• the cart comprising an unmovable receiving element,
• the line marking device comprising:
• either a GNSS receiver or a prism for a robotic total station,
• at least one spray nozzle,
• a comparator adapted to compare a detected location to a predetermined pattern and calculate at least one of a location error and a direction error,
• a prompting device for providing steering information to a user,
