An articulated structure for a multi-axis robot includes a base having an arm hinged to the base about a first axis and a forearm hinged to the arm about a second axis parallel to the first axis, and wherein the forearm forms a deformable parallelogram structure which includes two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. The structure also includes a first electric actuator controlling pivoting of the arm about the first axis, a second electric actuator controlling pivoting of the forearm about the second axis, and a third electric actuator mounted directly on one of the base and the arm for controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes.
