StrataVLA: Hierarchical and Efficient 3D Geometric Grounding for Vision-Language-Action Models

StrataVLA is introduced, a plug-and-play framework for hierarchical geometry grounding that achieves 98.53% average success on LIBERO suites while reducing geometry-model invocations by up to 88%, establishing hierarchical geometry injection as an effective and efficient way to achieve spatially grounded robotic contro...
