Info

Cognate linkages are of different geometry and generate the same coupler curve. The lower left figure is Roberts diagram generating two linkages with identical coupler curve as the original linkage, shown on top. The simulation file shown in the lower right separates the three linkages in the Roberts diagram and animate.
