Visual perception for the 3D recognition of geometric pieces in robotic manipulation

During grasping and intelligent robotic manipulation tasks, the camera position relative to the scene changes dramatically because the robot is moving to adapt its path and correctly grasp objects. This is because the camera is mounted at the robot effector. For this reason, in this type of environment, a visual recognition system must be implemented to recognize and “automatically and autonomously” obtain the positions of objects in the scene. Furthermore, in industrial environments, all objects that are manipulated by robots are made of the same material and cannot be differentiated by features such as texture or color. In this work, first, a study and analysis of 3D recognition descriptors has been completed for application in these environments. Second, a visual recognition system designed from specific distributed client-server architecture has been proposed to be applied in the recognition process of industrial objects without these appearance features. Our system has been implemented to overcome problems of recognition when the objects can only be recognized by geometric shape and the simplicity of shapes could create ambiguity. Finally, some real tests are performed and illustrated to verify the satisfactory performance of the proposed system.

Mathematics Game e-Library for Elementary School, study case: Mexico

One of the most relevant subjects for the intellectual formation of elementary school students is Mathematics where its importance goes back to ancient civilizations and which its importance is underestimated nowadays. This phenomenon occurs in Mexico, where 63.1% of the total population of elementary school students between the third and sixth grade have insufficient/elemental level of mathematics knowledge. This has resulted in the need to use a new mechanism to complement student’s classroom learning. With the rapid growth of wireless and mobile technologies, the mobile learning has been gradually considered as a novel and effective form of learning due to it inherits all the advantages of e-learning as well as breaks the limitations of learning time and space occurring in the traditional classroom teaching. This project proposes the use of a Mathematics Game e-Library integrated by a set of games for mobile devices and a distribution/management tool. The games are developed for running on mobile devices and for cover the six competencies related with the mathematics learning approach established in Mexico. The distribution/management tool allows students to reach contents according to their needs; this is achieved through a core engine that infers, from an initial profile, the games that cover the user’s knowledge gaps.

GPLSI Compendium App

GPLSI Compendium App se trata de una aplicación móvil que hará las veces de un sistema de gestión y difusión de contenidos digitales, en la que el usuario podrá realizar resúmenes de textos de diferentes webs, tales como artículos o noticias, y posteriormente compartir esos resúmenes en sus redes sociales o a través del correo. Se le proporcionarán varios métodos de resumen, así como las descripciones y un pequeño tutorial de cómo utilizar la aplicación.

El Mobile Learning en el aula de ELE. Propuestas para el alumnado italófono

Los dispositivos móviles se han convertido en una herramienta irrenunciable en la vida de los seres humanos, principalmente como instrumento para estar en contacto con cualquier persona en cualquier lugar y en cualquier momento. La introducción de los smartphone y las tabletas en las aulas de Educación Secundaria favorece la motivación y la autonomía del alumnado, puesto que las aplicaciones digitales (Apps) son el mundo en el que nace y vive. Sin embargo, el concepto de Mobile Learning se puede aplicar tanto al aula de lengua y literatura para hispanohablantes como al aula de español para extranjeros, empleando el móvil no como sustituto del material en papel, sino como elemento que fomenta las habilidades comunicativas. Teniendo en cuenta la utilidad de las app para dispositivos móviles en las aulas de Español como Lengua Extranjera (ELE), en el presente trabajo se desarrolla una propuesta didáctica desde el área de lengua y literatura española para el alumnado italófono: estos estudiantes constituyen un grupo particular de aprendices de español ya que, como los dos idiomas se parecen, surgen dificultades inesperadas al descubrir las divergencias durante el estudio de la lengua.
