Abstract
A toy beetle which travels down a vertical surface under the influence of gravity has four movable limbs which are arranged in pairs at opposite ends of an axle that is rotatable about a transverse axis of the beetle. Sticky materials at the ends of the limb adhere temporarily to the vertical surface in use. According to the orientation of the beetle with respect to the vertical the beetle will either, in somewhat random fashion, walk or tumble down the surface.
