ChunkVLA-AM: Parallel Action Chunking for Vision-Language-Action Robot Control in Additive Manufacturing
This arXiv preprint describes ChunkVLA-AM, a deployment pipeline that adapts an OpenVLA-OFT vision-language-action model to a FAIRINO FR3 robot for additive-manufacturing post-print retrieval. The robot predicts and executes 8-step chunks of 7-D Cartesian actions in a cloud-edge loop and completed 39 of 42 physical pick-and-transfer trials, a 92.9% success rate. The work provides a concrete feasibility check for using VLA-based automation in a fixed manufacturing workcell.
