A Five-Step procedure is proposed to be used in weed control programs based on the use of a robot fleet. The five steps are: 1) field inspection, 2) longterm decisions, 3) current year decisions, 4) unit distribution & path planning, and 5) online decisions. Monitoring weed populations at various times could be achieved using unmanned aerial vehicles (UAV) equipped with cameras and GPS. A long-term decision module could be used to optimize the choice of crop and herbicide rotations as well as the tillage system. A computerized system should quickly query databases containing information about the weeds present in each field and the herbicides available to control them, performing calculations to determine the cost effectiveness of each option. The system should generate a georeferenced prescription map indicating the sites were each herbicide should be sprayed. This map should provide the information required to decide the optimal distribution of the spraying units of the fleet and their corresponding navigation plans. Final spraying decisions should be based on both, prescription maps and online information coming from sensors located in the sprayer.
