Selecting the ants as research objects,an integrative study on the aspects of mechanics,con- figuration and secretion property of ants pads was carried out.Adhesive force and friction of ants on self-designed testing device were tested.Configurations of smooth ants pads were analyzed using light microscope and scanning electron microscope.Results show that horizontal friction is bigger than verti- cal adhesion,and friction and adhesion increase with the decrease of the secretion.Distribution of insects legs and conformation of pads have influence on adhesion.Pads unfold and fold back during each step.
