The R.A.T'S copter is the drone used in the Rodent Autonomous Terminator System. This is a quad copter based Autonomous UAV (Unmanned Aerial Vehicle) built out of aluminium. It features powerful brushless motors, telemetry and a robotic hand which holds payloads to be released.

Once the R.A.T'S tunnels detects rodent presence, the ground station will program the GPS location of the detected activity into the copter. The copter then autonomously flys above any obstacles like trees and drops a payload of poison which will only affect the pest's location, minimizing the harm to innocent animals.
