WAM-OPD: On-Policy Distillation for World Action Models

Liuhaichen Yang, Zhuang Jiang, Chenchao Sheng +1

World action models (WAMs) couple visual future prediction with robot action generation, but accelerated students can lose task capabilities during distillation and later encounter…

Guided Action Flow: Q-Guided Inference for Flow-Matching Vision-Language-Action Policies

Liuhaichen Yang, Zhuang Jiang, Chenchao Sheng +1

Deploying a pretrained flow-matching vision-language-action (VLA) policy on a particular robot and workspace often calls for task-specific adaptation, while full- policy fine-tunin…

SignVLA: Real-Time Sign Language-Guided Robotic Manipulation via Attention LSTM and Vision-Language-Action Models

Ningwei Bai, Xinyu Tan, Harry Gardner +6

Vision-Language-Action (VLA) models enable robots to execute manipulation tasks from natural-language instructions grounded in visual observations. However, existing VLA interfaces…

SignVLA: A Gloss-Free Vision-Language-Action Framework for Real-Time Sign Language-Guided Robotic Manipulation

Xinyu Tan, Ningwei Bai, Harry Gardener +6

We present, to our knowledge, the first sign language-driven Vision-Language-Action (VLA) framework for intuitive and inclusive human-robot interaction. Unlike conventional approac…
