"Build me a robot so I never
have to go into a grain bin again!"

The Grain Weevil - impacting the quality of stored grain and farmer well-being
by controlling risks, controlling costs, and removing the farmer from the bin.

Advanced Grain Bin Management Benefits

The Grain Weevil is a grain bin safety and management robot that directly engages the surface of the grain. Grain bins are dirty, dangerous workplaces. We keep that farmer with a shovel out of the bin by leveling, breaking crusts, doing inspections and feeding grain into the extraction augers.
