The optical sensors use infrared light to detect where a reflective object is.
Carpet will/should absorb infrared light. The reflective tape, however, will reflect the infrared light back to the optical sensor.
Be careful, where you mount them, because metal is reflective too. The optical sensors might get confused. Also, note that there is a screw on the optical sensor labeled "gain". This tells whether the beam is "wider" (more spread out) or "narrower" (straight ahead). You might want to play with this to determine the optimum configuration.
