Abstract: The industry defines precision agriculture as agricultural management which ADAPTS to crop variability.In order to effectively implement precise agriculture，it was necessary to collect data from growing area in an automated manner at a low cost.A flexible and maneuverable small robot was used as precision agricultural implementer to reduce influence on soil compaction in process of movement.By integrating camera with the GPS receiver，a set of basic behavior of a complete coverage of check the crops in the field of autonomous mobile robot，path planner for the field profile and crop types as reference substance to determine the optimal inspection line.Through the experiment，proposed robot changed action required，and proved that method could realize precise operation of crop.
