Abstract:
1. An apparatus comprising: a body having two lateral sides traversing a longitudinal axis of the body; a rotational motor coupled to the body; an eccentric load, wherein the rotational motor is adapted to rotate the eccentric load; and 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 body at the leg base and include at least one driving leg having 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 configured to cause the apparatus to move in a forward direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load, wherein a relative length of at least two specific legs of the plurality of legs is configured to alter a tendency of the apparatus to turn, and wherein the plurality of legs are arranged in two rows, with each row having at least two legs, and wherein each leg is coupled to the body such that the leg base of the plurality of legs substantially abut one of the lateral sides of the body, and wherein the body further includes a portion extending between the two rows of legs and said portion extends below the leg base of each of the plurality of legs.
