This paper describes a non-tethered flapping robot with resonant-driven wings. We proposed a wing with a thin plate that can be resonated at a low frequency using a small battery mounted on the robot. The thrust force generated by the proposed wings at their resonant frequency was 35 percent larger than that of non-resonant wings. Moreover, the non-tethered robot with four wings was developed for free flight. The phase difference between fore and hind wings was varied from 0 to 180 degrees. The robot with the phase difference of 0 and 90 degrees successfully made a level flight.
