In recent years, the development of Insect-size flying robot has been expected for narrow place and dangerous environmental research applications. We designed a flying robot using a flapping mechanism by imitating a bee with high flight performance. Analysis of the designed flying robot confirmed flapping at 43[Hz] and generation of lift due to passive feathering. As a result of a lift measurement experiment, generation of 1.48[mN] at 48.8[Hz] near the natural frequency was confirmed.
