    • A roadmap to robot motion planning software development 

      Pérez Ruiz, Alexander; Rosell Gratacòs, Jan (2009-02-23)
      Article
      Accés obert
      PhD programs and graduate studies in robotics usually include motion planning among its main subjects. Students that focus their research in this subject find themselves trapped in the necessity of programming an environment ...

    • An assisted re-synchronization method for robotic teleoperated tasks 

      Pérez Ruiz, Alexander; Rosell Gratacòs, Jan (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Teleoperation tasks are performed at cartesian evel when the robot and the haptic device ave dissimilar inematics. If the size of the workspaces is also dissimilar, as it is usually the case, the mapping between workspaces ...

    • Asistencia háptica basada en planificación de movimientos para la teleoperación cooperativa de sistemas multirobot 

      Pérez Ruiz, Alexander (Universitat Politècnica de Catalunya, 2012-10-17)
      Tesi
      Accés obert
      This work proposes a framework for the teleoperation of anthropomorphic industrial robots using desktop haptic devices that provides an aid to the operator in the form of haptic guidance based on path planning techniques. ...

    • Efficient motion planning for high DOF hands using principal motion directions 

      Rosell Gratacòs, Jan; Suárez Feijóo, Raúl; Rosales Gallegos, Carlos; García, J.A.; Pérez Ruiz, Alexander (2008-10)
      Report de recerca
      Accés obert
      The paper deals with the problem of motion planning of anthropomorphical mechanical hands avoiding collisions. The proposed approach tries to mimic the real human hand workspace, but reducing the dimension of the search ...

    • Efficient search of obstacle-free paths for anthropomorphic hands 

      Suárez Feijóo, Raúl; Rosell Gratacòs, Jan; Pérez Ruiz, Alexander; Rosales Gallegos, Carlos (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-10-11)
      Text en actes de congrés
      Accés obert
      The planning of collision-free motions of a handarm system to reach a grasp or preshape configuration is not a simple issue due to the high number of involved degrees of freedom. This paper presents an efficient sampling-based ...

    • Haptic aids for bilateral teleoperators 

      Pérez Ruiz, Alexander; Rosell Gratacòs, Jan (Springer, 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Teleoperation of robotic tasks is usually performed in the Cartesian space due to the kinematic differences between the master and the slave. This entails several requirements, like the definition of a proper mapping between ...

    • Mobile manipulators as robot co-workers: autonomy and interaction in the human-robot collaboration 

      Rosell Gratacòs, Jan; Nuño, Emmanuel; Claret, Josep A.; Zaplana Agut, Isiah; García Hidalgo, Néstor; Akbari, Aliakbar; Ud Din, Muhayy; Palomo Avellaneda, Leopold; Pérez Ruiz, Alexander; Mas Casals, Orestes Miquel; Basañez Villaluenga, Luis (Comité Español de Automática (CEA-IFAC), 2017)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In work environments, the use of dexterous mobile manipulators as co-workers poses several challenges with respect to the human-robot collaboration. On the one hand, its focus is in the autonomy (i.e. the mobile manipulators ...

    • 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 ...

    • Motion planning for the virtual bronchoscopy 

      Rosell Gratacòs, Jan; Pérez Ruiz, Alexander; Cabras, Paolo; Rosell, Antoni (IEEE, 2012)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Bronchoscopy is an interventional medical procedure employed to analyze the interior side of the human airways, clear possible obstructions and biopsy. Using a 3D reconstruction of the tracheobronchial tree, Virtual ...

    • Path planning for grasping operations using an adaptive PCA-based sampling method 

      Rosell Gratacòs, Jan; Suárez Feijóo, Raúl; Pérez Ruiz, Alexander (2013-07-01)
      Article
      Accés obert
      The planning of collision-free paths for a handarm robotic system is a difficult issue due to the large number of degrees of freedom involved and the cluttered environment usually encountered near grasping configurations. ...

    • The Kautham Project: A teaching and research tool for robot motion planning 

      Rosell Gratacòs, Jan; Pérez Ruiz, Alexander; Akbari, Aliakbar; Ud Din, Muhayy; Palomo Avellaneda, Leopold; García Hidalgo, Néstor (Institute of Electrical and Electronics Engineers (IEEE), 2014)
