In recent decades, the devastating earthquakes, which can damage a lot of houses and buildings, have fre- quently happened. To slow down or prevent the disastrous damages of the earthquake, the various technologies have been required. Of these technologies, the ground motion simulator of the earthquake is used to alert people to the dangers of the earthquake. The authors have developed a potable earthquake simulator, called a Zishin-The-Vuton, which has the function to make holonomic omni-directional motions of the earthquake on a plane. In this paper, the more advanced simulator Zishin-The-Vuton 3D is presented. It realizes the up-and-down motion with the holonomic omni-directional motions in order to simulate three-dimensional ground motion of the earthquake. Focusing on the design concept, structure, and feature of this new simulator, we discuss its implementation and validity.
