Elephant-Human Conflict (EHC) is one of the major problems in most African and Asian countries. As humans continue to utilize natural resources for their own development, the living area of elephants continues to decrease. This leads elephants to invade human living areas and crop-raid more frequently, costing millions of dollars annually. Guardian proposes an autonomous drone system to mitigate crop-raiding. The system is comprised of three parts: a compact low-power GPS tag that is installed on the elephants, a receiver stationed in the human living area that detects the elephants' presence, and an autonomous drone that tracks and herds the elephants away from the area.
