One of the most striking aspects of learning how to program smart phone applications is the possibility of producing interfaces based on motion and basic human physical skills, instead of bing limited to the usage of keyboards and mice. The present work describes a series of practical exercises, designed to provide students with the required skills to access and process the information generated by smart phone sensors, and to combine them to create natural interfaces.

Bridging the gap from theory to real-world, hands- on experience is an always present challenge in Education. The advent of computers allowed for simulation, a halfway step from theory into practice. In Telecommunications Engineering, Software Defined Radio allows students to design and test wireless equipment in real communication by means of a personal computer connected to a simple, low cost, generic radiofrequency device. The paradigm has changed the approach to wireless equipment and communications protocols design across industry and academia. In Education, it has succeeded in providing students with an experience very similar, if not equal, to what they will face in their professional lives. This approach resulted in a deeper understanding and better ability development than was possible through simulation, since several communication problems (such as those related to radiofrequency propagation) are very difficult to model realistically. Moreover, this approach has proved to be strongly motivating for students, who design systems through a graphical interface by interconnecting blocks with specific functionality, but can later experience the results in real communications. This article describes our teaching experience and lessons learned with Software Defined Radio for Engineering Education. We used GNU Radio, an open and free software framework, complemented with GNU Wireless Network, an extension of our design to support data communications. The paradigm involved both graduate and undergraduate courses in Wireless Communication with strong lab content, undergraduate projects, early research training, and several master thesis.

This work aims to describe and discuss the benefits and learning outcomes detected along four iterations of a learning experience carried out by three institutions: ESADE Business School, IED Istituto Europeo di Design and the Telecom Engineering School of UPC, Universitat Politècnica de Catalunya. Mixed teams of students from the three institutions face open innovation challenges with societal interest through Design Thinking. This study is focused on the learning outcomes of engineering students, compared to the ones obtained by Telecom engineering students that follow standard project-based courses. The students spend 3-4 weeks at IdeaSquare, a creative environment created at CERN Meyrin site in Switzerland, where they can consult and interact with scientists and knowledge transfer experts about possible applications and uses of CERN technologies in the student’s proposed solutions. One example of a prototyped solution is a low-cost sensor-based system to detect malfunction in water wells in Africa, which uses SMS-based communication and cloud-based solutions to manage wells repairs. As a result, the ICT engineering students increase their awareness of user needs and the relevance of the problems to focus on when tackling a complex challenge. They also increase their ability to ideate more disruptive and high-impact solutions thanks to their understanding of the "big picture" based on their interactions with design and business students.

The aim of this paper is to introduce the use of Crumble, an emerging tool, to guide the introduction to educational robotics as the second step in introducing students to robotics. Robotics requires various skills such as systems thinking, programming mentality, active learning, mathematics, science, judgment and decision making, good communication, technological design, complex problem solving and persistence. These skills can be easily developed using Crumble. The results of the educational robotics course demonstrate how children with previous Scratch programming experience, but no physical robot experience can continue the learning process through classroom experiences. The result of this work shows that it is better to adapt the difficulty to each of the children. Finally, it is important to combine theory and practice in order to include fun tasks intertwined with the challenges of applying theory to problem solving.

Power electronics and drives have increased their presence at industry both in renewable energies, power systems and electric traction. For this reason, future electrical engineers need to acquire advanced competences in this field. Although chalk-and-board and slides can be used at degree and master level, the inclusion of game-based activities improve the motivation and life-long learning of students. This paper presents a newly design game to deeply understand the different arrangements and performance of power converter and electric machines. The game-based approach favors the acquisition of cross competences and promotes technical discussion and exposition abilities.

The measurement of magnetic fields is a complex activity, which can be of significant didactical value. The interference of the numerous sources of magnetic field around the measuring site requires a deep understanding of the fundaments of electronic instrumentation and the particularities of the measurement of magnetic fields. The proposed experimental set-up, which makes use of a 3-axes magnetometer controlled from an Arduino board, also gives the students the chance to practice embedded programming.

The most used platforms in technology, programming and robotics learning in secondary schools are LEGO Mindstorms and Arduino. LEGO´S Robotic platforms are distinguished for their simplicity in programming and mechanical assembly, whereas the high price of components is their main drawback. Available sensors and actuators for Arduino are inexpensive, but they are difficult to integrate in a multifunctional mechanical structure. This paper analyses the advantages and disadvantages of the use of the LEGO Mindstorms and Arduino platforms in teaching and presents two alternatives to integrate both worlds taking advantage of each one of them: in the first one, LEGO Mindstorms controls sensors and actuators of commercial nature, even getting to stablish a master-slave communication with Arduino; in the second, Arduino is in charge of controlling the peripherals of LEGO Mindstorms.

The purpose of this paper has been the construction of a low cost robotic prosthesis and its control through the Arduino platform. The implementation of EMG/ECG electromyographic surface sensors has allowed to develop the control of the robotic arm in a simple and effective way. The system has sought to simulate the natural movements of the arm and hand. The EMG sensors serve as a bridge to detect the small electrical pulses produced by muscle activity and transform them into an analog signal that the microprocessor is capable of interpreting. Nowadays, the imminent advances related to robotics and modern control techniques have caused these disciplines of knowledge to be used as an educational complement in basic and higher education. On the other hand, the 3D printing technique has facilitated the modeling of the robotic prosthesis. Final Year Project (TFG) or Final Master Project (TFM), constitutes an academic activity that allows to evaluate in detail the different competences acquired by the students during their university education period. Develop and implement advanced control strategies in robotic elements, by remote or local control, is a clear example of academic work that causes extra motivation in science, technology and engineering students. This paper presents a novel and current electronic application such as the construction of a bionic prosthesis. At the same time, the different details related to its implementation have been discussed. The results obtained have also been obtained.
本文的目的是通过Arduino平台构建一个低成本的机器人假体并对其进行控制。EMG/ECG肌电图表面传感器的实现使机械臂的控制以一种简单有效的方式发展。该系统试图模拟手臂和手的自然运动。肌电图传感器充当桥梁，检测肌肉活动产生的小电脉冲，并将其转换为微处理器能够解释的模拟信号。如今，与机器人技术和现代控制技术相关的迫在眉睫的进步已经使这些知识学科被用作基础教育和高等教育的教育补充。另一方面，3D打印技术为机器人假肢的建模提供了便利。Final Year Project (TFG)或Final Master Project (TFM)是一项学术活动，可以详细评估学生在大学教育期间获得的不同能力。通过远程或本地控制，开发和实施机器人元件的高级控制策略，是学术工作的一个明显例子，它会给科学、技术和工程专业的学生带来额外的动力。本文介绍了一种新颖的电子应用，如仿生假肢的构建。同时，对其实施的不同细节进行了讨论。得到的结果也得到了。

The development of video games has had a great growth in recent years. Also, serious games have positioned themselves as a tool that support the learning process of students. Students from electronic engineering are not the exception. However, video games of this type do not usually consider accessibility parameters in their design and those for electronic engineering are not the exception. On the other hand, several educational institutions use mobile devices in their classrooms for a more didactic learning and to achieve better learning outcomes. This article proposes a mobile serious game that addresses some basic principles of electrical circuits. Also, it incorporates accessibility features for students who have hearing or visual disabilities. Experiments were carried out with people with these types of disabilities to validate their accessibility and they were evaluated to verify their level of learning. Finally, the results obtained were analyzed in order to improve the video game.
