Link 1 rotates about a fixed axis, parallel to axis Ox, and is connected by screw pair B to link 3. Link 2 rotates about a fixed axis, parallel to axis Oy, and is connected by screw pair C to link 4. Slider 5 moves along cross-piece a of link 3, parallel to axis Oy, and has pin b which slides along slot d of link 4. Slot d is parallel to axis Ox. Turning screws 1 and 2 so that point A, the intersection of the axes of pin b and slot d of links 5 and 4, lies on the given curve y=f(x), the coordinates x and y of this curve can be measured.
