چکیده

This paper proposes techniques to fabricate synthetic gecko foot-hairs for future wall-climbing robots, and models for understanding the synthetic hair design issues. Two nanomolding fabrication techniques are proposed: the first method uses nanoprobe indented flat wax surface and the second one uses a nano-pore membrane as a template. These templates are molded with silicone rubber, polyimide, etc. type of polymers under vacuum. Next, design parameters such as length, diameter, stiffness, density, and orientation of hairs are determined for non matting and rough surface adaptability. Preliminary nano-hair prototypes showed adhesion close to the predicted values for natural specimens (around 100 nN each).

Fabrication of gecko foot-hair like nano structures and adhesion to random rough surfaces∗

In this work the effect of substrate roughness on the adhesion of gecko foot-hair like nano structures as opposed to solid elastic materials is described and models of both synthetic nano-hairs and hair-substrate interaction are developed. First, by combining linear beam theory and geometric constraints, a nonlinear elastic model for the hair is derived. Then it is shown how for a given random ...

Nanomolding Based Fabrication of Synthetic Gecko Foot-Hairs

This paper proposes two different nanomolding methods to fabricate synthetic gecko foot-hair nanostructures. The first method uses Atomic Force Microscope (AFM) probe indented flat wax surface and the second one uses a nano-pore membrane as a template. These templates are molded with silicone rubber, polyamide and polyester type of polymers under vacuum and the template is peeled off or etched ...

Geckobot and Waalbot: Small-Scale Wall Climbing Robots

This paper proposes two small-scale agile wall climbing robots able to navigate on smooth vertical surfaces which use adhesive materials for attachment. Geckobot is a lizard-inspired climbing robot with similar kinematics to a gecko climbing gait. Waalbot uses two actuated legs with rotary motion and two passive revolute joints at each foot. Due to their compact design, a high degree of miniatu...
