Describe the scope of work in detail. Please include a summary of key deliverables.

Scope of Work

The projects undertaken were part of an effort to enhance detection and quality control capabilities for bottles within our processes. The scope of work covered two key initiatives: replacing traditional sensors with AI-driven Computer Vision and developing an anti-fraud system based on bottle identity verification.

1. Replacement of Traditional Sensors with AI-Driven Computer Vision

Description:
This project aimed to modernize bottle detection at the crusher stage by replacing traditional sensors with a Computer Vision solution powered by Artificial Intelligence. The implemented system can reliably detect the presence or absence of bottles, even under challenging environmental conditions.

Key Deliverables:

    Inference Engine: A highly accurate AI model capable of detecting bottle presence or absence with robust performance.
    Integration Code: Software enabling the deployment of the inference engine and secure transmission of collected data through an internal communication channel for processing and visualization.

2. Anti-Fraud System for Bottle Verification

Description:
The anti-fraud system was designed to create a "digital identity" for bottles entering our reception area. This process ensures that incoming bottles conform to expected specifications, significantly reducing risks related to fraud or discrepancies.

Key Deliverables:

    Inference Engine: An AI model capable of analyzing bottle characteristics (e.g., shape, content) and matching them against predefined expectations.
    Operational Software: A suite of tools leveraging inference results to identify anomalies or non-compliance.
    Hardware Selection and Integration: The Jetson Orin Nano platform was chosen as the hardware backbone for this project, following a comprehensive benchmarking process conducted in collaboration with Preste. This platform delivers high performance and seamless integration into the environment.

Summary of Key Deliverables

    Optimized AI models for presence/absence detection and bottle identity verification.
    Integration software for transmitting and processing information through internal communication channels.
    Jetson Orin Nano hardware platform, benchmarked and deployed to execute AI solutions effectively.

These efforts have significantly enhanced the reliability, precision, and traceability of our industrial processes while laying the foundation for future technological advancements.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

1. Sensor Replacement Project for BBots:

    The deployment is underway on our fleet of 900 BBots, demonstrating our strong confidence in the robustness of the implemented solution.
    Key measurable result: A significant reduction in breakdowns. While precise figures are still being consolidated, early feedback highlights a noticeable decrease in service interruptions, improving bbot availability and reliability.

2. Anti-fraud Project:

    We are currently in the phase of progressive deployment and solution fine-tuning.
    Early results are very promising, particularly in detecting anomalies related to the shape, color, and content of bottles.
    Key measurable result (preliminary): A reduction in manually detected fraud cases. We anticipate full adoption and significant efficiency gains in the coming months.

We connect experts, foster research collaboration, and support projects from proposal to implementation. With strong expertise in scientific communication, we bridge research and industrial innovation. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Preste?

We engaged Preste to address key challenges in research data management and the integration of artificial intelligence within our EU project NOVA. As research data management is becoming increasingly important in EU initiatives, we required a reliable expert partner. Additionally, we recognized the potential of machine learning and AI to enhance our project outcomes and sought Preste’s expertise to fully explore and leverage these technologies from the outset.

SOLUTION

What was the scope of their involvement?

Preste has been an integral partner in the NOVA project since the proposal development phase and continues to play a key role in its implementation (since September 2022). As the lead of a dedicated work package, the team has established and manages the project’s research data infrastructure, developing a comprehensive data management and analysis platform from the ground up within the first months of the project. Preste’s primary objective is to provide advanced data science support and develop in-silico predictive models that accelerate research across the consortium, particularly for scientific and academic partners. Their work enables the integration of experimental data with computational modelling to enhance understanding of coating performance and optimise development processes. Beyond modelling, Preste has contributed significantly to process automation, reducing manual workload for experimental teams. The team has developed tools such as automated colony counting for microbiologists and cell classification systems for biologists, improving efficiency and reproducibility. In addition to technical contributions, Preste actively supports the consortium’s dissemination and outreach activities.

What is the status of this engagement?

We started working with Preste in September 2022, and our engagement is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Our collaboration with Preste has had a measurable and transformative impact on the NOVA project. The research data management platform developed by Preste has become the backbone of our data operations, ensuring that all project data are Findable, Accessible, Interoperable, and Reusable (FAIR). The platform is now used by 100% of our consortium partners, who were fully trained by Preste to integrate it into their daily workflows. This has significantly improved data quality, traceability, and collaboration across all work packages. Preste’s automation tools have streamlined experimental processes, reducing manual workload and increasing accuracy. These tools are used daily by our research teams — for instance, automated colony counting for microbiologists and cell classification for biologists — enabling faster, more reliable data generation and analysis. Overall, Preste’s engagement has elevated the project’s scientific rigour, efficiency, and data-driven innovation, setting a new benchmark for collaborative research within the consortium. 

How did Preste perform from a project management standpoint?

Preste always delivers on time. We communicate via in-person meetings, virtual meetings, and email or messaging apps.

What did you find most impressive about them?

Preste has been a valuable partner from the very beginning. The team is consistently accessible, responsive, and highly adaptable in addressing any challenges that arise. Even when faced with risks or unforeseen issues, Preste engages proactively, ensuring that solutions are identified and implemented collaboratively and efficiently.

Are there any areas they could improve?

On-site meetings were sometimes difficult with the staff from Ukraine, but that was expected due to the current situation.
