Abstract
The paper describes the development of a variable-wing for an aerial-aquatic mobile robot. When a flood occurred, it is difficult and dangerous for human to approach the house which collapsed in flood water or the car which is carried away by flood water. In order to solve the problem, first the robot approaches the place from air, then move through the water to approach it. This time, we propose a variable-wing with a lock mechanism and a passive double-hinged flapping mechanism to perform on the air and under the water maneuver. Through experimentation, we have checked the variable-wing with the lock mechanism and the passive double-hinged flapping mechanism.
