    • A Portable Ground-Truth System Based on a Laser Sensor 
      Marchant, Román; Guerrero, Pablo; Ruiz del Solar, Javier (Springer-Verlag, 2012)
      State estimation is of crucial importance to mobile robotics since it determines in a great measure its ability to model the world from noisy observations. In order to quantitatively evaluate state-estimation methods, ...
    • A Real-Time Hybrid Architecture for Biped Humanoids with Active Vision Mechanisms 
      Testart, Javier; Ruiz del Solar, Javier; Schulz, Rodrigo; Guerrero, Pablo; Palma Amestoy, Rodrigo (Springer, 2010)
      A real-time hybrid control architecture for biped humanoid robots is proposed. The architecture is modular and hierarchical. The main robot’s functionalities are organized in four parallel modules: perception, actuation, ...
    • Automatic On-Line Color Calibration using Class- Relative Color Spaces 
      Guerrero, Pablo; Ruiz del Solar, Javier; Fredes Sandoval, Josué Abraham; Palma Amestoy, Rodrigo (2012-12-18)
      In this article we present an automatic on-line color calibration system that makes extensive use of the spatial relationships between color classes in the color space. First, we introduce the definition of class-relative color ...
    • Bayesian Spatiotemporal Context Integration Sources in Robot Vision Systems 
      Palma Amestoy, Rodrigo; Guerrero, Pablo; Ruiz del Solar, Javier; Garretón, Claudio (2012-12-18)
      Having as a main motivation the development of robust and high performing robot vision systems that can operate in dynamic environments, we propose a bayesian spatiotemporal context-based vision system for a mobile robot ...
    • Benchmarks for Robotic Soccer Vision 
      Dodds Rojas, Ricardo; Iocchi, Luca; Guerrero, Pablo; Ruiz del Solar, Javier (2012-12-17)
      Robotic soccer vision has been a major research problem in RoboCup and, even though many progresses have been made so that, for example, games now can run without many constraints on the lighting conditions, the problem ...
    • Explicitly Task Oriented Probabilistic Active Vision for a Mobile Robot 
      Guerrero, Pablo; Ruiz del Solar, Javier; Romero, Miguel (Springer-Verlag, 2009)
      A mobile robot has always uncertainty about the world model. Reducing this uncertainty is very hard because there is a huge amount of information and the robot must focus on the most relevant one. The selection of the most ...
    • Improving Robot Self-Localization using Landmarks’ Poses Tracking and Odometry Error Estimation 
      Guerrero, Pablo; Ruiz del Solar, Javier (2012-12-18)
      In this article the classical self-localization approach is improved by estimating, independently from the robot’s pose, the robot’s odometric error and the landmarks’ poses. This allows using, in addition to fixed ...
    • Probabilistic Decision Making in Robot Soccer 
      Guerrero, Pablo; Ruiz del Solar, Javier; Díaz, Gonzalo (2012-12-18)
      Decision making is an important issue in robot soccer, which has not been investigated deeply enough by the RoboCup research community. This paper proposes a probabilistic approach to decision making. The proposed methodology ...
    • Recovering Latent Signals from a Mixture of Measurements Using a Gaussian Process Prior 
      Tobar Henríquez, Felipe; Ríos, Gonzalo; Valdivia, Tomás; Guerrero, Pablo (IEEE, 2017)
      In sensing applications, sensors cannot always mea-sure the latent quantity of interest at the required resolution, some-times they can only acquire a blurred version of it due the sensor’stransfer function. To recover ...
    • Visitrack: A pervasive service for monitoring the social activity of older adults living at home 
      Gaete, Alonso; Gutiérrez Figueroa, Francisco; Ochoa Delorenzi, Sergio; Guerrero, Pablo; Wyzykowski, André (Springer, 2017)
      Advances in medical science allow people to live longer and more independently than some decades ago. However, this does not directly help older adults improve their mental wellbeing. Several studies show that elderly ...
