Design And Preparation Of Bionic Material Used On The Foot Of Gecko Robot

Geckos possess extraordinary ability to move on both smooth and rough ground,walls and ceilings.It's demonstrated by scientists that this special adhesion ability is arose by the van der Walls interaction between the"hairy"system on the gecko foot and the contacted surface.If a similary synthetic"hairy"system is fabricated and applied on the robot foot,the robot's capability will be greatly enhanced.A two dimension small scale force sensor is developed which is used in the adhesion and friction tests,the sensor works well in the experiments.Elastic modulus of nine different polyester/silicon rubber mixtures is tested,the results show that mixtures'elastic modulus increases with the aggrandizing of mass percentage of polyester.Mixtures'adhesion abilitiy and especially mixture A's adhesion-friction relationship are tested.These results provide experimental evidences for the fabricating of synthetic gecko hairs.Lastly,a primary analysis of nanoscale hair modle is done,some hair preparation method is introduced,and the synthetic gecko foot hair fabricated by model moulding method is tested.
