  • Publication number: 20240033918
    Abstract: A piled grain surface management robot comprises an auger-based drive system, a memory, and a processor coupled with the memory. The processor is configured to control movement of the robot via the auger-based drive system. The processor is also configured to direct a traversal of a surface of piled grain in a bulk store, wherein a crust layer of the surface is broken up by auger rotation of the auger-based drive system during the traversal.

  • Publication number: 20230284567
    Abstract: A grain management system includes a robot and a computer system located remotely from one another and configured to wirelessly communicate. The robot comprises an auger-based drive system, a memory, and a processor which controls movement of the robot, via the drive system, relative to grain in a bulk store. During a load-in the robot traverses a landing zone portion, where the grain lands during load-in, of a surface of a pile of the grain to disperse broken grain and foreign material away from the landing zone portion. The dispersal is effected in part by rotation of augers of the drive system. The robot additionally traverses a sloped portion of the pile of grain to incite sediment gravity flow by rotation of the augers. The sediment gravity flow reduces a slope of the sloped portion and further disperses the broken grain and foreign material away from the landing zone portion.

  • Publication number: 20230276739
    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, relative to grain in a grain bin. The processor is further configured to direct performance of a maintenance traversal, by the robot, of a surface of a pile of the grain during a storage period of the grain. The maintenance traversal disperses a layer of the grain on and near the surface and thus hinders crust formation on the surface during the storage period. The dispersal is effected by rotation of augers of the auger-based drive system during the maintenance traversal.

  • Publication number: 20230277990
    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, 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.

  • Publication number: 20230278215
    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, 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.

  • Publication number: 20230068940
    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 relative to a piled granular material in a bulk store, via the auger-based drive system, such that the robot traverses a first surface of the piled granular material in a mapping pattern. The processor is further configured to record a plurality of three-dimensional locations of the robot during the traversal in the mapping pattern. The processor or a computer system coupled with the processor is configured to assemble the plurality of three-dimensional locations of the robot into a three-dimensional surface map of the first surface of the piled granular material.

  • Publication number: 20210276794
    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.

  • Patent number: 9788821
    Abstract: Described are expanded collagenous materials and methods for their preparation and use. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, and recovering the expanded material. Expanded materials can exhibit beneficial persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.
