AR-guided Product Disassembly for Maintenance and Remanufacturing

Product disassembly is an inevitable operation during the two essential modules in realizing a sustainable product life cycle: routine maintenance and end-of-life strategies particularly remanufacturing. In this paper, an AR-guided product disassembly (ARDIS) framework with an automatic content generation module is proposed to improve the efficiency of the disassembly process performed by human operator without expert intervention. Through intuitive AR-guidance in disassembling a product, the quality of maintenance services and effective core-retrieval during remanufacturing can be improved. A disassembly sequence table is first generated based on product ontology. Next, an automatic content generation domain will link the generated sequence with appropriate virtual information based on the taxonomy of visual cues. The final virtual content rendered on the real scene serves as straightforward step-by-step guide to the human operator. A case study of Nespresso machine is presented to demonstrate the preliminary workflow of the proposed framework.
