    At least you should make such things by your self ! No fun to get everything ready made.

    Mr. Avinash ,I appreciate your advice but there is not much time left for the compitition and I also don't know much in electronics beside what we study during first year. So,I have know choice athor than going for the ready made.
    Can you please tell me how many IR-LED and Photodiode pairs will be easy to use ,one with 7 parirs or the one with 8 pairs.

    the number of sensors makes sense in algorithms. If you have not made a line follower with 3-4 sensors, and if you got very little time left, hmmm..

    @vineesh

    :evil: :evil:
    is robocet that great a site that its a shame if you dont visit it??

    and also, any link which doesnot point to the solution directly may be deleted by the mods.

    and its a shame on your part not to give the solution at all, and instead put the shame on the OP.

    grow up, kid!

    2. v tried ldr and didnt follow line
    3. good quality ldr s may work.. dnt knw
    4. TSOP has high sensitivity, that it will detect ir light frm adjacent sensors.
