Articulated structure intended to allow an object connected to it to be oriented in space. It comprises a fixed mounting plate (1) connected to a movable mounting plate (2) through three arms (3) in which each of the arms (3) comprises two elements (31, 32) articulated to one another by means of a spherical connection (30) and each articulated to one of the mounting plates (1, 2) by a pivot (21); for each of the mounting plates (1, 2) the three pivots have non-parallel axes. Each of the arms (3) is associated with a drive means (4) able to influence the pivoting of one element (31) of the arm (3) with respect to the mounting plate (1). |
