I have a question I want do my Project, it will be a small automatic mower, but at first I start with the attitude. I want to build a vehicle that will be able to remember the route travelled and do not repeat.
I do not want that the vehicle have a terrain (square) and randomly bounce off the wall to the wall and drive randomly.
only to cover the entire area without harming the movement or at least minimise it.
it'd be great if it was a three-way trip on the dock, avoiding obstacles and making circles to reduce the surface area of the square to zero.
How to approach this? The best method is with gps? Or maybe ultrasonic sensors and a compass?
