Abstract
This paper presents a natural extension of the classical input–output equation of a fourbar spherical linkage to the forward displacement analysis of a 3RRR spherical parallel manipulator As a main result it is obtained a closedform solution represented by a 16thdegree polynomial in terms of only one variable In addition the proposed method works equally well for general geometries and for special geometries of the mobile platform and fixed platform of the manipulator A fully detailed case study is reported
