Distribution of load during cooperative cargo transfer by unmanned aerial vehicles

Greater use of drones is expected both in areas without infrastructure and in urban densely populated areas. A necessary prerequisite for the use of drones is a sufficient level of safety and reliability of their operation. In order to contribute to the safety and reliability of drones, a mathematical model of drone cargo transfer in an uncharacterized environment has been developed. The model describes the transfer of small loads by a pair of drones. The cargo is linked, to both drones, with inextensible ropes. Part of the analysis of cargo transfer by drones has already been performed. During cargo transportation by drones, the generated thrusts generally are different. The load factor is the proportion of the weight carried by one of the drones and it takes the values from 0 to 1. The limit amounts are corresponding to cases where only one of the drones carries cargo, and the amount of 1/2 refers to the case when both drones are equally loaded. Any change in the values of model parameters causes a change in the load factor. Less sensitivity to environmental conditions is associated with greater safety and reliability.
