Crover’s robotic solution is the world’s first subterranean drone. Capable of swimming through grains, oilseeds and protein crops in bulk storage, the robot monitors the presence of moisture and pests, helping farmers and grain merchants to avoid substantial losses.

A start-up from the University of Edinburgh, Crover won Converge’s KickStart Challenge prize in 2018, and reached the finals of the Converge programme in 2019.
