Abstract: A vehicle comprises a rigid longitudinal body having a bottom surface engaging the ground and having spaced first and second ends along a longitudinal axis. The bottom surface includes a convex cross-section along its longitudinal axis. The vehicle includes an oscillation generator having horizontal and vertical force components is mounted adjacent and secured to one of the first and second ends for generating vibratory motions, thereby imparting vibrations to the body. The vibratory motions generated by the oscillation generator alternately lift and propel the vehicle forward.
