- An apparatus comprising: - a body having a top and a bottom; - a vibrating mechanism coupled to the body; and - a plurality of legs each having a leg base proximal to the body and a leg tip distal to the body, wherein the plurality of legs are constructed from a resilient material and have resilient characteristics and extend downwardly from the body and are configured to cause the apparatus to propel across a surface in a forward direction and further configured to cause a portion of the plurality of legs to leave the surface as the apparatus translates in the forward direction generally defined by a longitudinal offset between the leg base and the leg tip as the vibrating mechanism causes the apparatus to vibrate; wherein each leg has a diameter ranging between 5% and 60%, preferably between 15% and 25% of a length of the leg between the leg base and the leg top, characterised in that the apparatus further comprises - a top climber appendage which extends from the body such that a climber appendage tip defined on the climber appendage is positioned above the top of the body substantially centered and is sufficiently large enough to prevent the body from lying on the top of the body, and wherein the climber appendage is a non-rotating vibrating appendage, and wherein the legs extend from the body such that each leg tip is positioned below the bottom of the body; such that the climber appendage and legs are configured to contact opposing surfaces, whereby the climber appendage and legs are configured to apply forces against opposing surfaces to produce a net force in a direction generally defined by the longitudinal offset such that the net force propels the apparatus in the forward direction between the opposing surfaces; and wherein the top climber appendage has a diameter ranging between 5% and 60%, preferably between 15% and 25% of a length of the top climber appendage between the top climber appendage base and the top climber appendage tip. - a body having a top and a bottom; - a vibrating mechanism coupled to the body; and - a plurality of legs each having a leg base proximal to the body and a leg tip distal to the body, wherein the plurality of legs are constructed from a resilient material and have resilient characteristics and extend downwardly from the body and are configured to cause the apparatus to propel across a surface in a forward direction and further configured to cause a portion of the plurality of legs to leave the surface as the apparatus translates in the forward direction generally defined by a longitudinal offset between the leg base and the leg tip as the vibrating mechanism causes the apparatus to vibrate; wherein each leg has a diameter ranging between 5% and 60%, preferably between 15% and 25% of a length of the leg between the leg base and the leg top, characterised in that the apparatus further comprises - a top climber appendage which extends from the body such that a climber appendage tip defined on the climber appendage is positioned above the top of the body substantially centered and is sufficiently large enough to prevent the body from lying on the top of the body, and wherein the climber appendage is a non-rotating vibrating appendage, and wherein the legs extend from the body such that each leg tip is positioned below the bottom of the body; such that the climber appendage and legs are configured to contact opposing surfaces, whereby the climber appendage and legs are configured to apply forces against opposing surfaces to produce a net force in a direction generally defined by the longitudinal offset such that the net force propels the apparatus in the forward direction between the opposing surfaces; and wherein the top climber appendage has a diameter ranging between 5% and 60%, preferably between 15% and 25% of a length of the top climber appendage between the top climber appendage base and the top climber appendage tip. such that the climber appendage and legs are configured to contact opposing surfaces, whereby the climber appendage and legs are configured to apply forces against opposing surfaces to produce a net force in a direction generally defined by the longitudinal offset such that the net force propels the apparatus in the forward direction between the opposing surfaces; and wherein the top climber appendage has a diameter ranging between 5% and 60%, preferably between 15% and 25% of a length of the top climber appendage between the top climber appendage base and the top climber appendage tip.
