Both robots work on the same principle: one motor is on all the time, other motor works only when LDR/Photo-transistor in on white surface. If You post competition track map, we, probably, would be able to tell if these followers are suitable.

I don't see why it shouldn't work. If follower is going clock-wise - place it on the outer edge of black line, if follower is going counter-clock-wise - place it on the inner edge of black line.

I think that IR Emitter/Detector pair is superior to LDR in this application, as it is immune to light other than IR.
