This paper deals with the development of an efficient method for synthesizing crank-rocker mechanisms that are capable of generating perceptually simple and smooth paths that can be approximated by the first and second harmonics of Fourier series. Through the harmonic analysis of the loop closure equations of the crank-rocker mechanism, analytical relations among the nine design variables are identified. This reduces the dimensions of the search space to two and thereby greatly speed up the synthesis process.
