In this study, we developed a quadrupedal passive walking paper toy with the upper and lower bodies separated as a teaching material. The passive walking toy was placed on a slope; by the first swing, it continued walking with torsion of the bodies. We clarified the effects of body size and the body-connecting method with experiments involving the toy walking on a slope. We analyzed bodies' torsional angles and the toy’s operation a frame images analysis characteristic of a 30fps walking movie.
