Closed-form solution to the position analysis of Watt–Baranov trusses using the bilateration method
Rojas Libreros, Nicolás Enrique; Thomas, Federico (ASME PRESS, 2011)
Article
Accés restringit per política de l'editorialThe exact position analysis of a planar mechanism reduces to compute the roots of its characteristic polynomial. Obtaining this polynomial almost invariably involves, as a first step, obtaining a system of equations derived ... -
Distance-based position analysis of the three seven-link Assur kinematic chains
Rojas Libreros, Nicolás Enrique; Thomas, Federico (2011-02)
Article
Accés obertThe position analysis of planar linkages has been dominated by resultant elimination and tangent-half-angle substitution techniques applied to sets of kinematic loop equations. This analysis is thus reduced to finding ... -

Rojas Libreros, Nicolás Enrique; Thomas, Federico (2012)
Article
Accés obertThe exact position analysis of a planar mechanism reduces to compute the roots of its characteristic polynomial. Obtaining this polynomial usually involves, as a first step, obtaining a system of equations derived from ... -
The forward kinematics of 3-RPR planar robots: a review and a distance-based formulation
Rojas Libreros, Nicolás Enrique; Thomas, Federico (2011)
Article
Accés obertThe standard forward kinematics analysis of 3-RPR planar parallel robots boils down to computing the roots of a sextic polynomial. There are many different ways to obtain this polynomial but most of them include exceptions ... -
The octahedral manipulator revisited
Rojas Libreros, Nicolás Enrique; Borràs Sol, Júlia; Thomas, Federico (IEEE, 2012)
Text en actes de congrés
Accés obertIn most practical implementations of the Gough- Stewart platform, the octahedral form is either taken as it stands or is approximated. The kinematics of this particula r instance of the Gough-Stewart platform, commonly ... -
The univariate closure conditions of all fully parallel planar robots derived from a single polynomial
Rojas Libreros, Nicolás Enrique; Thomas, Federico (2013-06)
Article
Accés restringit per política de l'editorialThe real roots of the univariate polynomial closure condition of a planar parallel robot determine the solutions of its forward kinematics. This paper shows how the univariate polynomials of all fully parallel planar robots ... -
