State Department of Transportation – Mechanic Copilot
Hands-free retrieval of repair manuals and fleet documentation
- Mechanic Copilot application
- Document retrieval and knowledge base
- RAG solution design and implementation
- Document ingestion and parent‑child mapping
- Retrieval‑Augmented Generation (RAG)
- Voice control and speech-to-text
Project Overview
A retrieval system that surfaces repair manuals and documentation for fleet maintenance. It uses parent‑child document mapping to return precise, section‑level answers with full context, and voice control for hands‑free operation in the bay.
The Challange
- Mechanics need fast, accurate answers from lengthy, multi‑level manuals
- Documentation spans components and subcomponents, making section‑level retrieval difficult
- In‑bay, hands‑free access is required to keep technicians on task
Our Solution
We delivered a Mechanic Copilot that unifies repair manuals and fleet documentation behind a RAG engine. Parent‑child document mapping enables granular retrieval while preserving context from the source. A voice interface supports hands‑free search and step‑by‑step guidance at the vehicle.
Features:
- Parent‑child doc mapping for precise, contextual answers
- Voice‑first search and readout for hands‑free use
- Unified retrieval across manuals and fleet documentation
The Results
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse varius enim in eros elementum tristique. Duis cursus, mi quis viverra ornare, eros dolor interdum nulla, ut commodo diam libero vitae erat.
Faster case completion
Staff adoption in 2 weeks
Reduced task duplication
Annual cost saving through improved efficency
The Results
- Time to locate repair procedures: Not disclosed
- Accuracy of document retrieval: Not disclosed
- Hands‑free usage in bay: Enabled
- Content coverage: Repair manuals and fleet documentation
