    • 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 ...
    • Solution intervals for variables in spatial RCRCR linkages 

      Celaya Llover, Enric (2019-03-01)
      Article
      Accés obert
      An analytic method to compute the solution intervals for the input variables of spatial RCRCR linkages and their inversions is presented. The input-output equation is formulated as the intersection of a single ellipse with ...
    • Stochastic approximations of average values using proportions of samples 

      Agostini, Alejandro Gabriel; Celaya Llover, Enric (2011)
      Report de recerca
      Accés obert
      In this work we explain how the stochastic approximation of the average of a random variable is carried out when the observations used in the updates consist in proportion of samples rather than complete samples.
    • Visually-guided robot navigation: from artificial to natural landmarks 

      Celaya Llover, Enric; Albarral Garcia, Jose Luis; Jiménez Schlegl, Pablo; Torras, Carme (2007)
      Text en actes de congrés
      Accés obert
      Landmark-based navigation in unknown unstructured environments is far from solved. The bottleneck nowadays seems to be the fast detection of reliable visual references in the image stream as the robot moves. In our research, ...
