Cheers erco, yeah, a line with ac under the carpet to not re-invent the wheel maybe interesting. I posted a vid of my robot to texas then modded the code...yet again and bingo..the one that works as planned. Not a fluke.consistent.Am well chuffed with it. Still awaiting Sharp sensors and got to make an octopus tracker with the oled project.
I might make a line follower with a simple algo and sensor/s to see just what's so difficult. Can 3d printers do transparent plastic?
