    We register close-range depth images of objects using a Swissranger sensor and apply a spring-mass model for 3D object reconstruction. The Swissranger sensor delivers depth images in real time which have, compared with ...
  • A bayesian approach to simultaneously recover camera pose and non-rigid shape from monocular images 

    Moreno-Noguer, Francesc; Porta Pleite, Josep Maria (2016)

    Conference report
    Open Access
    Robots and automation systems have become a valuable partner in several facets of human life: from learning and teaching, to daily working, including health monitoring and assistance. So far, these appealing robot-based ...
  • Action rule induction from cause-effect pairs learned through robot-teacher interaction

    Conference report
    Open Access
    In this work we propose a decision-making system that efficiently learns behaviors in the form of rules using natural human instructions about cause-effect relations in currently observed situations, avoiding complicated ...
  • Action selection for robotic manipulation of deformable objects 

    Cuén Rochín, Saúl; Andrade-Cetto, Juan; Torras, Carme (ESF-JSPS, 2008)
    Conference report
    Open Access
    This paper deals with the manipulation of planar deformable objects for typical service robot applications. Specifically, we present a system that straightens pieces of cloth from any arbitrary initial wrinkle condition ...
  • Action selection for single-camera SLAM 

    Vidal Calleja, Teresa; Sanfeliu Cortés, Alberto; Andrade-Cetto, Juan (2010)
    Article
    Open Access
    A method for evaluating, at video rate, the quality of actions for a single camera while mapping unknown indoor environments is presented. The strategy maximizes mutual information between measurements and states to help ...
  • Adaptive modality selection algorithm in robot-assisted cognitive training 

    Taranovic, Aleksandar; Jevtic, Aleksandar; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    Interaction of socially assistive robots with users is based on social cues coming from different interaction modalities, such as speech or gestures. However, using all modalities at all times may be inefficient as it can ...
  • A linear relaxation technique for the position analysis of multi-loop linkages 

    Porta Pleite, Josep Maria; Ros Giralt, Lluís; Thomas, Federico (2008)
    External research report
    Open Access
    This report presents a new method able to isolate all configurations that a multi-loop linkage can adopt. We tackle the problem by providing formulation and resolution techniques that fit particularly well together. The ...
  • Analysing the singularities of 6-SPS parallel robots using virtual legs 

    Borràs Sol, Júlia; Thomas, Federico; Torras, Carme (LIRMM, 2008)
    Conference report
    Open Access
    A virtual leg in a 6-SPS parallel robot is defined as a leg whose length is determined by the lengths of a subset of the actual legs of the robot. This necessarily implies that this subset of legs defines a rigid subassembly. ...
  • Analysis of methods for playing human robot hide-and-seek in a simple real world urban environment 

    Goldhoorn, Alex; Sanfeliu Cortés, Alberto; Alquézar Mancho, René (Springer, 2013)
    Conference report
    Open Access
    The hide-and-seek game has many interesting aspects for studying cognitive functions in robots and the interactions between mobile robots and humans. Some MOMDP (Mixed Observable Markovian Decision Processes) models and a ...
  • An European vision of network robot systems in urban areas 

    Sanfeliu Cortés, Alberto (NRF, 2008)
    Conference report

  • An open-source toolbox for motion analysis of closed-chain mechanisms 

    Porta Pleite, Josep Maria; Ros Giralt, Lluís; Bohigas Nadal, Oriol; Manubens Ferriol, Montserrat; Rosales Gallegos, Carlos; Jaillet, Leonard Georges (Springer, 2013)
    Conference report
    Open Access
    Many situations in Robotics require an effective analysis of the motions of a closed-chain mechanism. Despite appearing very often in practice (e.g. in parallel manipulators, reconfigurable robots, or molecular compounds), ...
  • A novel path planning proposal based on the combination of deterministic sampling and harmonic functions 

    Rosell Gratacòs, Jan; Vázquez Hurtado, Carlos; Pérez, Alexander; Iñíguez Galbete, Pedro (2007-03)
    External research report
    Open Access
    The sampling-based approach is currently the most successful and yet more promising approach to path planning problems. Sampling-based methods are demonstrated to be probabilistic complete, being their performance reliant ...
  • Anticipating human activities from object interaction cues 

    Aranda López, Juan; Vinagre Ruiz, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Restricted access - publisher's policy
    A real time approach to the recognition of human activity based on the interaction with objects in domestic settings is presented. It is based on capturing partial images where the activity takes place using a color camera, ...
