This paper introduces a hardware platform for automated battery changing and charging for multiple UAV agents. The automated station holds a buffer of 8 batteries in a novel dual-drum structure that enables a " hot " battery swap, thus allowing the vehicle to remain powered on throughout the battery changing process. Each drum consists of four battery bays,(More)

In region coverage, UAVs typically follow a certain pattern of combing through a region. In this paper, we present a turning time model for estimating the time cost for UAV. Based on this, we explore two strategies of scanning as a basis for a memetic computing search: the raster and circular scanning strategies. To our knowledge, there has been no attempt(More)
Preliminary design of high-thrust interplanetary missions is a highly complex process. The mission designer must choose discrete parameters such as the number of flybys and the bodies at which those flybys are performed. For some missions, such as surveys of small bodies, the mission designer also contributes to target selection. In addition, real-valued(More)
