HomeHelper - AI Agents for Appliance Troubleshooting

Co-developed multi-agent system using LangChain/LangGraph and SIM-RAG for appliance repair support. Integrated Llama-3 for orchestration, BLIP for vision analysis, and a Flan-T5 critic trained on iFixit synthetic data. The system provides intelligent troubleshooting guidance by combining visual understanding with textual repair manuals. Evaluated on MyFixit dataset and synthetic multi-turn dialogues to assess repair recommendation quality and user interaction effectiveness.
