In this paper, a new method to produce the functional continuum is proposed. The method is a topological optimization technique based on the function of a continuum and is composed of three steps. First, an initial mechanism model, which conforms to the given function, is determined using the Evolutionary L System (ELS). The ELS is a technique to obtain the optimum shape using L system and the genetic algorithms. The obtained mechanism model is changed to a framed structure as Rahmen model in the second step. The cross-section and length of members in the framed structure are optimized to maintain the original design requirement. In the final step, the framed structure is changed to the functional continuum using some well known shape optimization techniques. This method is applied to two problems of functional continuum. The first problem is to produce a device of which the displacement expands into the same direction. The second problem is to produce a microgripper of two fingers for the use in the medical fields. From the results, it is obvious that the proposed method is very useful to produce the functional continuum.
