Excellent moving ability of gecko attracted the attention of biologists,mechanists,materialists and engineers for years.Biologists tried to reveal the behaviour and bio-physics principles behind the wonderful locomotion ability,mechanists tried to know how the mechanics play its role during motion,materialists discovered new ways to fabricate the adhesive materials like gecko setae array and engineers has done their best to make geckomimicking robot moving as good as gecko.Here we report our recent studies on the biomimetic of gecko locomotion.We designed an experiment facility and for the first time,synchronously detected the probable contact charge and contact forces at the interfaces of geckos setae and solids when gecko freely moving on a vertical substrate.The results show that contact charge was found of magnitudes range from a few tenth of nano-coulomb to a few nano-coulomb,while the shear force was found from tens to hundreds mN,and the contact charge was found to rise with the increase of the shear forces.A positive correlation between the contact charge and shear forces were also observed.The findings not only validated the practicability of our method,but also provide us clear evidence of electrostatic interactions in the adhesion of setae.We chemically stimulated the abduction behaviour of gecko toes and measured the detaching forces simultaneously.The results show that the energy costed during detaching procedure by toe abduction is much lower than that by peeling,which explained why more than 70%detachments were abduction.In order to understand the locomotion behaviour and dynamics,we designed an experiment to study the behaviour and reaction forces of gecko under of gecko under gravity-balanced circumstance.The results show that gecko adhered on the substrate under micro-gravity and we developed a gecko-mimicking robot climbing on a substrate under micro-gravity by using the role that gecko taken under micro-gravity.We fabricated gecko inspired dry adhesive structures,which based on carbon nanotube array growth and micromodelling technology.Experiments show that CNTs based adhesive structure expressed stronger shear loadcarrying ability but modelling based structure did higher normal load carrying ability.We also show several possible applications of adhesive structures for space station.
