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 grain bin. The processor is further configured to direct traversal, by the robot, of a landing zone portion of a surface of a pile of the grain during load-in of the grain to disperse broken grain and foreign material away from the landing zone portion. The landing zone portion is located in a center of the grain bin where the grain lands as it is augured into the grain bin during load-in. The dispersal is affected in part by rotation of augers of the auger-based drive system.
