Abstract
This paper considers path following control for a four-wheel steered
robotic platform. The vehicle used for the experiments is a specially designed
robotic platform for performing autonomous weed control. The robot uses RTK-
DGPS to determine both position and orientation relative to the path. The
deviation of the robot to the desired path is supplied to a high level controller
that determines the setpoints of the wheel angles and wheel speeds. At low level
each wheel angle is controlled by a P controller combined with a Smith predictor.
Results are presented of a preliminary navigation test on a paving.
