Retrieval‑Grounded Robot Program Generation and Simulation‑Based Correction via Model Context Protocol
Retrieval‑Grounded Robot Program Generation and Simulation‑Based Correction via Model Context Protocol
Abstract: Flexible manufacturing demands rapid re‑programming of industrial robots as product variants evolve. A new language‑model‑driven workflow combines dual‑stream Retrieval‑Augmented Generation (RAG) with a Model Context Protocol (MCP) server to generate, validate, and iteratively correct ABB RAPID robot programs directly from natural‑language task descriptions. By grounding code generation in verified technical documentation and production templates, the approach dramatically reduces domain‑specific errors while providing a closed‑loop simulation feedback from ABB RobotStudio.

Key Contributions
- Dual‑Stream RAG Pipeline: Retrieves relevant technical documents and template code in parallel, ensuring generated programs are contextually accurate.
- Model Context Protocol (MCP): A lightweight server that streams generated code to ABB RobotStudio, runs simulations, and returns diagnostic feedback for automatic correction.
- Simulation‑Based Correction Loop: Detects execution failures (e.g., suction release‑height errors, unreachable placements) that static checks miss, enabling iterative refinement.
- Benchmark Results: A 30‑query retrieval benchmark shows a 42% reduction in code‑generation errors; real‑world RobotStudio case studies demonstrate successful pick‑and‑place operations.
Why It Matters for Industry 4.0
The integration of RAG and MCP bridges the gap between natural‑language intent and executable robot code, cutting down on expert setup time and minimizing costly production downtime. This workflow can be directly adopted in smart factories seeking to scale product customization without sacrificing reliability.
