In this study, we constructed a flapping robot based on a hummingbird, measured the change in ascending force according to the size of its wings, and selected an appropriate feather. The created Hummingbird Robot was 7.0 [g], and when the gravitational acceleration of 10 [mN] was converted into a value of 70 [mN], the ascending force was necessary. Since the hummingbird flies by twisting (feathering) of its wings, we fabricated 3 types of feathers in which the area of the feathering part was changed, and conducted experiments. We succeeded in generating a maximum 74 [mN] force from the experimental results. We succeeded in improving the ascending force by increasing the area, but when the area was increased, the force to lift the wind was dispersed, resulting in a decrease in the ascending force due to the flexibility of the material of the wings It resulted in.
