Well Ben, basicly when you don't know, you don't know.. that's why I'm here, to learn and make sure that I'm investing my money in the right place.
I just mentioned 3pi because I saw a of a lot of online videos and it's incredible accurate! There are too many robots availables, but the way they interact with the lines it's most of the times like bouncing side by side, not consistent at all, when yours take the road pretty much as a train on track. (Just trying to put some "sense" to my first statement).
Reading about orangutan it seams to be very promising! but..
How to put it all togeather with the sensors?
And where to get the source code when you are not a programmer..?
If you've got a good answer to make it happen, then you made a combo sale.
Thanks for your interest.
