Implementación de un sistema autónomo de fumigación para cultivo de papa mediante el uso de un vehículo aéreo no tripulado.

Abstract

In the present graduation work, the implementation of an autonomous fumigation system for potato crops was developed through the use of an unmanned aerial vehicle. The communication between the fumigation system and the Unmanned Aerial Vehicle (UAV) was based on the Norton methodology, in which nine stages are developed for the sizing, selection and implementation of the devices; In the first stages, the need was identified as well as the collection of information through other previously conducted investigations on similar topics, in the following stages the components were chosen based on the system requirements and the recommendations of the manufacturers of the different electronic devices. The center of gravity and the center of thrust were calculated from the weights and positions of the elements, so that the weight to be equally distributed among the 4 UAV engines. For the assembly of the parts, it was necessary to design clamping couplings between the spraying system and the UAV with the help of SolidWorks Software. The programming of the system was carried out in the Mission Planner Software, calculations of the spray width, speed and height were necessary to provide adequate coverage of the fungicide in the potato plant. The system components were tested individually and together, having as a result a minimum permissible value in the mean of the error, which is why it is concluded that the UAV can carry out the fumigation with adequate fungicide coverage and maintaining communication with the ground control station. Research is recommended so that UAV can perform its functions regardless of weather conditions.
