Human Behavior-Informed Crash Scenario Generation with Real-World Crash Priors for Autonomous Vehicle Safety Evaluation

Mingxing Peng, Xusen Guo, Long Chen وآخرون · 2026

Reliable safety evaluation of autonomous vehicles (AVs) is essential to improving road safety, yet it depends critically on realistic simulation of rare crashes. Existing crash scenario generation methods can increase collision occurrence, but often fail to realistically reproduce how crashes evolve before impact or th …

Efficient Multi-Modal Planning with Reward-Guided Preference Optimization for Autonomous Driving

Chenglin Chen, Lujia Wang, Xinhu Zheng وآخرون · 2026

Safe and efficient trajectory planning is essential in autonomous driving. However, existing end-to-end approaches often fall short in both computational efficiency and safety guarantees. Methods based on imitation learning suffer from causal confusion, while rule-based scoring approaches often incur heavy computationa …

SLIP-VLA: Single-Step Latent Imagination for Policy Learning in Vision-Language-Action Models

Tianfu Li, Haoxuan Xu, Wenbo Chen وآخرون · 2026

Vision-Language-Action models are increasingly effective for robotic manipulation, yet most predict actions directly from current observations without explicitly modeling future scene evolution. Recent methods introduce future prediction to improve action generation, but dense future modeling often requires expensive i …

A Topological Representation with Object-Path Graphs for Open-Vocabulary Instance Navigation

Linwei Zheng, Daojie Peng, Bingtao Wang وآخرون · 2026

Vision-language navigation requires embodied agents to navigate environments using natural language instructions and visual observations. Existing approaches typically decompose navigation into sequential language-guided decisions or rely on online exploration without prior environmental knowledge. Scene graph represen …

EmoPose: Vision-Language Model Guided Emotion-Aware Gesture Generation for Humanoid Robots

Daojie Peng, Bingtao Wang, Fulong Ma وآخرون · 2026

Socially competent humanoid robots must communicate affect and intent through gesture as well as speech, yet open-ended interaction must become motion that is both expressive and executable on a specific body. This demands semantic flexibility for contextual social intent while preserving deterministic, embodiment-awar …

ForceRFT: Refining VLA Actions through Force-Guided Residual Reinforcement Learning

Yichen Wang, Chaoyang Zhang, Xuqi Su وآخرون · 2026

Force-conditioned vision-language-action (VLA) policies can respond to contact, but when trained solely on demonstrations, their recovery behavior may be limited by demonstration coverage, and they do not learn from deployment outcomes. Human corrective imitation provides additional recovery examples, but its objective …

GR2PO: Group Relative Return Policy Optimization for Continuous Robot Control

Pengqin Wang, Qiming Zhang, Shaojie Shen وآخرون · 2026

Actor-critic architecture has been widely used in continuous robot control. However, they rely on learning a value network, introducing additional computational overhead during training. Moreover, policy learning may also be affected by the approximation error of value estimation. Critic-free group relative policy opti …

Learning Reliable Parking Policies via Offline Reinforcement Learning with Quantized Action Representations

Parking is a routine yet safety-critical task for autonomous vehicles operating in urban environments. However, cluttered and weakly structured parking spaces, compounded by the interactive uncertainty from surrounding vehicles, hinder reliable maneuver generation. To address these challenges, we develop a waypoint-lev …

Function-Preserving Data Generation for Zero-Shot Real-to-Sim-to-Real Manipulation

Tianyi Xiang, Xupeng Xie, Jiahang Cao وآخرون · 2026

Robotic data generation is a promising paradigm for scaling robot learning without collecting large-scale real-world data. However, generating geometrically diverse yet physically valid data for contact-rich tasks remains challenging, especially when success depends on precise geometric interfaces. Standard shape augme …

From Gameplay to Policy: Towards Scalable Robot Data Collection via Gamified Robot-Free Interaction

Zheng Li, Liang Zhu, Junzhe Wang وآخرون · 2026

Learning generalizable robot manipulation policies requires large-scale and diverse interaction data, yet collecting real-world demonstrations remains costly and difficult to scale. Existing approaches to data collection are either dependent on specific robot hardware that limits crowdsourcing and transferability, or s …
