  • Growth signatures of rosette plants from time-lapse video 

    Dellen, Babette Karla Margarete; Scharr, Hanno; Torras, Carme (2015)
    Article
    Open Access
    Plant growth is a dynamic process, and the precise course of events during early plant development is of major interest for plant research. In this work, we investigate the growth of rosette plants by processing time-lapse ...
  • Using a cognitive architecture for general purpose service robot control 

    Puigbo, Jordi-Ysard; Pumarola Peris, Albert; Angulo Bahón, Cecilio; Téllez Lara, Ricardo (2015-04-03)
    Article
    Open Access
    A humanoid service robot equipped with a set of simple action skills including navigating, grasping, recognising objects or people, among others, is considered in this paper. By using those skills the robot should complete ...
  • ECMR’13 Special Issue 

    Andrade-Cetto, Juan; Frese, Udo; Moritz, Tenorth (2015)
    Article
    Open Access
    This special issue contains extended versions of the best papers from the 6th European Conference on Mobile Robots (ECMR). ECMR is a biennial European forum, internationally open, that allows roboticists throughout Europe ...
  • Online EM with weight-based forgetting 

    Celaya Llover, Enric; Agostini, Alejandro Gabriel (2015)
    Article
    Open Access
    In the on-line version of the EM algorithm introduced by Sato and Ishii (2000), a time-dependent discount factor is introduced for forgetting the effect of the old posterior values obtained with an earlier, inaccurate ...
  • Potential information fields for mobile robot exploration 

    Vallvé Navarro, Joan; Andrade-Cetto, Juan (2015-07-01)
    Article
    Open Access
    We present a decision theoretic approach to mobile robot exploration. The method evaluates the reduction of joint path and map entropy and computes a potential information field in robot configuration space using these ...
  • Non-rigid graph registration using active testing search 

    Serradell, Eduard; Amável Pinheiro, Miguel; Sznitman, Raphael; Kybic, Jan; Moreno-Noguer, Francesc; Fua, Pascal (2015)
    Article
    Open Access
    We present a new approach for matching sets of branching curvilinear structures that form graphs embedded in R^2 or R^3 and may be subject to deformations. Unlike earlier methods, ours does not rely on local appearance ...
  • Planning robot manipulation to clean planar surfaces 

    Martínez Martínez, David; Alenyà Ribas, Guillem; Torras, Carme (2015)
    Article
    Open Access
    This paper presents a new approach to plan high-level manipulation actions for cleaning surfaces in household environments, like removing dirt from a table using a rag. Dragging actions can change the distribution of dirt ...
  • Integrated simulation and optimization scheme of real-time large-scale water supply network: applied to Catalunya case study 

    Sun, Congcong; Puig Cayuela, Vicenç; Cembrano Gennari, Gabriela (2015-01-01)
    Article
    Open Access
    This paper presents an integrated simulation and optimization modeling approach in order to provide the optimal configuration for large-scale water supply systems (LSWSS) in real time. Model predictive control (MPC) has ...
  • Development and implementation of a supervisor strategy and sliding mode control setup for fuel-cell-based hybrid generation systems 

    More, Jerónimo Jose; Puleston, Paul Federico; Kunusch, Cristian; Allué Fantova, Miguel (2015)
    Article
    Open Access
    This paper presents the development and experimental results of a supervisor strategy and a sliding mode control setup to improve the performance of hybrid generation systems. The topology in this study is conformed by a ...
  • Closed-loop inverse kinematics for redundant robots: comparative assessment and two enhancements 

    Colomé Figueras, Adrià; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Article
    Open Access
    Motivated by the need of a robust and practical Inverse Kinematics (IK) algorithm for the WAM robot arm, we reviewed the most used Closed-Loop IK (CLIK) methods for redundant robots, analysing their main points of concern: ...
