How accurate can a line following robot be? (Laser cutter idea inside)
I have no idea how accurate line following robots can be (and this is what I'd some clarification for), but could a cutting laser be mounted to one? The robot would just follow a black line that you've printed out, and in the process would have also cut out the pattern. If that would work, this would allow you to cut out shapes from a huge canvas size, as well as making quick stencils with a fine line Sharpie.
