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.

First claim

We claim:

1. An apparatus comprising:
a housing;
a vibration drive situated within the housing;
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 secured to a portion of the housing about the leg base and include at least one driving leg 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 vibration drive vibrates the housing; 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.

2. The apparatus of claim 1 wherein the at least one driving leg is further constructed from a flexible material.

3. The apparatus of claim 1 , wherein the vibration drive includes a motor and an eccentric load and wherein the eccentric load is configured to be located toward a front end of the apparatus relative to the at least one driving leg, wherein the front end of the apparatus is defined by an end in the direction of movement.

4. The apparatus of claim 1 , wherein the at least one driving leg is configured to cause the apparatus to repeatedly hop as the vibration drive vibrates the housing.

5. The apparatus of claim 4 , wherein the repeated hopping causes the apparatus to move in the direction generally defined by an offset between the leg base and the leg tip of the at least one driving leg.

6. The apparatus of claim 5 , wherein the vibration drive includes a motor and an eccentric load and wherein the eccentric load includes an inertial load adapted, when the vibration drive vibrates the housing, to cause the at least one driving leg to hop off a flat support surface.

7. The apparatus of claim 1 , wherein one or more of the plurality of legs is adjustable.

8. The apparatus of claim 1 , wherein the housing includes at least one opening corresponding to at least one of the legs, the at least one of the legs being frictionally received within the opening.

9. The apparatus of claim 1 further comprising a center of gravity located vertically between a range of 40%-60% of a distance between an upper portion defined on the housing and a plane defined to pass through the plurality of leg tips to prevent tipping of the apparatus as the vibration drive vibrates the housing.

10. The apparatus of claim 1 , wherein the plurality of legs are arranged in two rows, with each row having at least two legs, the leg base of the legs in each row being aligned substantially abutting each lateral side of the housing.

11. The apparatus of claim 10 , wherein the two rows of legs are further spaced apart to define a lateral stance between the first and second rows of legs, and wherein the apparatus includes a center of gravity located vertically from a support surface at a distance defined between 50% and 80% of the lateral stance to prevent tipping of the apparatus as the vibration drive vibrates the housing.

12. An apparatus comprising:
a housing;
a vibration drive situated within the housing;
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 having a leg base arranged farther forward relative to the leg tip;
a battery situated within the housing; and
a switch adapted to selectively connect the battery to the vibration drive, and
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;
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.

13. The apparatus of claim 12 , wherein the at least one driving leg is constructed from a flexible material.

14. The apparatus of claim 13 , wherein the vibration drive includes an eccentric load and a rotational motor adapted to rotate the eccentric load.

15. The apparatus of claim 12 further comprising a center of gravity located vertically between a range of 40%-60%© of a distance between an upper portion defined on the housing and a plane defined to pass through the plurality of leg tips to prevent tipping of the apparatus as the vibration drive vibrates the housing.

16. The apparatus of claim 12 , wherein the plurality of legs are arranged in two rows, with each row having at least two legs, the leg base of the legs in each row being aligned substantially abutting each lateral side of the housing.

17. The apparatus of claim 13 , wherein the two rows of legs are further spaced apart to define a lateral stance between the first and second rows of legs, and wherein the apparatus includes a center of gravity located vertically from a support surface at a distance defined between 50% and 80% of the lateral stance to prevent tipping of the apparatus during vibration of the vibration drive.

18. The apparatus of claim 13 , wherein the vibration drive includes a rotational motor and an eccentric load, and wherein the rotational motor has an axis of rotation that is substantially parallel to the support surface on which the leg tips of the plurality of legs are resting in a neutral position and the axis of rotation passes within 20% of a center of gravity of the apparatus as a percentage of the height of the apparatus to induce a substantially constant rolling force.

19. The apparatus of claim 13 , wherein the vibration drive includes a rotational motor and an eccentric load, and wherein the housing is configured to facilitate rolling of the apparatus about a longitudinal center of gravity, based on a rotation of the eccentric load, with the apparatus on a substantially flat surface when the legs are not oriented such that a leg tip of at least one leg on each lateral side of the housing contacts the substantially flat surface.
