WebSep 23, 2008 · To solve these problems, this work presents a new approach to derive the singularity equation of the Gough–Stewart platform. The main point is that the origin of the mobile frame is separated from the considered point and chosen to coincide with a special point on the platform in order to minimize the geometric parameters defining the platform.

The manipulator structure known as the Stewart-Gough platform has its origin in the design by Stewart of a 6-DOF mechanism to simulate flight conditions by generating general motion in space [1]. Stewart’s mechanism consisted of a triangular
WebMar 25, 2024 · Abstract. The workspace and the dexterity of a Stewart Platform are effected by the choice of its major dimensions, actuators’ stroke and the kinematic constraints of its joints. An investigation of the effects of these parameters on workspace volume of the platform is presented. The obtained results were normalized so that these can be used as …
