A method of creating a stand-off between insulation and chime on a storage tank is provided. A plurality of tank chime spacers are positioned in space relation to each other such that the bottom of the tank chime spacer is positioned on the tank chime and one of the peripheral side walls of the tank chime spacer is positioned adjacent to the sidewalls of the storage tank to create a gap between the tank chime and the sidewalls of the storage tank. Each of the tank chime spacers has a body with a top, a bottom and peripheral side walls.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot, via the auger-based drive system, relative to grain in a flat storage bulk store. The processor is further configured to direct traversal, by the robot, of a portion of a pile of the grain in the flat storage bulk store. The traversal is performed to incite sediment gravity flow in the portion of pile of grain system to walk-down the grain in the portion. The sediment gravity flow is incited by disruption of viscosity of the portion of the pile of grain through agitation of the portion of the pile of grain by auger rotation of the auger-based drive.
