The inverse kinematics solutions of a 7 DOF robotic arm using Fuzzy Logic
2012
This paper focuses on modeling resolving and simulations of the inverse kinematics of an anthropomorphic redundant robotic structure with seven degrees of freedom and a workspace similar to human arm. Also the kinematical model and the kinematics equations of the robotic arm are presented. A method of resolving the redundancy of seven degrees of freedom robotic arm is presented using Fuzzy Logic toolbox from MATLAB®.
3D models of humanoid soccer robot in USAR sim and robotics studio simulators
2008
This paper describes our experience in the simulation of humanoid soccer robots using two general purposes 3D simulators, namely USARSim and Microsoft Robotics Studio. We address the problem of the simulation of a soccer match among two teams of small humanoid robots in the RoboCup Soccer Kid-Size Humanoid competitions. The paper reports the implementation of the virtual models of the Robovie-M humanoid robot platform in the two simulators. Robovie-M was the robot used by our team "Artisti" in the RoboCup 2006 competitions. This paper focuses on the procedures needed to implement the virtual models of the robot and in the details of the models. We describe experiments assessing the feasibi…
Localization of 2D Cameras in a Known Environment Using Direct 2D-3D Registration
2014
International audience; In this paper we propose a robust and direct 2D-to- 3D registration method for localizing 2D cameras in a known 3D environment. Although the 3D environment is known, localizing the cameras remains a challenging problem that is particularly undermined by the unknown 2D-3D correspondences, outliers, scale ambiguities and occlusions. Once the cameras are localized, the Structure-from-Motion reconstruction obtained from image correspondences is refined by means of a constrained nonlinear optimization that benefits from the knowledge of the scene. We also propose a common optimization framework for both localization and refinement steps in which projection errors in one v…
Un cuento de robots : La hija cibernética de descartes
2021
French philosopher René Descartes is today valued as a forerunner of the studies of human mind, artificial intelligence and robotic systems. Throughout his work there are large references to automata and the possibility of artificial life, as well as an assessment of the differences between rational behavior of human beings and the purely mechanical of animals and automata. In addition to these references, there is a fable about the creation by the philosopher of an automaton that replicated his deceased daughter Francine, a story that is well known among the French and Anglo-Saxon specialists, but not so much in the Spanish ones, which is what settles this short work
El pensamiento computacional en contextos educativos: una aproximación desde la Tecnología Educativa
2019
El pensamiento computacional ha vivido un resurgir en los últimos años, en los que la comunidad científica y educativa ha puesto su foco de interés sobre él como un aspecto relevante a incorporar de manera curricular. No obstante, la falta de consenso respecto a qué es y cómo trabajarlo tiene como resultado que se aborde de diferentes formas en la educación, lo que repercute directamente en el aprendizaje del alumnado. Desde enfoques más técnicos, que tienen el riesgo de no permitir aprovechar el potencial que tiene de ser integrado en la estrategia didáctica del docente, a enfoques más transversales, que sí profundizan en las posibilidades que tiene en el ámbito de la didáctica, pero que a…
Derecho de la Inteligencia Artificial. Un enfoque global de responsabilidad desde la ética, la seguridad y las nuevas propuestas reguladoras europeas
2022
La inteligencia artificial integra un conjunto de tecnologías que está cambiando y cambiará el mundo que conocemos. El potencial de la inteligencia artificial es inmenso. Los retos y riesgos que plantea pueden tener un enorme impacto, especialmente en el ámbito ético, jurídico, social, económico y de la seguridad, por lo que ni política ni jurídicamente pueden obviarse y deben ser conocidos, acometidos y gestionados adecuadamente, dado que, de otro modo, la inteligencia artificial se podría convertir en un medio para la desigualdad, el control y la destrucción. Las respuestas a estos retos y riesgos exigen profundos análisis y reflexiones desde todas las dimensiones a un ritmo síncrono, y p…

Not So Much Societal: The Catholic Church in Poland as a Veto Player
2021
George Tsebelis distinguished two forms of veto players’ actions: institutional and partisan. In a democracy, the Church is not able to play either role because it is not an element of the state’s institutional structure. This was the source for Simon Fink’s proposal to look at the Church as a societal veto player (VP). The case of Poland shows, however, that such an approach becomes inadequate in numerous situations. The Church’s influence on political parties, and particularly the state’s institutions, may be exerted outside society. Performed on the basis of the existing literature and political debates conducted since 1989, the analysis of the social and political reality of Poland all…
An ASSOM neural network to represent actions performed by an autonomous agent
1997
An ASSOM neural network to describe the action performed by an autonomous reactive agent is proposed. The neural network receives in input the sequences of data acquired by the agent internal sensors and it classifies them by generating the corresponding symbolic assertions. Experimental results performed on a RWI B12 autonomous robot are reported.
