The Moving Eye: Enhancing VLA Spatial Generalization via Hybrid Dynamic Data Collection

Jincheng Tang, Yilong Zhu, Zhengyuan Xie +2

Vision-Language-Action (VLA) models have shown remarkable promise in generalized robotic manipulation. However, their spatial generalization remains fragile. We argue that simply i…
