Abstract

Once a technician detects and reports an equipment failure, diagnostic systems and methods herein automatically generate a diagnostic plan, detailing necessary parts, areas of interest, and actions to be taken. Using augmented reality (AR) indicators, a system guides the technician while a perception module analyzes their actions to recommend next steps. A planning component uses knowledge graph (KG) and LLM to create the diagnostic plan, without requiring extensive data labeling or model training. A tracking component enhances 3D detections by employing perception sensors and a 2D nested object detection model. A guiding component simplified processed for novice technicians by integrating 2D models and AR interactions to ensure efficient and accurate diagnostics.
