Unmanned aerial vehicles (UAVs) are an important tool to track the long-distance movement of plant pathogens above crop fields. Here, we describe the use of a control strategy (coordination via speed modulation) to synchronize two autonomous UAVs during aerobiological sampling of the potato late blight pathogen, Phytophthora infestans. The UAVs shared(More)
This paper is concerned with path planning for an autonomous flight vehicle operating in a steady, uniform flow-field. We model the vehicle as a particle that travels in the horizontal plane at a constant speed relative to the ambient flow. The vehicle may turn in either direction, subject to symmetric constraints on the turn rate and the turn acceleration.(More)
This paper is concerned with the coordinated flight of two autonomous UAVs to be used for aerobiological sampling of biological threat agents above agricultural fields. The periodic sampling task involves two phases: a sampling interval and an initialization interval. During the sampling interval, both vehicles must employ their aerobiological sampling(More)
This paper describes a long-baseline underwater acoustic localization system that was developed to provide three-dimensional position information for the Seaglider underwater vehicle. The accurate inertial position of the glider can be used to estimate performance characteristics and to validate novel motion control and path planning strategies in future(More)
