AI-Based Manufacturing Solutions

Our interdisciplinary engineering research team is developing a low-cost, flexible, user-friendly, and secure solution to help manufacturing firms detect defects using artificial intelligence techniques.

Small and medium-sized manufacturers often face barriers, including affordability, that make traditional automation and inspection upgrades difficult to justify. The challenges include: 

  • Potential long downtime: System changes and equipment upgrades can interrupt production.
  • Reliance on experience: Inspection quality may depend heavily on individual worker expertise.
  • Expensive upgrades: Conventional inspection equipment can require major capital investment.
  • Data sensitivity: Manufacturers need practical AI solutions that protect proprietary information.

Our Approach: A Practical AI Inspection System

Our prototype combines production simulation, image acquisition, AI inference, and operator feedback in one integrated architecture.

  • Low-cost hardware

    A compact system designed to avoid unnecessary hardware components.

  • PyTorch-Based Inspection

    The AI inspection program is hosted on an NVIDIA edge-computing platform with integrated control circuits.

  • PLC-Controlled Simulation

    Motion and production sequences are controlled through a programmable logic controller.

  • User-Friendly HMI

    Operators receive clear inspection feedback through a practical interface.

Demonstration: Joint Cap Defect Detection

Our demonstration project applies computer vision by using convolutional neural networks (CNNs) to distinguish between acceptable and defective joint-cap conditions. 

A convolutional neural network is the kind of deep learning that makes self-driving cars possible or helps find abnormalities in medical scans. It begins with three-dimensional visual images and applies a convolutional layer of filters (called kernels) that detect edges and create a 3-D matrix that can be analyzed. Where other computations are algorithm-based, CNNs depend on pattern-based deep learning. Deep learning requires less computing power and data storage, which is why self-driving cars are possible without relying on supercomputers the size of a basketball court.

Our demonstration uses an open-source deep learning platform called PyTorch to inspect a joint cap. Here's how it works:

  • Image-based inspection: An AI model processes input images from the camera to classify the part’s condition.
  • Edge deployment: Inference is performed locally on the NVIDIA platform for fast response.
  • Preliminary results: The prototype demonstrates automated classification with a clear Helioseismic and Magnetic Imager (HMI) result.

Cybersecurity by Design: Protecting Manufacturing Data across the Workflow

Our project considers security at the facility, during transmission, and at the receiving endpoint.

 

On-site Protection

A cellular connection can separate data transfer from the facility network and reduce exposure to internal cyber threats.

Data in Transit

Password-protected 7z encryption with metadata protection is paired with HTTPS/TLS during cloud transfer.

End-site Protection

A WireGuard VPN tunnel can hide transfer activity from the cellular provider and support firewall protection through a static endpoint.

What Makes Our Approach Affordable and Reliable?

Zero-Trust Payload Isolation: Encrypting data directly on the local device ensures sensitive operational files are fully protected before leaving the local device.

Open Lightweight Encryption: AES-256 header encryption (-mhe=on) provides robust metadata protection without requiring proprietary software or paid platform licenses.

Encrypted Transit Channels: End-to-end transport is secured via standard HTTPS/TLS protocols integrated into modern cloud infrastructure. 

Flexible Network Architecture: Designed to support segmented cellular connections (SIM) or static IP endpoint tunnels for air-gapped facility safety.

Our In-Lab Test & Validation Plan

  • Payload Encryption: Compress sample inspection datasets into multi-part 7z archives using -mhe flags to verify complete filename and metadata masking.
  • Secure Cloud Offload: Transmit encrypted archives to cloud storage over HTTPS/TLS encrypted channels.
  • Transport Inspection: Inspect network payload traffic using protocol analyzers (Wireshark) to confirm full end-to-end transit protection.
  • Decrypt & Verify: Download archives to an isolated secondary endpoint and verify strict password enforcement prior to extraction.
