Board games as a teaching tool for technology classes in Compulsory Secondary Education

Aquest treball estudia la tècnica coneguda com game-based learning, és a dir, l’ús dels jocs com a eina didàctica. Primer que res, es fa recerca sobre els treballs ja existents i es veu que, tot i haver-hi articles sobre game-based learning, és difícil trobar-ne de relacionats amb la tecnologia, més enllà d’ensenyar a programar. A continuació, es revisen els continguts curriculars i les competències de secundària i es relacionen amb alguns jocs de taula ja existents, dels quals es detallen breument les regles de joc. Es veu que hi ha continguts curriculars, pels quals es difícil trobar un joc que hi encaixi. A més a més, es desenvolupa la idea d’un nou joc de taula, basat en el ja existent Party & Co., per treballar alguns dels continguts curriculars pels quals no s’ha trobat cap joc existent que s’hi escaigui. Finalment, s’explica una experiència duta a terme durant el període de pràctiques en el centre escolar al curs de 3r d’ESO. Es disposava de tres grups i en tots tres es va seguir la mateixa programació: classe introductòria expositiva, una sessió de muntatge de robots LEGO, 4 sessions de programació i un petit test. En un dels tres grups, però, es va fer una classe prèvia extra on es va jugar a un joc de taula anomenat RoboRally. Els objectius eren dobles: que aprenguessin la importància de l’algorísmica i que s’ho passessin bé. Els resultats mostren que aquest grup va treballar més i millor. En el treball s’analitzen els resultats obtinguts

This Far, No Further: Introducing Virtual Borders to Mobile Robots Using a Laser Pointer

We address the problem of controlling the workspace of a 3-DoF mobile robot. In a human-robot shared space, robots should navigate in a human-acceptable way according to the users' demands. For this purpose, we employ virtual borders, that are non-physical borders, to allow a user the restriction of the robot's workspace. To this end, we propose an interaction method based on a laser pointer to intuitively define virtual borders. This interaction method uses a previously developed framework based on robot guidance to change the robot's navigational behavior. Furthermore, we extend this framework to increase the flexibility by considering different types of virtual borders, i.e. polygons and curves separating an area. We evaluated our method with 15 non-expert users concerning correctness, accuracy and teaching time. The experimental results revealed a high accuracy and linear teaching time with respect to the border length while correctly incorporating the borders into the robot's navigational map. Finally, our user study showed that non-expert users can employ our interaction method.Comment: Accepted at 2019 Third IEEE International Conference on Robotic Computing (IRC), supplementary video: https://youtu.be/lKsGp8xtyI

Mobile Robot Lab Project to Introduce Engineering Students to Fault Diagnosis in Mechatronic Systems

This document is a self-archiving copy of the accepted version of the paper. Please find the final published version in IEEEXplore: http://dx.doi.org/10.1109/TE.2014.2358551This paper proposes lab work for learning fault detection and diagnosis (FDD) in mechatronic systems. These skills are important for engineering education because FDD is a key capability of competitive processes and products. The intended outcome of the lab work is that students become aware of the importance of faulty conditions and learn to design FDD strategies for a real system. To this end, the paper proposes a lab project where students are requested to develop a discrete event dynamic system (DEDS) diagnosis to cope with two faulty conditions in an autonomous mobile robot task. A sample solution is discussed for LEGO Mindstorms NXT robots with LabVIEW. This innovative practice is relevant to higher education engineering courses related to mechatronics, robotics, or DEDS. Results are also given of the application of this strategy as part of a postgraduate course on fault-tolerant mechatronic systems.This work was supported in part by the Spanish CICYT under Project DPI2011-22443

Children, Humanoid Robots and Caregivers

This paper presents developmental learning on a humanoid robot from human-robot interactions. We consider in particular teaching humanoids as children during the child's Separation and Individuation developmental phase (Mahler, 1979). Cognitive development during this phase is characterized both by the child's dependence on her mother for learning while becoming awareness of her own individuality, and by self-exploration of her physical surroundings. We propose a learning framework for a humanoid robot inspired on such cognitive development

Building ArtBots to attract students into STEM learning

There is an increasing worldwide demand for people educated into science and technology. Unfortunately, girls and underprivileged students are often underrepresented in Science, Technology, Engineering and Mathematics (STEM) education programs. We believe that by inclusion of art in these programs, educational activities might become more attractive to a broader audience. In this work we present an example of such an educational activity: an international robotics and art week for secondary school students. This educational activity builds up on the project-based and inquiry learning framework. This article is intended as a brief manual to help others organise such an activity. It also gives insights in how we led a highly heterogeneous group of students into learning STEM and becoming science and technology ambassadors for their peers
