Figure 6


Fig. 6. Force vs time of representative trials. In all trials, shear velocity was 50 µm s-1. (A) Setal arrays compressed and relaxed vertically. (B) Setal arrays compressed and relaxed against the natural path of drag (`against setal curvature'), opposite to the usual direction for climbing in which they do not adhere. (C) Setal arrays compressed and relaxed along the natural path of drag (`with setal curvature', in the typical orientation that geckos use them to climb.
