    • Finding all valid hand configurations for a given precision grasp 

      Rosales Gallegos, Carlos; Porta Pleite, Josep Maria; Suárez Feijóo, Raúl; Ros Giralt, Lluís (IEEE, 2008)
      Text en actes de congrés
      Accés obert
      Planning a precision grasp for a robot hand is usually decomposed into two main steps. First, a set of contact points over the object surface must be determined, ensuring they allow a stable grasp. Second, the inverse ...

      Rosales Gallegos, Carlos; Porta Pleite, Josep Maria; Ros Giralt, Lluís (The MIT Press. Massachusetts Institute of Technology, 2011)
      Text en actes de congrés
      Accés obert
      This paper presents a procedure to optimize the quality of robotic grasps for objects that need to be held and manipulated in a specific way, characterized by a number of tight contact constraints. The main difficulties ...
    • Grasp optimization under specific contact constraints 

      Rosales Gallegos, Carlos; Porta Pleite, Josep Maria; Ros Giralt, Lluís (2013)
      Article
      Accés obert
      This paper presents a procedure to synthesize highquality grasps for objects that need to be held and manipulated in a specific way, characterized by a pre-specified set of contact constraints to be satisfied. Due to the ...
    • Grasp plannind under task-specific contact constraints 

      Rosales Gallegos, Carlos (Universitat Politècnica de Catalunya, 2013-01-10)
      Tesi
      Accés obert
      Several aspects have to be addressed before realizing the dream of a robotic hand-arm system with human-like capabilities, ranging from the consolidation of a proper mechatronic design, to the development of precise, ...
    • Including virtual constraints in motion planning for anthropomorphic hands 

      Rosell Gratacòs, Jan; Suárez Feijóo, Raúl; Pérez, Alexander; Rosales Gallegos, Carlos (2011)
      Text en actes de congrés
      Accés obert
      This paper copes with the problem of finding a collision-free path for a hand-arm robotic system from an initial unconstrained configuration to a final grasping (or preshape) one. The aim is to obtain a natural motion as ...
    • Motion planning for high DOF anthropomorphic hands 

      Rosell Gratacòs, Jan; Suárez Feijóo, Raúl; Rosales Gallegos, Carlos; García, Jorge Alberto; Pérez Ruiz, Alexander (IEEE, 2009-05-31)
      Text en actes de congrés
      Accés obert
      The paper deals with the problem of motion planning of anthropomorphic mechanical hands avoiding collisions. The proposed approach tries to mimic the real human hand motions, but reducing the dimension of the search ...
    • On the synthesis of feasible and prehensile robotic grasps 

      Rosales Gallegos, Carlos; Suárez Feijóo, Raúl; Gabiccini, Marco; Bicchi, Antonio (IEEE, 2012)
      Text en actes de congrés
      Accés obert
      This work proposes a solution to the grasp synthesis problem, which consist of finding the best hand configuration to grasp a given object for a specific manipulation task while satisfying all the necessary constraints. ...
    • Study of coordinated motions of the human hand for robotic applications 

      Sun, Shao-Chun; Rosales Gallegos, Carlos; Suárez Feijóo, Raúl (2010)
      Text en actes de congrés
      Accés obert
      This paper presents an acquisition method that comprehensively looks for the mimic configurations of the human hand. The data obtained through this process is further analyzed, transformed, and then used to synthesize a ...

      Rosales Gallegos, Carlos; Ros Giralt, Lluís; Porta Pleite, Josep Maria; Suárez Feijóo, Raúl (2011)
      Article
      Accés obert
      This paper presents a new method to solve the configuration problem on robotic hands:deter- mine how a hand should be configured so as to grasp a given object in a specific way, characterized by a number of hand-object ...
    • The CUIK suite: analyzing the motion closed-chain multibody systems 

      Porta Pleite, Josep Maria; Ros Giralt, Lluís; Bohigas Nadal, Oriol; Manubens Ferriol, Montserrat; Rosales Gallegos, Carlos; Jaillet, Leonard Georges (2014)
      Article
      Accés obert
      Many situations in robotics require the analysis of the motions of complex multibody systems. These are sets of articulated bodies arising in a variety of devices, including parallel manipulators, multifingered hands, or ...
