Abstract: We have developed the fabrication process of superhydrophobic surface with micro/nano texturing method. The contact angle of micro-pyramid was 165.1° after the PTFE coating. The textured surface was applied to feet of Water Strider Robot (WSR). The proposed WSR has Micro Controller Unit (MCU), servo motor and wireless communication module and for the remote control, any PC with Bluetooth module can be used. The control command is given by a user in the hyperterminal which is a default program in the windows operating system. From the results, we know that the moving time was improved in 0.32 s because of the hydrophobicity coating. Therefore, the Poly Tetra Fluoro Ethylene (PTFE) coated surface can be successfully applied to reduce the moving time of the water strider robot.
