Wiring Matters: Injection Topology and Initialization of Affordance Heads in Vision-Language-Action Policies
Zijian An, Linhan Wang, Jiayan Wang +4
Dense affordance supervision is an appealing auxiliary signal for vision-language-action (VLA) policies, yet naively co-training an affordance head can severely damage instruction…
ROG-Grasp: Root-Oriented Geometry for Robotic Grasping and Placement
Zijian An, Augustus Sroka, Ran Yang +8
Orientation-aware manipulation is essential in post-harvest agricultural processing, where produce must be grasped and placed in consistent configurations. This paper presents ROG-…
VILAS: A VLA-Integrated Low-cost Architecture with Soft Grasping for Robotic Manipulation
Zijian An, Hadi Khezam, Bill Cai +5
We present VILAS, a fully low-cost, modular robotic manipulation platform designed to support end-to-end vision-language-action (VLA) policy learning and deployment on accessible h…
SeqVLA: Sequential Task Execution for Long-Horizon Manipulation with Completion-Aware Vision-Language-Action Model
Ran Yang, Zijian An, Lifeng ZHou +1
Long-horizon robotic manipulation tasks require executing multiple interdependent subtasks in strict sequence, where errors in detecting subtask completion can cascade into downstr…
CLAW: A Vision-Language-Action Framework for Weight-Aware Robotic Grasping
Zijian An, Ran Yang, Yiming Feng +1
Vision-language-action (VLA) models have recently emerged as a promising paradigm for robotic control, enabling end-to-end policies that ground natural language instructions into v…
