This work represents a step towards reaching a fully automated agricultural robot, replacing the current existing methods of path finding for an algorithm centered at a variant of the PEARL method for energy based multi-model fitting. The method has also been allied with a filter for it's results and a data-filter that eliminates points that are too far to be considered part of the model. Other sensors were combined with the LiDAR readings in order to increase the program's reliability and allow control in scenarios such as the row-change, where there are no readings provided by the optical sensor. The results are encouraging and were compared against other methods, having better performance than those.
