A device for a body's (1) spherical motion control connected with a frame (5) by means of a spherical joint (2) arranged on a shank connecting the body (1) with the frame (5) and through actuating arms (3) with drives (4), where the shank is sectional and the spherical joint (2) is arranged between the first part (9) of the shank which is firmly fixed to the frame (5) and the second part (10) of the shank which is firmly fixed to the body (1), whereas the number of parallel arms (3) with drives (4) is redundant. In order to increase the accuracy of both the self-calibration itself and a follow-up positioning of the body in the work area and to achieve a large range of the body's (1) rotating, the number of parallel arms (3) with drives (4) is five at minimum and the length of the first part of the shank (9) connected to the frame (5) is longer than the distance of the body (1) edge from the point of connection of the shank (10) to the body (1).
