WHICH ONE WOULD YOU SUGGEST E TO USE THE FIRST ONE(REFLECTIVE SENSOR) OR THE SECOND ONE(LDR)
AND ARE THEY GOOD WITH 90 DEGREE TURNS AND ARE THEY GOOD FOR COMPETITIONS.

newInRobotics:
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.

sohailsameja:
this is the track.

newInRobotics:
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.
