    • Second order collocation 

      Celaya Llover, Enric (2021)
      Report de recerca
      Accés obert
      Collocation methods for optimal control commonly assume that the system dynamics is expressed as a first order ODE of the form dx/dt = f(x, u, t), where x is the state and u the control vector. However, in many cases, the ...
    • Yet a better closed-form formula for the 3D nearest rotation matrix problem 

      Wu, Jin; Sarabandi, Soheil; Porta Pleite, Josep Maria; Liu, Ming; Thomas, Federico (2021)
      Report de recerca
      Accés obert
      This technical report complements the results recently presented in [1] showing that they can be extended to define an efficient and robust method to determine the rotation matrix nearest to an arbitrary 3 × 3 matrix. This ...
    • A randomized kinodynamic planner for closed-chain robotic systems 

      Bordalba Llaberia, Ricard; Ros Giralt, Lluís; Porta Pleite, Josep Maria (2019)
      Report de recerca
      Accés obert
      Kinodynamic RRT planners are effective tools for finding feasible trajectories in many classes of robotic systems. However, they are hard to apply to systems with closed-kinematic chains, like parallel robots, cooperating ...
    • Kinodynamic planning on constraint manifolds 

      Bordalba Llaberia, Ricard; Porta Pleite, Josep Maria; Ros Giralt, Lluís (2017)
      Report de recerca
      Accés obert
      This report presents a motion planner for systems subject to kinematic and dynamic constraints. The former appear when kinematic loops are present in the system, such as in parallel manipulators, in robots that cooperate ...
    • Sistemes multi-agent 

      Golobardes Ribé, Elisabet; Pérez Quiroga, Javier; Porta Pleite, Josep Maria (1997-05-06)
      Report de recerca
      Accés obert
      In the last years a growing interest has arisen around a new paradigm called (among other names) Agents or Multi-Agents Systems. Its popularity has increased to the point that nowadays almost everyone working in Artificial ...
