The invention relates to spherical robot system for the medical recovery of the upper limb proximal area, having three active couplings with a view to reproducing the abduction and flexion of the shoulder in horizontal and vertical plane, respectively, and reproducing the pronation of the forearm in vertical plane. According to the invention, the robot is a mechanism with three degrees of mobility, in modular construction, consisting of a spherical mechanism with two degrees of mobility which reproduces the movements on the surface of a sphere in the vertical plane YOZ and horizontal plane XOY, the two movements achieving the mobilization of the shoulder joint, where the gearmotor (1) transmits the rotary motion, from the level of the active coupling q1, by means of the rod (2), towards the guiding profile (3) which, in its turn, transmits the motion to the guide slide (4), said slide performing a translation motion in the plane YOZ by sliding on the guide (5), reproducing the flexion/extension of the shoulder, and the gearmotor (6) also transmits a rotation motion, from the level of the active coupling q2, by means of the rod (7), towards the guiding profile (5) and the rod (2) as shoulder supporting element, such that the guide (5) makes the guide slide (4) slide in the plane XOY, together with the support (8) of the arm, the support (9) of the forearm and the support (10) of the hand, consequently, on the guide (3), there being reproduced the abduction/adduction of the shoulder, and a mechanism with one degree of freedom, which reproduces a rotational motion about the axis Y in the plane XOZ for which the gearmotor (11) transmits a rotation motion, from the level of the active coupling q3 to the toothed gear (12), which, by means of some rods (13), transmits the rotation about the axis Y to the atachment elements/ the support (9) of the forearm and the support (10) of the hand, thus reproducing the pronation/supination of the forearm.Invenţia se referă la un sist
