One of our challenges is to drive around in passive greenhouses on soil/dirt paths. These paths are messy so it can be quite tricky, but we're always very proud to see that we can keep ourselves centered.
The red line is the detected center of row, and the yellow line indicates the center of the robot body (bottom point) and the angle to correct in order to reach the center of the path.
