A compact system designed to avoid unnecessary hardware components.
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:
Our prototype combines production simulation, image acquisition, AI inference, and operator feedback in one integrated architecture.
A compact system designed to avoid unnecessary hardware components.
The AI inspection program is hosted on an NVIDIA edge-computing platform with integrated control circuits.
Motion and production sequences are controlled through a programmable logic controller.
Operators receive clear inspection feedback through a practical interface.
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:
Our project considers security at the facility, during transmission, and at the receiving endpoint.
A cellular connection can separate data transfer from the facility network and reduce exposure to internal cyber threats.
Password-protected 7z encryption with metadata protection is paired with HTTPS/TLS during cloud transfer.
A WireGuard VPN tunnel can hide transfer activity from the cellular provider and support firewall protection through a static endpoint.
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.
