Motor Control Center Visual Inspection with Google ADK and Modal

Manual quality inspection of custom Motor Control Centers (MCC) introduces long delivery lead times and assembly defect leakage. Build an automated visual defect inspection agent using Google ADK and Modal serverless GPU inference to classify MCC assembly defects with sub-500ms processing latency.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

defect_detected

Ensures that genuine assembly defect is flagged.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

mean_average_precision

mAP score for terminal block defect localization • target: 0.92 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Deploy Gemini Vision multimodal model on Modal serverless GPU workers

  • Utilize Google Agent Development Kit (ADK) to build interactive defect triage tools

  • Classify MCC wiring errors, missing terminal block snaps, and component misalignments

  • Generate structured inspection audit logs with spatial bounding coordinates
