“…As a consequence of computational vision's importance not only in industry but supporting the day-to-day activities of a large part of society, a lot of effort has been focused on improving undergraduate student training to provide the specialized knowledge that technological companies require for the development of such sophisticated systems [3,16,20,40,46]. According to Hernandez-de-Menendez et al [21], there are nine technological advances that are currently supporting the so-called Industry 4.0: autonomous robots, simulation, horizontal and vertical system integration, industrial internet of things, cybersecurity, the cloud, additive manufacturing, augmented reality, and big data and analytics.…”

The field of computer vision is characterized by computationally intensive algorithms and techniques with strict real‐time requirements. Field programmable gate arrays (FPGAs) are based on a concurrent paradigm which allows the design of efficient hardware architectures and has positioned FPGAs as an ideal device for implementing compute‐intensive applications. For this reason, FPGA technology has had a great impact in areas such as computer vision, where one of the main objectives for researchers working in this field is to create efficient automatic object recognition systems. Therefore, the need to provide undergraduates with the necessary skills to design FPGA‐based object recognition systems is evident. With this aim in mind, it is essential that specialization courses related to the design of these systems include the required resources for the student to apply the theoretical knowledge in solving practical problems. In this article, we present a development tool designed to help students, teachers, and researchers during the design‐modeling‐implementation process of object recognition systems based on FPGAs. The proposed tool operates under a modular approach as this facilitates the working on any of the phases of a recognition system and it is considered as a hybrid because the other phases can be developed using a software language. An empirical evaluation involving undergraduates enrolled in a Computer Engineering program was conducted to create a hardware architecture for the DAISY descriptor that uses the homogeneous features of objects immersed in images to produce an efficient representation. By considering similar descriptors such as Scale‐Invariant Feature Transform (SIFT) and Histogram of Oriented Gradients (HOG), DAISY is computed by convolving orientation maps instead of using weighted sums of gradient norms, which offers the same kind of invariance at a lower computational cost for the dense case. The results obtained during such an evaluation indicated that students consider this FPGA‐based tool to be an alternative to receiving practical training on designing systems for solving problems related to the area of object recognition.

“…Education with the 4D Frame Mechatronics Kit is possible to realize at different levels of education. In Guerrero-Osuna, Nava-Pintor, Olvera-Olvera, Ibarra-Pérez, Carrasco-Navarro and Luque-Vega (2023) [55], referring to engineering education in the bachelor stage of study, showed how it is possible to implement Seymour Papert's constructionism [34] and technology integration in education. Additionally, in our case, the students-future teachers for primary education according to the mentioned study in the following presented activities-actively constructed their knowledge from their experiences and interactions with the environment and set 4D Frame Mechatronics Kit.…”

Education is a constantly evolving field that encompasses various approaches to teaching and learning. In our paper, we focused on qualitative research conducted with future primary level teachers using a STEAM (Science, Technology, Engineering, Arts and Mathematics) approach. The research involved classroom observation, analysis of the student work, and obtaining interpretations from the students via report protocols and focused interviews. We examined the students’ learning and problem-solving strategies within STEAM-based activities as well as their perspectives on its use in primary education. Students participated in the research activity in two stages. In the first stage, further referred to as Activity 1, they followed a predetermined algorithm, instructions to construct an electronic device. The instructions for this device were developed to serve as a resource for primary education and to prepare the students for the second stage. In the second stage, further known as Activity 2, the students were tasked with creating a new electronic device together with providing the instructions. The new device was required to have a practical application. Following the completion of these activities, we collected and analyzed the procedural reflections and didactic interpretations from students. Within these interpretations, we also sought their opinions on how STEAM projects like these could help develop various aspects of STEAM competencies in children such as technical skills and knowledge, algorithmic thinking, and device architecture as well as mathematical and scientific thinking.

Kinematics is a fundamental topic in engineering, robotics, mechatronics, and control systems and significantly resolves some of these fields’ most pressing issues. It is essential to assess the balance between a topic’s theoretical framework and its empirical validation to succeed in engineering. Educational tools have gained significant attention for their ability to enhance the learning experience by providing the hands-on experiences necessary to assess theoretical frameworks and empirical validations. This paper presents a system incorporating state-of-the-art features, including a fuzzy controller enabling precise control of a linear actuator and a USB camera, to provide an interactive experience. The USB camera captures the position of the actuator, providing real-time visual feedback and allowing the students to validate their theoretical understanding through practical experiments. Precision, accuracy, resolution, and the implementation of the fuzzy controller are measured to evaluate the whole system’s performance. The design, implementation, and control of our educational electrical linear actuator for teaching kinematics concepts contribute to a practical educational tool and advance interactive learning approaches in the field.
