**AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** HE NOTION OF REPLACING ONE LARGE PIECE OF AGRICULTURAL EQUIPMENT WITH MULTIPLE SMALL AUTONOMOUS UNMANNED GROUND VEHICLES (UGVS) IS GAINING MOMENTUM IN DISCUSSIONS ACROSS RESEARCH AND INDUSTRY GROUPS. THIS NOTION IS PROMISING IN SMALL ACREAGES, WHICH ARE CHARACTERISTIC OF SPECIALTY CROPS AND ORCHARDS, HOWEVER, FOR MIDWESTERN ROW-CROP PRODUCTION SETTINGS, WHERE FIELD SIZES ARE LARGE, AND TIME WINDOWS FOR FINISHING THE TASKS ARE SHORT, MANY CHALLENGES EXIST TO FULLY REALIZE THIS CONCEPT. ONE OF THE IMPORTANT CHALLENGES IN USING MULTIPLE SMALL UGVS THAT REQUIRE INNOVATION AND ATTENTION IS THE ABILITY TO AUTOMATICALLY HANDLE CROP INPUT MATERIAL SUCH AS SEEDS, CHEMICALS, AND FERTILIZERS WITHIN THE FIELD. THE FULL POTENTIAL OF A MULTI-ROBOT SYSTEMS CONSISTING OF MULTIPLE SMALL UGVS CAN ONLY BE REALIZED IF A PRACTICAL AND ROBUST MATERIAL REFILLING STRATEGY IS DEVISED. A MORE EFFICIENT APPROACH COULD INVOLVE THE ABILITY TO REFILL THE TANKS OF THE SMALL ROBOTIC PLANTERS WITHOUT THE NEED FOR THEPLANTING ROBOT TO LEAVE THE PLANTING LOCATIONS IN THE FIELD. WE PROPOSE A NOVEL APPROACH FOR MATERIAL REFILLING OF UGV SEED TANKS WITH UAVS BY DEVELOPING AN AUTOMATIC MATERIAL REFILL SYSTEM FRAMEWORK CALLED U2AGV-REFILL. WE HYPOTHESIZE THAT THE ABILITY TO REFILL THE TANKS OF SMALL UGVS IN THE FIELD AS OPPOSED TO REFILLING AT THE FIELD EDGE, WILL OFFER SIGNIFICANT ADVANTAGES TOWARDS IMPROVED FIELD EFFICIENCIES AND CAPACITIES OF ROBOTIC PLANTING. U2AGV-REFILL SYSTEM WILL ADDRESS IMPORTANT KNOWLEDGE GAPS IN THE AREA OF UGV-UAV COLLABORATIVE STRATEGIES FOR AUTOMATIC MATERIAL REFILL IN ROW-CROP PRODUCTION SYSTEMS.
