摘要： An apparatus which transforms itself from one form to another. The apparatus comprises a body having a first rotatable leg and a second rotatable leg mounted thereon. When placed in motion, the apparatus is in its first form. First and second links are rotatably mounted in the first and second rotatable legs, respectively. The first and second links are pivotably joined at a pivot point. The apparatus has a weight disposed at the pivot point. Forces acting on the apparatus at different stages of travel cause forces to shift. This causes rotation of the first rotatable leg and said second rotatable leg. When this occurs, the apparatus is transformed into the second form. Also, a center of gravity shifting apparatus shifts the center of gravity of the apparatus from the front of the apparatus to the rear of the apparatus.
