Six-bar Function Generator

Stephenson II six-bar linkage function generator

Mark Plecnik designed this Stephenson II function generator by specifying eight accuracy points and solving the resulting 22 polynomial equations using the numerical homotopy solver, Bertini. He then used Mathematica to examine the 68,000 roots to find 38 useful linkages. SolidWorks was used to generate the solid model and animate the design.
