Abstract: The adhesion mechanism of gecko foot is of great significance to the development of space robot foot. In this paper, based on the adhesion model between a single seta and smooth surface, the distribution model of satellite rough surface, the contact probability and adhesion model between the seta and satellite rough surface, the adsorption capacity of gecko bristle array to satellite surface is calculated and analyzed. It is found that under certain conditions, simulated gecko bristle array can adhere to the satellite surface in the weightlessness environment of space. It is of significance for the research and development of the climbing robot and pipeline robot in space.

Key words: simulated gecko bristle array, satellite surface, adsorption capacity
