Abstract: The parallel manipulators are used for many industrial applications, thanks to their better performances: high precision and rigidity, high load capacity and high ratio between payload and net weight. On the other hand, the parallel manipulators suffer of some drawbacks. A very important one is the presence of singularities inside the workspace. It is very well known that the positioning accuracy of the platform of a parallel manipulator decrease with approaching to the singular position. One of the aims of the optimum design of the parallel manipulators is to obtain better performance, regarding the positioning precision of the platform and implicit – of the end – effector, and the decrease of the driving forces. The present paper discuses in detail some aspects of the optimization problem of the parallel manipulator design, so that the positioning accuracy to be maximum.
