CASANDRA
(EXP – 00169779 / MIG-20242031)
Europe leads the manufacturing of complex and large-scale components. In Spain, the metal-mechanical sector is also booming, with significant growth (>8%) in recent years. This privileged competitive position is supported by the quality of manufactured products, their characteristics, high level of customization, efficiency, and lifecycle-related services. However, compliance with increasingly demanding regulations, high quality requirements, and product complexity are pushing existing technologies to their limits, threatening the sector’s competitiveness and its current privileged position. CASANDRA was created to address these challenges.
The main objective of the CASANDRA project is to develop a closed-loop digital manufacturing methodology that enables the concepts of a connected, intelligent, and autonomous factory, allowing the evolution of the digital twin of the component to be recorded throughout its lifecycle. This requires distributed monitoring and control tools, following a distributed data space model.
At the factory level, CASANDRA proposes the development of flexible, ubiquitous, and connected digital tools (collaborative robotics, AR/VR, and exoskeletons), designed to extend operators’ capabilities and increase efficiency, quality, and precision in the execution of required manufacturing processes.
Monitoring and control tools, together with transversal digital tools, open the door to the implementation of data analysis strategies that allow the collected data to be exploited. This enables CASANDRA to implement an autonomous factory concept through a decision-support system in which, based on collected live data, strategies are developed to adjust processes and continuously adapt to changing conditions and degradation of physical models. This involves working on edge intelligence, federated learning, and frugal AI by combining active learning and XAI.
After the completion of the first year of the project, the following conclusions can be established:
- Detailed requirements and specifications for the use cases have been defined

- A service-oriented digital architecture has been proposed to exchange data smoothly, interoperably, and reliably throughout the lifecycle, evolving towards a cloud-edge orchestration model capable of supporting a continuous Digital Thread between the plant and the cloud.
- After analyzing the functional requirements of the defined use cases, it was determined that the data security and integrity technologies currently implemented robustly meet the levels of trust required by the platform. The modular architecture of CASANDRA already guarantees traceability and immutability of records through highly efficient encryption and internal audit protocols, so the use of Blockchain infrastructure is not considered strictly necessary at this operational stage.
- The foundations have been laid for the generation of the product digital thread. Progress has been made in analyzing the practical relationship between CAD enriched with PMI, QIF for the definition of inspection features and tolerances, and their integration as the single reference product model. Likewise, the evaluation of AutomationML as a neutral exchange format and its linkage with AAS for structuring the product digital twin has begun. In parallel, the integration of OPC UA and AAS has been addressed as a key interoperability line.
- In order to develop tools and mathematical and physical models that allow the evaluation and prediction of the future behavior of manufacturing processes, finite element models for simple bending have been defined using ANSYS, and for the cladding process, initially in LS-Dyna and finally in ANSYS.
- User scenarios and worker task sequences have been defined in order to develop user-centered tools. In this regard, IDESA aims to redesign tasks adapted to real working conditions, considering both physical and cognitive ergonomics. NODOSA, on the other hand, aims to monitor confined spaces and exoskeletons, where operator fatigue can be monitored.
- In relation to the above, different types of sensors to be used to assess operator effort, stress, and fatigue levels, as well as the ergonomics of the activities performed, have been evaluated. In this sense, the use of different types of sensors has been proposed (IMUs, EMG, heart rate sensors, depth cameras, or textile sensors).
- For the specific plasma cutting scenario and the development of the user experience, a module for the quality control application has been designed and developed, including an adaptive graphical interface developed for sending images from a mobile device.
- An initial approach to solutions based on AR/VR technologies has been addressed to leverage operator monitoring information to improve safety in confined spaces through alert systems in critical situations, and to reinforce occupational risk prevention training through immersive experiences aimed at correcting ergonomic postures.
- Application scenarios for robotic technologies in intralogistics and collaborative robotics have been defined.

- Application scenarios for solutions based on augmented reality tools have been defined (projection system for positioning external elements and monitoring critical operator situations and generating ergonomic support alerts) to assist operators in manufacturing, assembly, and repair operations.

- Different designs of passive upper-body and lumbar-support exoskeletons have been proposed to fit the activities performed by operators in the use cases defined by IDESA and NODOSA. The development and integration of a first prototype of a sensorized exoskeleton for data acquisition has begun.
- The development of the Asset Administration Shell (AAS) has started, with the aim of representing and managing the assets involved in the manufacturing of large components throughout their entire lifecycle. This is necessary for generating digital twins of products and processes.
- A benchmarking of Edge devices for distributed factory control has been carried out, selecting the NVIDIA Jetson AGX Orin Development Kit (64GB) platform as the most suitable for the CASANDRA project.
