The patent relates to a vibratory locomotion device which consists of one or more skids resting on the ground supporting a payload, and a vibrating mass attached to the skid. The mass, operated by a motor which creates a sinusoidal oscillation, alternatively pulls and pushes on the skid at a predetermined angle to the ground as it vibrates. When the mass is at the top of its stroke, it lifts and pulls forward on the skid and, when it is at the bottom of its stroke, it pushes downward and backward on the skid. Since the downward force increases the normal and, hence, the available friction force, the angle of the mass to the ground can be adjusted so that no backward slide results. As a result of the vibration of the mass, the skid incremently shuffles forward along the ground.
