    • Técnicas de control para la mejora de la estabilidad en redes eléctricas DC con convertidores operando a potencia constante 

      Arocas Pérez, José (Universitat Politècnica de Catalunya, 2022-05-18)
      Tesi
      Accés obert
      Some electrical devices in direct current (DC) networks, under certain operating characteristics, behave as constant power loads (CPLs). This behavior is defined by presenting negative incremental resistance, compromising ...
    • Object manipulation based on tactile information 

      Montaño Sarria, Andrés Felipe (Universitat Politècnica de Catalunya, 2021-03-18)
      Tesi
      Accés obert
      In-hand dexterous manipulation of an object is the ability to change the configuration (position and/or orientation) of an object held in the hand. This is an ability that has allowed humans to use tools and interact with ...
    • Knowledge representation and reasoning for perception-based manipulation planning 

      Diab, Mohammed (Universitat Politècnica de Catalunya, 2021-01-22)
      Tesi
      Accés obert
      This thesis develops a series of modeling and reasoning tools for knowledge-oriented manipulation planning in semi/unstructured environments. The main idea is to use high-level knowledge-based reasoning to capture a rich ...
    • The robot null space : new uses for new robotic systems 

      Claret Robert, Josep Arnau (Universitat Politècnica de Catalunya, 2019-10-02)
      Tesi
      Accés obert
      This doctoral thesis deals with the use of the robot redundancy to execute several tasks simultaneously at different levels of priority and its application to two different robotic systems. In particular, new uses of the ...

      Tesi
      Accés obert
      Motion planning is a traditional field in robotics, but new problems are nevertheless incessantly appearing, due to continuous advances in the robot developments. In order to solve these new problems, as well as to improve ...
    • Solving robotic kinematic problems : singularities and inverse kinematics 

      Zaplana Agut, Isiah (Universitat Politècnica de Catalunya, 2018-09-14)
      Tesi
      Accés obert
      Kinematics is a branch of classical mechanics that describes the motion of points, bodies, and systems of bodies without considering the forces that cause such motion. For serial robot manipulators, kinematics consists of ...
