I have looked for a way to make a cyclorotor mechanism which allows the blades to rock/rotate (in the picture below, its rocking I believe) to no avail. I am not able to find the required length of the green link or that green circle (refer picture). Any idea on how to find out the required length? also, how to determine the eccentricity?
The picture drawn using paint was the idea I was working on. Here the blade is supposed to spin by 180 degrees when the whole system completes one rotation with intermediate positions as shown in the figure. I am not able to determine the length of the remaining links to connect the system. I was thinking on the lines of 4 (or is it 5?) bar mechanisms as in two of the links have been given in each quadrant but cant find any logical way to find the remaining links.
