The purpose of the present study is to develop micromachines imitating flagellated micro-organisms. The speed of advance, the radius of trajectory and the power consumption of a micromachine are computed by using the boundary element method to optimize seven parameters that express the shape of an actual microorganism and six parameters that stand for the flagellum shape of a micromachine. The optimum cross-sectional shape of the flagellum is an ellipse which is somewhat inclined with respect to the principal normal line of the flagellum spiral. The optimum thickness distribution of the flagellum is such that the position of maximum thickness is very close to the head of the machine. The optimization leads to the reduction of power consumption by 22 percent compared with the power consumed by the actual microorganism.
