Abstract
The invention relates to a robotic device for the positioning and orientation of a platform that is connected thereto by means of articulated support structures forming parallel mechanical links, each in the form of a serial kinematic chain of articulations that are interconnected by support segments. The inventive device () is characterized in that it comprises three articulated parallel mechanical links comprising: (i) two opposing, symmetrical and co-planar support structures (and), and (ii) a third support structure () which is located in a plane that is perpendicular to the plane containing the support structures (and). According to the invention, the articulated links formed by the three supports structures (and) enable the controlled movement of points belonging to the platform () on a surface corresponding to a spherical or ellipsoidal cap and, preferably, essentially to a half-sphere, thereby providing at least five degrees of freedom.
