Step-by-step explanation of how to accomplish the **Vehicle Diagnostics Agent** project end-to-end:
## Vehicle Diagnostics Agent Project: Detailed Implementation Plan
### Phase 1: Project Setup and Planning
1. **Define Project Goals and Scope**
- Build a multi-agent AI system for predictive vehicle diagnostics.
- Agents will collaboratively analyze sensor data to detect anomalies, identify causes, recommend maintenance, and generate reports.
- Use realistic automotive sensor data (real/simulated).
- Demonstrate production-readiness with FastAPI backend and Gradio interface.
2. **Select Tools and Frameworks**
- LangChain and LangGraph for multi-agent orchestration.
- Python for logic implementation.
- PyTorch/TensorFlow for any ML model development.
- FastAPI for service endpoints.
- Gradio for user-friendly interface.
- Docker for containerization.
3. **Gather Data**
- Use open datasets like NASA Prognostics repository, Udacity self-driving car datasets, OR simulate vehicle telemetry in CARLA and inject anomalies.
### Phase 2: Data Collection and Preprocessing
1. **Acquire Vehicle Sensor Data**
- Collect time-series data such as engine temperature, speed, RPM, battery voltage, brake status, etc.
- For supervised learning, acquire or generate corresponding anomaly/fault labels.
2. **Clean and Process Data**
- Implement filtering to reduce noise (e.g., moving average, Kalman filtering).
- Normalize and synchronize sensor streams.
- Extract meaningful statistical and domain-specific features.
3. **Split Data**
- Partition into training, validation, and testing datasets.
### Phase 3: Build Individual Agents
1. **Data Ingestion Agent**
- Load or stream sensor data into the system.
- Prepare data for downstream agents.
2. **Anomaly Detection Agent**
- Train and deploy ML models (e.g., LSTM, CNN) to detect unusual sensor patterns.
- Use thresholding or probabilistic models for anomaly scoring.
3. **Root Cause Analysis Agent**
- Implement rule-based or ML models to infer possible causes of anomalies by correlating sensor data patterns.
- Integrate domain knowledge (e.g., engine fault codes mapping).
4. **Maintenance Recommendation Agent**
- Map root causes to actionable maintenance steps or alerts.
- Prioritize actions based on severity and impact.
5. **Report Generation Agent**
- Compile diagnostic summaries into clear reports for users/operators.
- Generate natural-language summaries.
### Phase 4: Agent Orchestration and Workflow
1. **Design Communication Protocol**
- Define how agents exchange information (inputs/outputs).
- Implement context/memory sharing to maintain state across steps.
2. **Implement Multi-Agent Orchestration**
- Use LangChain to manage sequential and parallel task execution among agents.
- Define orchestration logic to call agents in order (Data Ingestion → Anomaly Detection → Root Cause → Recommendation → Report).
3. **Add Error Handling and Recovery**
- Establish retry/fallback rules in case of agent failures or inconsistent data.
### Phase 5: Backend and Frontend Development
1. **FastAPI Service**
- Develop API endpoints for triggering diagnostics, retrieving reports, and health checks.
- Handle concurrent user requests.
2. **Gradio-based UI**
- Build an interactive dashboard for users to input vehicle IDs and view diagnostic reports.
- Visualize detected anomalies and recommended actions.
### Phase 6: Deployment and Monitoring
1. **Containerization**
- Create Docker images for backend and frontend.
- Use Docker Compose for service orchestration.
2. **Deployment**
- Deploy locally or on cloud (AWS, Azure).
- Configure environment variables and API keys securely.
3. **Observability**
- Add logging and monitoring for system performance and errors.
- Use LangSmith or other tracing tools to instrument agent workflows.
### Phase 7: Testing and Validation
1. **Unit Testing**
- Write tests for each agent’s logic.
- Validate correct anomaly detection and recommendations.
2. **Integration Testing**
- Verify multi-agent orchestration flows end-to-end.
- Simulate vehicle scenarios including anomalies.
3. **User Acceptance Testing**
- Gather feedback on Gradio interface usability and report clarity.
### Phase 8: Documentation and Presentation
1. **Write Comprehensive README**
- Explain project goals, architecture, how to run and extend.
- Include example data and system diagram.
2. **Prepare Demo and Presentation**
- Showcase live diagnostics on sample data.
- Highlight modular design and agent collaboration.
