This paper presents the design, modeling, and comparative analysis of two Permanent Magnet Synchronous Motors (PMSMs): one featuring Yttrium Barium Copper Oxide (YBCO) high-temperature superconducting (HTS) windings in the stator, and the other a conventional copper- based design. The aim is to assess the potential benefits of superconducting technology for applications where weight and compactness are vital, like aerospace applications. Using Finite Element Method Magnetics (FEMM) and Lua scripting, key parameters such as torque, electromagnetic flux distribution, hysteresis losses, and resistive losses were analyzed. The YBCO-based motor exhibited significantly higher flux densities and torque values than its copper counterpart, highlighting clear performance advantages. However, the necessity of cryogenic cooling at 77 K introduces additional complexity, requiring careful consideration of overall system efficiency. Furthermore, variations in the critical current density (Jc) with magnetic field intensity and the risk of quenching when operating currents approach or exceed Jc underscore the importance of accurate thermal and electromagnetic modeling. These findings demonstrate the promise of HTS stators in PMSMs, while also emphasizing the need for integrated, multi-physics approaches to ensure reliable and efficient operation.
10:12am - 10:24amAffordable Robotics Solutions for STEM Outreach and Education in Electronics

This paper explores affordable robotics solutions designed to enhance STEM education in Ireland, focusing on both third-level undergraduate courses in electronics and electrical engineering, as well as STEM outreach for primary school children. As the demand for skilled STEM professionals grows, there is a pressing need to provide accessible, hands-on robotic learning experiences that bridge the gap between theory and practice. However, the high cost of traditional robotics platforms remains a significant barrier in this regard. To address this, the paper investigates cost-effective robotics solutions aimed at fostering engagement, practical skills, and problem-solving abilities in students at different educational levels. These include low-cost programmable robotics kits for third-level students to experiment with automation and circuit design as well as open-source robotics platforms that encourage customization and accessibility. Using these for interactive robotics workshops with primary school children to introduce fundamental electronics concepts, as well as collaborative robotics projects promotes teamwork and learning across age groups. The paper considers the effectiveness of these solutions in promoting STEM, assessing factors such as affordability, accessibility, and pedagogical impact. Ultimately, it provides a framework for integrating affordable robotics into educational settings, contributing to a more inclusive and sustainable approach to STEM education in Ireland and beyond.

This paper describes the design of an automatic pill dispenser, which is developed from a CAD model, which is then 3D printed. Subsequently, the device is assembled incorporating the necessary electronics for its operation, using an ESP32 microcontroller card. To facilitate the control of the dispenser, a mobile application is created using APP Designer, which allows to manage and activate the servomotors responsible for the dispensing of the tablets. The mobile application facilitates the user's interaction with the system, making it possible to program and control the dispensing of medication in a precise manner. In addition, the effectiveness of the module is validated when used through the mobile application, ensuring its correct functioning in the dispensing process. This design not only optimizes medication administration, but also incorporates safety measures to prevent accidents, especially in environments with children, providing additional control to prevent minors from having unauthorized access to medications. In this way, the system not only improves accuracy and efficiency in tablet dispensing, but also offers a level of protection, ensuring safe and proper use of the dispenser

The project develops an automated device for bending wires up to 2 mm in diameter, using low-cost technology. The machine combines mechanical and electronic design to ensure functionality and simplicity. On the mechanical side, the design was made with Autodesk Inventor, and the main parts, such as the bending shaft and smoothing rollers, were analyzed with ANSYS Workbench to validate their strength. These parts were manufactured using 3D printing with inexpensive filaments, to reduce costs. The structure allows for a bending shaft operating range of -110° to 110°, suitable for different bending configurations. On the electronic side, NEMA 17 motors, A4988 controllers and an ESP32 were integrated. The system uses a dual source of 5V, 12V and 3.3V. The user interface was developed with Blynk IoT, allowing intuitive remote control from mobile devices. During implementation, tests were carried out that ensured accuracy and repeatability, with a margin of error of ±2 mm and a maximum capacity of 50 mm per operation. The results demonstrated the feasibility of the design, identifying improvements such as the use of more resistant materials, additional sensors and a greater operating range. This project stands out for its focus on economic sustainability and technological accessibility, representing an innovative solution for bending processes in low-budget environments. Future proposals include expanding the system's capabilities, optimizing accuracy, and improving the durability of critical parts.
