I have seen the GPS robot that paints fields. The video I watched was on some manicured soccer field. I struggle to see how this thing will perform on our field late in November in Northern Indiana. Whether, divots, mud, etc.
Really cool technology, but not practical where I am at, even if the price was right.
I make suggest you check in with Noblesville High School later this fall and see how they like their robot? Grand Park in Westview has two and a soccer club in Fishers has some very interesting terratin and they love it! Our robot is specifically designed to handle issues with fields late in the year as wear and tear and soggy conditions can take a toll. The two rear wheels operate independently with their own drive motors, helping each other out on field variations, keeping the lines straight.
