The present study develops a new propulsion mechanism based on the inertial force. This mechanism is not a pushing away of the land surface but is based on a pulsating lateral inertial force a arising fiom a by shaking mass, and through the difference between the friction coefficient equivalent according to the direction on the ground surface. On this report the dynamic characteristic of the promotion mechanism has been simulated to study relation between the shaking mass and the direction of ground elements.
