Abstract

Abstract:

The aging of workforce, the low efficiency of artificial pollination and the lack of digital and precise management are current situation of orchards. In order to solve these problems, firstly, the preliminary key technical preparations of multiple unmanned aerial vehicles (multi-UAVs) for pollination were clarified, including the optimized combination of pollinating paternal anther, the commercial storage of anthers and so on. Secondly, targeting the problem of poor pollen spraying uniformity of multi-UAVs for pollination, the cluster approach of multi-UAVs for accurate pollen spraying operation was proposed. Based on target location allocation of UAVs cluster, collision avoidance and cluster queue area path planning, the automatic trajectory planning technologies of multi-UAVs for pollination were designed. Finally, the virtual simulation of 3-unit multi-UAVs for pollination was achieved in Matlab environment. Multi-UAVs for pollination will provide a step ahead theoretical exploration and feasible application scheme for the construction of intelligent, ecological and unmanned farm for precision planting.

Key words: orchard, pollination, multiple unmanned aerial vehicles for pollination, trajectory planning, unmanned farm
