Drone Deployable Automated Pellet Dispensing System

Black-footed ferrets have become one of the most endangered animals in North America due to the emergence of the sylvatic plague, a flea-borne bacterial disease of wild rodents. To mitigate the loss of this species, a sylvatic plague vaccine (SPV) has been developed in combination with a peanut butter bait for oral administration to wildlife. Current administration routes for SPV baits include hand delivery, off-road vehicles, or unmanned aircraft systems equipped with a hopper. However, these delivery means are time consuming, effort intensive, frequently jam, and may not be viable in restricted areas. Further, hand delivery and off-road vehicles are potentially more destructive to soils and vegetation.  

 

Researchers at Arizona State University have developed an efficient drone deployable payload mechanism designed for automated dispensing of vaccine-pellets in a metered fashion. This system also includes an anti-jamming mechanism for a more robust operation. Integrated with a flight controller, the system is preprogrammed to precisely deploy multiple pellets from the UAS in a manner that provides for uniformity, increased coverage, and optimized flight operation. Because this utilizes drone technology, there are minimal disturbances to the habitat and increased accessibility to difficult to reach areas. While initially developed for vaccine pellets, this system could be used to deploy other payloads that support conservation.

 

This technology provides a low-cost, robust and efficient system to deploy pellets for a multitude of wildlife and nature conservation applications with minimal habitat disturbance.
