Outline of Final Research Achievements

This study aims to build a flapping robot with four wings, which may achieve hovering. Firstly, the unique mechanism is invented which allows a pair of wings not only to flap but also to feather simultaneously, using a single motor. The appropriate structures to achieve such motions is sought, which are light and able to withstand the dynamic loads. Also, the appropriate torque and the revolution number of the motor is investigated, under which it works quite efficiently. The generated lift is sufficiently large enough to hover. The model to fly is built in which two pairs of wings are placed symmetrically about the center of the body. The model is attached to the rotatable arm which is built to simulate a flight. The wing beating frequencies are controlled to stabilize the pitch angle of the model. The test successfully proved the potential to achieve hovering of the four-wing flapping robot.
