Abstract
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. The processor obtains a first measurement of an angle of slope of a portion of piled granular material in a bulk store. In response to the first measurement satisfying a first condition, the robot traverses the portion of piled granular material to incite sediment gravity flow in the portion of piled granular material by disruption of viscosity of the portion of piled granular material through agitation of the portion of piled granular material by auger rotation of the auger-based drive system. The processor obtains a second measurement of the angle of slope of the portion of piled granular material. In response to the second measurement satisfying a second condition, the robot ceases traversal of the portion of piled granular material.
