Robot with interchangeable drive system

A robot comprising:

• a body;
• a drive system coupled with the body and comprising one of auger-based surface interface portions and continuous tread surface interface portions, wherein the auger-based surface interface portions and the continuous tread surface interface portions are interchangeable to adapt the robot to one of different operating conditions and different uses;
• a memory coupled with the body;
• and
• a processor coupled with the memory and configured to:
• in response to the drive system being configured with the auger-based surface interface portions:
• control movement of the robot, via the drive system, to traverse about atop a first surface, wherein the first surface is a surface of a piled granular material in a bulk store;
• obtain a first measurement of an angle of slope of a portion of the surface of the piled granular material;
• responsive to the first measurement satisfying a first condition, direct the robot to traverse about atop the surface of the portion of the piled granular material to incite sediment gravity flow in the portion of the piled granular material by disruption of viscosity of the portion of the piled granular material through agitation of the portion of the piled granular material by the traversal;
• obtain a second measurement of the angle of slope of the portion of the piled granular material;
• and
• responsive to the second measurement satisfying a second condition, direct the robot to cease the traversal of the portion of the piled granular material;
• and
• in response to the drive system being configured with the continuous tread surface interface portions, control movement of the robot via the drive system to traverse across a second surface, wherein the second surface is one of a solid and a semi-solid surface other than the surface of the piled granular material.
