Hong Kong’s sports fields run on tight schedules, just like any major city around the world. That’s where autonomous line marking brings real efficiency. With industrial-grade RTK, every line is placed with centimetre accuracy even in dense urban areas. A handheld point-marker builds maps in minutes, without moving the robot across different sites. AI-driven marking saves over 90 percent in labour and cuts paint use by more than half. One charge covers a full 11v11 football pitch, and quick battery swaps keep the robot running all day. Precision, speed and consistency. This is modern line marking for a fast-moving city.
