Point Cloud-Based Multi-Robot Collaborative Spray-Painting Trajectory Planning and Production Line Simulation for Automotive Body

This paper presents a point-cloud-driven framework for collaborative robotic spray painting of automotive bodies. The method reduces dependence on complete CAD models by extracting geometric constraints from unorganized scan data. A body-coordinate-constrained partitioning strategy assigns the vehicle surface to six pa...

VLA-ULAP: Interleaving Cloud VLA Calls with Ultra-Lightweight Local Action Prediction at the Edge

VLA-ULAP partitions inference across decision times, interleaving remote VLA calls with predictions from an Ultra-Lightweight Local Action Predictor (ULAP), a single ULAP that combines current views, proprioception, and executed action history to predict chunks in one pass and surpasses local acceleration alternatives.
