Localization based on DGPS for Autonomous Robots in Precision Agriculture

In recent years, self-driving systems have smoothly penetrated several sectors, including precision farming. In this context, the Regional Center for Agronomic Research (CRRA) of Settat is working on a project to develop a low-cost autonomous driving tricycle robot for Precision Agriculture (PA). The robot will allow us to perform various tasks, such as data acquisition and the management of operations using a prescription map. The localization of the autonomous robot is a critical part of promoting its use. This paper focuses on the implementation of a Differential Global Positioning System (DGPS) localization system. This low-cost solution is mounted using an Arduino coupled to a GPS module for acquiring localization data that will be served for robot guidance. The experimental results show that our system provides adequate localization accuracy for agricultural robots.
