The apparatus (500) comprises a stationary first part (100), a movable second part (200), and a link arm mechanism (300) connecting the first part (100) and the second part (200). The first (310) and the second (320) link arm are interconnected with a fifth articulated joint (J5). First ends (311, 321) of the link arms (310, 320) are connected with articulated joints (J1, J2) movably on the first part (100). Second ends (312, 321) of the link arms (310, 320) are connected with articulated joints (J3, J4) on the second part (200). The second part (200) is moved with a first actuator (A1) in a first direction (X1), with a second actuator (A2) in a third direction (Y) and with a third actuator (A3) in a fourth angular direction (±) around the fourth articulated joint (J4). |
