Thanks for the thoughts.
I'm not sure if it's been done before, but I'm now making a playing field where the bot will have to
keep within two black lines using 2 RCX light sensors to see how it compares to conventional line
following. I'll include a T-junction to see how the bot will react in actual practice.
Nothing like trying it out to see if it'll work.
