When grains such as wheat and barley are stored long-term in sheds and silos, they’re at increased risk of spoilage from infestation by insects and moulds. CROVER is a robotic device that analyses conditions inside grain bulks to identify sub-optimal storage conditions, as well as physically mix grains in-situ, which helps avoid spoilage. CROVER is remotely operated, with the ability to reach every corner of the grain bulk, meaning workers can avoid performing the risky operation themselves.
