    • A multi-robot cooperation strategy for dexterous task oriented teleoperation 

      Hernansanz Prats, Alberto; Casals Gelpi, Alicia; Amat Girbau, Josep (2015-06-01)
      Article
      Open Access
      The use of multiple robots working cooperatively in a redundant way offers new possibilities in the execution of complex tasks in dynamic workspaces. The aim of this work is to increase the range of applicability of ...
    • A physical/virtual anatomical platform for hysteroscopy training 

      Rovira Negre, Ramón; Martínez, R.; Hernansanz Prats, Alberto; Casals Gelpi, Alicia (Università degli Studi di Genova, 2019)
      Conference report
      Open Access
      Minimally Invasive Surgery (MIS), which consists in operating through small orifices, reduces the patients’ pain, complications, recovery time and scarring. However, while providing many benefits, the skills required in ...
    • Assistance strategies for robotized laparoscopy 

      Casals Gelpi, Alicia; Hernansanz Prats, Alberto; Sayols Baixeras, Narcís; Amat Girbau, Josep (Springer, 2020)
      Part of book or chapter of book
      Open Access
      Robotizing laparoscopic surgery not only allows achieving better accuracy to operate when a scale factor is applied between master and slave or thanks to the use of tools with 3 DoF, which cannot be used in conventional ...
    • Improving the development of surgical skills with virtual fixtures in simulation 

      Hernansanz Prats, Alberto; Zerbato, Davide; Gasperotti, Lorenza; Scandola, Michele; Fiorini, Paolo; Casals Gelpi, Alicia (Springer, 2012)
      Conference report
      Restricted access - publisher's policy
      This paper focuses on the use of virtual fixtures to improve the learning of basic skills for laparoscopic surgery. Five virtual fixtures are defined, integrated into a virtual surgical simulator and used to define an experimental ...
    • Multi-robot cooperative platform : a task-oriented teleoperation paradigm 

      Hernansanz Prats, Alberto (Universitat Politècnica de Catalunya, 2016-04-14)
      Doctoral thesis
      Open Access
      This thesis proposes the study and development of a teleoperation system based on multi-robot cooperation under the task oriented teleoperation paradigm: Multi-Robot Cooperative Paradigm, MRCP. In standard teleoperation, ...
    • Optimization criterion for safety task transfer in cooperative robotics 

      Hernansanz Prats, Alberto; Amat Girbau, Josep; Casals Gelpi, Alicia (2009)
      Conference report
      Open Access
      This paper presents a strategy for a cooperative multirobot system, constituting a Virtual Robot. The Virtual Robot is composed of a set of robotic arms acting as only one, transferring the execution of a teleoperated task ...
    • Robots cooperants? 

      Hernansanz Prats, Alberto (2008-02)
      Audiovisual
      Open Access
      Els robots industrials realitzen moviments repetitius i automàtics. A la UPC treballem perquè interaccionin i realitzin així una determinada acció amb els moviments que creguin més adients.
    • SENTISIM: A hybrid training platform for SLNB in local melanoma staging 

      Hernansanz Prats, Alberto; Pieras Morell, Tomas; Ferrandiz Pulido, Lara; Moreno Ramirez, David; Casals Gelpi, Alicia (Università degli Studi di Genova, 2019)
      Conference report
      Open Access
      Sentinel Lymph Node Biopsy (SLNB) has been established as an accurate procedure for regional melanoma staging. SNLB has a diagnostic significance as biopsy-based staging identifies patients with nodal metastases who may ...
