Abstract

The present invention features an intelligent sprinkler irrigation system for delivering fluid to an arbitrarily-shaped area in a precise manner. In general, the system comprises (a) a fluid source comprising a pressurized fluid; (b) at least one programmable sprinkler head fluidly connected to the fluid source; and (c) a computer system configured to control the sprinkler head to precisely deliver fluid according to a pre-determined sprinkler function. The computer system comprises a teach mode, wherein a plurality of drive parameters are learned and recorded. These drive parameters function to dictate the specific vector positioning of the sprinkler head during execution of the sprinkler component. The teach mode is further configured to learn and record a plurality of flow parameters, which function to control the fluid delivery component of the sprinkler head (e.g., the valve or nozzle), and more particularly, the manner in which the fluid is delivered or emitted from this component.
