Controlador de direção automática para tratores agrícolas

Abstract

This paper presents a hardware and software platform used to implement an automatic steering system for tractors. In the current market there are several systems with this function, but the cost is still high, which makes them inaccessible to many rural producers. This project seeks to elaborate an affordable product that could assist in several activities of the agricultural crop, like planting and harvesting, taking advantage of the GPS already installed on the machines and using low-cost components. The tests performed in rectilinear paths showed that the control system proved to be adequate, being functional for flat terrain and slightly uneven. Even with the tractor not aligned with the route at the beginning of the operation, in a short period the system stabilizes and remains within the configured route. For terrains with greater variations, such as contour plowing, and for non-rectilinear paths, the system response proved to be ineffective, evidencing the need for further improvements.
