The lengths of links 1, 2, and 3 are respectively equal to the lengths of links 6, 5 and 4. Link 1 rotates about fixed axis A and is connected by turning pair C to link 2. Link 2 is connected by turning pair D to link 3. Link 6 rotates about fixed axis B and is connected by turning pair G to link 5. Link 4 is connected by turning pairs E and F to links 3 and 5. The mechanism transmits rotation between any two arbitrarily located axes A and B.
