A sports field having automatic line marking capabilities. The sports field includes a robotic total station in communication with a mobile marking robot configured for marking and re-marking of lines on a sports field.

A system is provided for controlling a grain cart relative to a vehicle. The grain cart includes an edge extending between a front edge and a rear edge, and the vehicle includes a side edge extending between a front end and a rear end. The system comprises a ranging device and a controller. The ranging device is configured to determine a position and orientation of the side edge relative to the grain cart. The controller is configured to determine a front distance between the front edge of the grain cart and the side edge, determine a rear distance between the rear edge of the grain cart and the side edge, determine a maximum distance between the front distance and the rear distance, determine whether the maximum distance is greater than a maximum threshold, and if the controller determines that the maximum distance is greater than the maximum threshold, the controller is configured to steer the grain cart to reduce the maximum distance.
