Testing grip of AMOS, with and without shark skin, on different surfaces.
(A) Two pieces of shark skin installed at the front and central parts of the hexapod walking robot AMOS. The shark skin at the front part has a size of 4 cm wide and 7 cm long while another one at the central part is 4 cm wide and 12 cm long. (B) Diagrams showing the static experiments. (C), (D) A comparison of maximum slope angles before AMOS, with and without shark skin, started to slip on three different surfaces. Average static friction coefficients μ between shark skin and the surface for all tests are calculated from tan h(θmax) and depicted on top of the columns. We performed ten runs for each surface. The error bars represent standard deviation.
