    • 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 ...
    • Yet another approach to the Gough-Stewart platform forward kinematics 

      Porta Pleite, Josep Maria; Thomas, Federico (2018)
      Text en actes de congrés
      Accés obert
      The forward kinematics of the Gough-Stewart platform, and their simplified versions in which some leg endpoints coalesce, has been typically solved using variable elimination methods. In this paper, we cast doubts on whether ...
