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 obertThe 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 obertThe 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 ... -
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 obertPlanning 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 ... -

Global optimization of robotic grasps
Rosales Gallegos, Carlos; Porta Pleite, Josep Maria; Ros Giralt, Lluís (The MIT Press. Massachusetts Institute of Technology, 2011)
Text en actes de congrés
Accés obertThis 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 obertThis 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 obertSeveral 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 obertThis 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 ... -
