Abstract
We have developed various passive dynamic walkers. As a result, it is not so difficult to develop a three dimentional passive dynamic walker made of cardboards from our experience. Since the cardboards can easily cut by a box-cutter and stick together, students of primaly school are able to make the walker easily. The purpose of the paper is, hence, to propose a design method of the passive dynamic walker made of cardboard and to introduce some events at primaly schools in order to validate the effectiveness of our method.
