  • On average real sliding dynamics in linear systems 

    Olm Miras, Josep Maria; Biel Solé, Domingo; Repecho del Corral, Víctor; Shtessel, Yuri B. (2017-07-01)
    Article
    Accés obert
    It is well known that in implementations of sliding mode controllers using hysteresis comparators, when the hysteresis band amplitude tends to zero the real dynamics tends to the ideal sliding dynamics. However, in real ...
  • A local stability condition for dc grids with constant power loads 

    Arocas Pérez, José; Griñó Cubero, Robert (2017-07-01)
    Article
    Accés obert
    Currently, there are an increasing number of power electronics converters in electrical grids, performing the most diverse tasks, but most of them, work as constant power loads (CPLs). This work presents a sufficient ...
  • First-order synergies for motion planning of anthropomorphic dual-arm robots 

    García Hidalgo, Néstor; Suárez Feijóo, Raúl; Rosell Gratacòs, Jan (2017-07-01)
    Article
    Accés obert
    This paper addresses the problem of designing a planning algorithm for anthropomorphic dual-arm robotic systems to find paths that mimics the movements of real human beings by using first-order synergies (correlations ...
  • ¿Son los robots fácilmente aceptados en la sociedad?

  • Robust dexterous telemanipulation following object-orientation commands 

    Montaño Sarria, Andrés Felipe; Suárez Feijóo, Raúl (2017-09-01)
    Article
    Accés obert
    This paper aims to present a procedure to change the orientation of a grasped object using dexterous manipulation. The manipulation is controlled by teleoperation in a very simple way, with the commands introduced by an ...
  • Robots autónomos diestros como co-trabajadores con operarios humanos 

    Suárez Feijóo, Raúl; Rosell Gratacòs, Jan (2017-06-30)
    Article

  • Task-dependent synergies for motion planning of an anthropomorphic dual-arm system 

    García Hidalgo, Néstor; Suárez Feijóo, Raúl; Rosell Gratacòs, Jan (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-01)
    Article
    Accés obert
    The paper deals with the problem of motion planning for anthropomorphic dual-arm robots. It introduces a measure of the similarity of the movements needed to solve two given tasks. Planning using this measure to select ...
  • Coordination of several robots based on temporal synchronization 

    Montaño Sarria, Andrés Felipe; Suárez Feijóo, Raúl (2016-12-01)
    Article
    Accés restringit per política de l'editorial
    This paper proposes an approach to deal with the problem of coordinating multi-robot systems, in which each robot executes individually planned tasks in a shared workspace. The approach is a decoupled method that can ...
  • Exploiting the robot kinematic redundancy for emotion conveyance to humans as a lower priority task 

    Claret Robert, Josep Arnau; Venture, Gentiane; Basañez Villaluenga, Luis (2017-01-17)
    Article
    Accés restringit per política de l'editorial
    Current approaches do not allow robots to execute a task and simultaneously convey emotions to users using their body motions. This paper explores the capabilities of the Jacobian null space of a humanoid robot to convey ...
  • Switching frequency regulation in sliding mode control by a hysteresis band controller 

    Repecho del Corral, Víctor; Biel Solé, Domingo; Olm Miras, Josep Maria; Fossas Colet, Enric (2016-02-01)
    Article
    Accés obert
    Fixing the switching frequency is a key issue in sliding mode control implementations. This paper presents a hysteresis band controller capable of setting a constant value for the steady-state switching frequency of a ...
  • Grasp quality measures: review and performance 

    Roa Garzón, Máximo; Suárez Feijóo, Raúl (2015-01-01)
    Article
    Accés obert
    The correct grasp of objects is a key aspect for the right fulfillment of a given task. Obtaining a good grasp requires algorithms to automatically determine proper contact points on the object as well as proper hand ...
  • Grasp analysis and synthesis of 2D articulated objects with n links 

    Alvarado Tovar, Noé; Suárez Feijóo, Raúl (2015-02-01)
    Article
    Accés obert
    This paper proposes a solution to the problem of grasp analysis and synthesis of 2D articulated objects with n links considering frictionless contacts. The boundary of each link of the object is represented by a finite set ...
