Andrew Davis was allowed to use his unmanned aerial vehicle to sprinkle weeds in Tasmania. The drone is operated only in areas perilious for people or unreachable for the helicopter.

Initially, the drone observes and photographs the terrain, and then he makes a decision regarding places that should be sprinkled. He finds support in his mother who helps him to tackle the problem.

Andrew also reflects on the possibility of deploying of drone swarm which simplifies the task and allows to spray rapidly.
