    • Robotics-Centered Outreach Activities: An Integrated Approach 
      Ruiz del Solar, Javier (IEEE, 2010-02)
      Nowadays, universities are making extensive efforts to attract prospective students to the fields of electrical, electronic, and computer engineering. Thus, outreach is becoming increasingly important, and activities ...
    • Robust Object Recognition using Wide Baseline Matching for RoboCup Applications 
      Loncomilla, Patricio; Ruiz del Solar, Javier (2012-12-18)
      As the RoboCup leagues evolve, higher requirements (e.g. object recognition skills) are imposed over the robot vision systems, which cannot be fulfilled using simple mechanisms as pure color segmentation or visual sonar. ...
    • Robust tracking of multiple soccer robots using random finite sets 
      Cano, Pablo; Ruiz del Solar, Javier (Springer, 2017)
      Having a good estimation of the robot-players positions is becoming imperative to accomplish high level tasks in any RoboCup League. Classical approaches use a vector representation of the robot positions and Bayesian ...
