Abstract:
1. An apparatus comprising: a housing; a vibration drive situated within the housing, wherein the vibration drive includes an eccentric load and a rotational motor adapted to rotate the eccentric load; a battery situated within the housing; a switch adapted to selectively connect the battery to the vibration drive; a plurality of legs each having a leg base and a leg tip at a distal end relative to the leg base, wherein the legs are coupled to the housing at the leg base and include at least one driving leg constructed from a flexible material and having a leg base arranged farther forward relative to the leg tip; wherein the vibration drive generates a force that is directed downward and is suitable to deflect the at least one driving leg to cause the apparatus to move in a substantially forward direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load; and wherein the at least one driving leg has an average axial cross-section of at least five percent of a length of the at least one driving leg between the leg base and the leg tip.
