Family farming is an important generator of employment, income and food for the country, despite having a smaller area for its development, family farming has an important participation in national agricultural production and, the high cost of the agricultural mechanization, these farmers excluded from the agricultural mechanization process. Faced with such exclusion, use the evolution of technology systems most widely applied, such as Robotics, can meet effectively the needs for labor of farmers, and the trend is that the various sectors of agriculture which today are held by conventional way, be replaced by standalone devices. The objective of this work is to develop a robotic device (RIRRIG), able to interact in a three-dimensional plane, with a system of actuators, sensors and controllers in order to carry out irrigation in greenhouses. Provided with computer intelligence, the robot performs individual irrigation of plants in greenhouses, based on the reference evapotranspiration, leading to the terminal plant tool, which in turn, applies in each pot a given blade. Made the field data collection and analyzing the data, it was found that there was no statistical difference between means for manual irrigation and robotics in the development of agronomic variables of stem height, stem diameter and number of leaves, it being possible It is concluded that the robotic irrigation promoted a lower coefficient of variation and a lower standard deviation in the samples. It is important the fact that robotics when applied to agriculture, it is presented as an option to complement or manpower replacement for agricultural management, as it requires minimum operator intervention for operation, thereby depriving workers of activities stressful, repetitive and risky to health. It is important to highlight its importance in the rationalization of water resources to apply only the amount of water required by the plant and as technological innovation applied to the Brazilian semiarid region.
