Residual vibration control of artificial pollination sprayer for onboard drones

Manual pollination is an arduous task in farming. To provide an alternative to manual pollination, we developed an artificial pollination sprayer for onboard drones. The sprayer was equipped with a pollen sprayer on a gimbal that could be driven horizontally and vertically. Successful pollination was achieved; however, residual vibrations occurred when the gimbal was driven in the experiment. Thus, we proposed experimentally suppressing the vibration phenomenon by altering the design of a control system of rotational speed in further research. Notably, the control system was able to track reference position signals adequately. This study devised a promising method of pollination.
