Researchers have developed an AI system that guides workers in assembly and disassembly tasks using a combination of video recordings and narration from experts. The system extracts structured task knowledge from these recordings, enabling procedural documentation and context-aware worker guidance. This approach is evaluated on a real-world disassembly case study, showing improved results compared to traditional image-based methods. --- Why it matters: This work matters for engineers working in assembly and disassembly tasks because it provides a more accurate and efficient way of documenting and transferring expert knowledge. The system's ability to capture procedural structure and execution context can improve worker productivity and reduce errors. Source: https://arxiv.org/abs/2608.22617
