Claim Text:
1. A mechanical device comprising: a body formed from a plurality of segments interconnected consecutively at a pivot, the plurality of segments defining at least a front segment, a rear segment and at least one intermediate segment positioned between the front and rear segments; the front segment housing a vibrational motor defined by a rotational motor and an eccentric weight, and wherein the vibrational motor is configured to create vibrational forces when the rotational motor rotates the eccentric weight, the front segment further having at least one pair of front legs extending towards a contact surface, defining a front leg segment, and wherein the front leg segment is configured to cause the front segment to move in a direction based on the vibrational forces created as the rotational motor rotates the eccentric weight; at least one pair of intermediate legs being positioned in the at least one intermediate segment and extending towards a contact surface, defining an intermediate leg segment, and wherein each of the legs from the front and intermediate leg segments has a leg base and a leg tip at a distal end relative to the leg base and wherein the at least one pair of front legs is constructed from a flexible material and each leg of the at least one pair of front 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 wherein the vibrational motor generates a force that is directed downward and is suitable to deflect the least one pair of front legs to cause the front leg segment and thus the mechanical device 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 weight, and wherein the rear and intermediate leg segments being interconnected consecutively at the pivots are configured to move in varying directions as the rotational motor generates the vibrational forces, causing a continuously oscillating shape of the plurality of segments.
