Abstract
An apparatus hovering winged objects. The apparatus includes an elongate support and a driver with an output shaft that supports a first end of the support. The driver imparts an oscillating displacement to the first end of the support. A body is mounted at a second end of the support and wings are attached to the support at an offset distance from the body. The body is positioned near the second end to swivel or pivot in response to vibration of the support. The driver vibrates the first end at a frequency that shapes the support as a wave, and the frequency is selected or tuned such that the wings are displaced more than the body such by imparting a harmonic frequency on the support. The output shaft is positioned by the driver in angular positions to move the first end of the support and the body and wings.
