Maintaining sports stadiums, especially ensuring precise court lines, is laborious. Redrawing lines after events poses a significant challenge for maintenance teams. The proposed bot aims to alleviate this burden by autonomously marking linear lines on sports courts, including those for various sports like volleyball, basketball, tennis, and football, as well as track boundaries. Integrating robotics and computer vision technologies, the system detects court boundaries and existing lines using sensors. Navigation algorithms enable the bot to traverse the court while avoiding obstacles, and a precise line drawing mechanism ensures accurate line placement. Rigorous testing in diverse stadium environments validates the bot's performance and reliability. Implementing this autonomous system into maintenance workflows is expected to substantially reduce manual labor and time spent on line marking tasks, enhancing overall efficiency and effectiveness. This advancement not only benefits maintenance staff but also event organizers. Furthermore, there is potential for additional features and improvements to further enhance the system's capabilities and applicability in various scenarios.
