Twelve-bar linkage for stretch and turn

Input: one of the bars pivoted on the grey base. Length of the grey base bar and the yellow end bar: a Length of blue bar: a Length of green bars: 0.4a + 0.6a Length of orange bars: 0.4a Output: the yellow end bar that moves out and gets horizontal position. The gravity tends to keep the mechanism at stretching position.
