After preprocessing the EMG signal (rectification and linear envelope) obtained from four channels, four different classifiers have been applied to discriminate between flexion, extension, adduction and abduction wrist movements.

They take advantage of the wind at deep seas, where it reaches higher and more constant speed. However, being located in deep waters they are subject to heavy loads, caused mainly by waves and wind. To reduce the vibrations in the structure, passive control devices can be used, which come from civil engineering. But its design and tuning are not a simple task due to the diverse goals that coexist in the application of these passive control systems. In this work the use of different methods of signal analysis for the optimization of TMD devices (Tuned Mass Damper) is explored through genetic algorithms. Various error criteria have been applied for the optimization in order to obtain a greater reduction of vibrations in the various elements of the floating turbine.","PeriodicalId":189601,"journal":{"name":"XL Jornadas de Automática: libro de actas (Ferrol, 4-6 de septiembre de 2019)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116205542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sin embargo, existen ciertas aspectos que limitan un uso mas extendido. Una posible causa puede ser que las mejoras en funcion motora no son traspasadas directamente al desarrollo de actividades de la vida diaria. Esto puede provenir de que las estrategias utilizadas no promueven el entrenamiento de otros factores esenciales en la generacion del movimiento, como el cognitivo y perceptual. En este articulo se presenta una estrategia para la rehabilitacion de la funcion motora de la extremidad superior que utiliza un brazo robotico para modelar la interaccion con el usuario, anadiendo en la tarea factores para la estimulacion cognitiva. El robot es usado para promover la movilizacion del brazo, mientras se propone al usuario manipular y reconocer objetos. Una webcam colocada en el extremo del robot es utilizada para reconocer los objetos. Ademas, los movimientos del usuario son monitorizados por una camara RGB-D para analizar su calidad. En la fase actual de desarrollo se ha completado la integracion de los componentes para la estrategia. La estrategia propuesta esta orientada a implementar tratamientos personalizables, que incluyan factores cognitivos en el mismo paradigma, y en un entorno mas cercano al de la vida diaria. EnglishAt present, the development of robot-aided systems in rehabilitative procedures has been high. However, there are aspects that limit extended use. A possible cause is that motor gains usually are not transferred to the performance of daily living activities. This fact likely is due to current strategies are enough not promoting the training of other relevant aspects involved in motion generation, such as cognition and perception. This paper presents a strategy for the rehabilitation of upper limb motor function using a robotic arm for modelling the human-robot interaction and adding a cognitive load. The robot is used for promoting the user's arm mobilisation and to propose identification and manipulation of objects. A webcam fixed on the robot gripper is employed to identify the objects. User's movements are registered via an RGB-D camera. In the current development stage, the integration of the strategy components has been successfully performed. The proposed strategy aims to implement customisable treatments that include cognitive aspects in the same paradigm, and into environments similar to the quotidian ones.","PeriodicalId":189601,"journal":{"name":"XL Jornadas de Automática: libro de actas (Ferrol, 4-6 de septiembre de 2019)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122784984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the fundamental aspects that allows to achieve this collaboration is the planning of safe routes, in such a way that it is possible to guarantee the free movement of collisions of each one of the vehicles by the work area. For this reason, in this work, it is proposed to plan multiple routes for a swarm of Unmanned Aerial Vehicles based on the creation of Probabilistic Road Maps. The objective is the implementation of a method that allows the construction of safe trajectories for each one of the agents of the swarm when a joint objective is desired, a labeled objective or when there are several objectives to be completed and several vehicles are available to do so ( unlabeled ), demonstrating that probabilistic roadmaps constitute a fast and effective method for the establishment of multiple routes. In addition, it is proposed to integrate this solution in an ROS architecture that allows, in the first instance, to obtain results within the Gazebo simulation environment and, in the future, a simple implementation of the algorithms presented in a real eet of vehicles.
