Abstract
In this research, attention was paid to the ambival with the water surface as the habitat, and the development of a water surface mobile robot using the surface tension was carried out. In the previous research, it was not an appropriate supporting leg shape to move on the water surface. Therefore, in this study, we propose a method for measuring the water repellency of legs, supporting legs which support water surface more efficiently than the conventional water surface moving robot As a result, the developed water surface mobile robot was able to move independently on the water surface by using the surface tension.The resistance of the leg received from the water surface was measured, and the driving Legs, and supporting legs, and as a result, it was possible to move at more than twice the speed of conventional water surface mobile robots..
