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.

Abstract
An apparatus includes a housing, a rotational motor situated within the housing, an eccentric load adapted to be rotated by the rotational motor, and a plurality of legs each having a leg base and a leg tip at a distal end relative to the leg base. The legs are coupled to the housing at the leg base and include at least one driving leg constructed from a flexible material and configured to cause the apparatus to move in a direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load.

34. 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 arranged in two rows and adapted to contact a supporting surface, each of the legs having a leg base and a leg tip at a distal end relative to the leg base, including at least one driving leg constructed from a flexible material; wherein as the vibration drive generates a force that is directed downward and is suitable to deflect the at least one driving leg, the at least one driving leg tends to return to a neutral position to cause the apparatus to move in a substantially forward direction; 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; and wherein at least a portion of the housing is situated between the two rows of legs and extends below the leg base of the plurality of legs. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

61. An apparatus comprising:
-
a housing; a rotational motor situated within the housing; an eccentric load, wherein the rotational motor is adapted to rotate the eccentric load; a plurality of legs each having a leg base and a leg tip at a distal end relative to the leg base, wherein at least a portion of the plurality of legs are; constructed from a flexible material; and include at least one driving leg configured to cause the apparatus to move in a direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load; and wherein each of the plurality of legs has an average axial cross-section of at least five percent of a length of the leg between the leg base and the leg tip and forces from rotation of the eccentric load interact with a resilient characteristic of the at least one driving leg to cause the at least one driving leg to propel the apparatus in a forward direction and to leave a support surface as the apparatus translates in the forward direction, and wherein the legs are arranged in two single file rows, with the leg base of the legs in each row coupled to the housing substantially about a lateral edge of the housing and wherein at least a portion of the housing is situated between the two rows of legs and extends below the leg base of the plurality of legs in the direction of the leg tip of the plurality of legs. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81)
