a sportslinemarking robot

Line marking of sports facilities is a manual, time-consuming and resource intensive task!


Why don't we combine the technique of a existing autonomous lawn mower with the prevoius line marking systems ?

It’s common that schools, as well as clubs and municipalities, uses the available pitches for more than one sport, hence changing between soccer, rugby, American football etc. Moreover, rainy conditions let the grass growing fastly on the pitch. This often means doing initial line marking twice or more a week. Combining this with the need for shifting pitches and additional initial markings, as a result of wear and tear, line marking ends up being an extremely time consuming and expensive task that’s in dire need of a new, refreshing and cost-effective solution.
