This paper presents a realization of flapping motion using twist drive mechanism for a bird-like robot. Most of flapping flight robots realize flapping motion by converting the rotating force of motors to the up-and-down motion of the wing by using the crank mechanism or servo motors. However, the wings of actual birds move up and down by contracting the pectoralis major muscle and supracoracoideus muscle alternately. Therefore, in this research, we focus on twist drive mechanism which is light weight and can generate tensile force. A twist drive mechanism is a drive system that the driving force of a motor is used as a rotational force for twisting a cord and converted into a tensile force like a muscle. In this research, we realize flapping motion using twist drive mechanism.
