    Abstract
  • To verify the mechanism that locusts adjust their posture in air by flapping wings asynchronously, the air posture adjustment locust-like robot system has been designed which realized the flapping of wings with the crank-rocker structure. The structure characteristics have been analyzed and the wings flapping model has been established. Then, the forces and torques acting on the wings under different flapping frequencies and different amplitudes have been calculated. The influences on the body with synchronous and asynchronous flapping of wings have also been analyzed. Finally, an experimental platform has been built and a series of experiments have been implemented. Results indicate that synchronous flapping of left and right wings does not induce body posture change greatly while different phases of each side of wings will cause the body swing. Furthermore, different flapping amplitudes will induce the body roll and the higher flapping frequency is,the more obvious the body rolling phenomenon is. The experiments have verified the correctness of the mechanism of locust air posture adjustment by the ways of asynchronous wings motion and have provided the basis for the design of the air posture adjustment locust-like robot.
