摘要
Gecko's excellent adhesion ability is thought to derive from van der Waals force generated between the millions of keratinous hairs/setae and the contact surface.Fabricating highly gecko-inspired foot-hair becomes one of the key technologies to realize the three-dimensional-obstacle-free motion of robot.Researchers have fabricated various gecko-like foot-hair arrays which have leaning,large end,and hierarchical structures.Those significant works are summarized and suggestions for future work are proposed in this paper.
Gecko＇s excellent adhesion ability is thought to derive from van der Waals force generated between the millions of keratinous hairs/setae and the contact surface. Fabricating highly gecko-inspired foot-hair becomes one of the key technologies to realize the three-dimensional-obstacle-free motion of robot. Researchers have fabricated various gecko-like foot-hair arrays which have leaning, large end, and hierarchical structures. Those significant works are summarized and suggestions for future work are pro- posed in this paper.
