 3D perception is critical for embodied AI and robotic systems to perceive, understand, and interact with the physical world. Spatial reasoning, a ke…

MLLM-For3D: Adapting Multimodal Large Language Model for 3D Reasoning Segmentation

Jiaxin Huang, Runnan Chen, Ziwen Li +5

Reasoning segmentation aims to segment target objects in complex scenes based on human intent and spatial reasoning. While recent multimodal large language models (MLLMs) have demo…

UrbanGS: Semantic-Guided Gaussian Splatting for Urban Scene Reconstruction

Ziwen Li, Jiaxin Huang, Runnan Chen +5

Reconstructing urban scenes is challenging due to their complex geometries and the presence of potentially dynamic objects. 3D Gaussian Splatting (3DGS)-based methods have shown st…

Open-Vocabulary Segmentation with Unpaired Mask-Text Supervision

Zhaoqing Wang, Xiaobo Xia, Ziye Chen +4

Current state-of-the-art open-vocabulary segmentation methods typically rely on image-mask-text triplet annotations for supervision. However, acquiring such detailed annotations is…
