    La transición a la educación en línea en tiempos del coronavirus ha implicado no sólo el desarrollo de nuevas habilidades y actitudes sino la explosión de la creatividad de infinidad de profesores. De pronto, los maestros nos convertimos en aprendices de magos, y tuvimos que adaptarnos e innovar. Particularmente tuvimos que aprender a descubrir nuevas posibilidades que nos permitiesen cocrear con nuestros estudiantes un rico ecosistema de experiencias de enseñanza-aprendizaje durante la covidianidad. En consecuencia, el objetivo del presente artículo es compartir la experiencia de aprendizaje de la gestión del modelo educativo en línea que hemos bautizado como Conectados +. Por supuesto, se exponen, con el permiso de mis estudiantes, algunas estrategias, dinámicas y actividades de interacción, cocreación y evaluación como la aplicación de un examen en díadas, en la nube y en red, sustentado en la teoría del conectivismo; así como la apropiación y articulación de un conjunto de plataformas (Zoom, Google Drive, Twitter y YouTube) y recursos tecnológicos (Jamboard, Kahoot!, Poll Everywhere y Pinpoint) que conforman el ecosistema de experiencias de enseñanza-aprendizaje de Conectados +.

    This paper presents a distributed evolutionary learning control based on social wound treatment for mobile robot navigation using an integrated multi-robot system comprised of simulated and physical robots. To do so, this work proposes an extension of the population-based metaheuristic wound treatment optimization (WTO) method into a distributed scheme. In addition, this distributed WTO method is implemented on the multi-robot system allowing them to experience the environment in their own and communicate their findings, resulting in an emergence intelligence. We implemented our proposal using the combination of five simulated robots with one physical robot for tuning a navigation controller to move freely in a workspace. Results showed that the solution found by this multi-robot system aims using the output controller in the physical robot for successfully achieving the goal to move the robot around a U-maze, without applying any transfer learning approach. We consider this proposal useful in evolutionary robotics, and of great importance to decrease the gap related to transfer knowledge in robotics from simulation to reality. © 2019 Elsevier B.V.

    Robust fall detectors are needed to reduce the time in which a person can receive medical assistance, and mitigate negative effects when a fall occurs. Robustness in fall detection systems is difficult to achieve given that there are still many challenges regarding performance in real conditions. Fall detection systems based on smartphones present good results following a traditional methodology of collecting data, training and evaluating classification models using the same sensors and subjects, yet fail to experiment and succeed in different realistic conditions. In this paper, we propose a methodology to build a solution for fall detection, and online testing changing the sensors and subjects of evaluation in order to provide a more flexible and portable fall detector. © 2020 IEEE.
