    Yes it does - that's what we used for the line following competitions at Expo 2012 in our back parking lot - the tape is still there like we laid it yesterday.

    I thought you used aluminum foil tape... like http://www.amazon.com/gp/product/B000HBOYZO/ref=pd_lpo_k2_dp_sr_3/179-0767128-8112843?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=lpo-top-stripe-1&pf_rd_r=07P63EF8V3XH7R2X42JB&pf_rd_t=201&pf_rd_p=486539851&pf_rd_i=B007A5ZIE6

    That might be be shinier & flatter, but the Duck tape is cloth-based and can be torn easily into strips. This cheapskate can get 3 strips out of the 2" wide roll. :)

    I layed the roll on its side and used a strip of 3/4" wood as a guide for my razor knife as I carefully turned the roll against the knife, that made for three nice shiny rolls of line following fun..

    Not me!, I remember the whole thing very clearly...
    Having some experience with the shiny tape, I know it sticks well to any dry surface, especially to a porus surface.
    So, I was trying to stop Mr.harris, but I was quickly subjugated during a short scuffle for the tape.
    I would have gained control of the tape too, except for erco stepping in to break it up with his FlameBot.
    I was forced to relent the tape, And now the rest is history...

    At least, I'm pretty sure thats the way it happened, Things got a little foggy with a blast of burning hair spray to the face...:coffee:

    OK, Expo will be here before we know it. Time for some SERIOUS answers about last year's LFO.

    Nobody actually completed it?

    Is it the chrome fabric DUCK tape I mentioned here (that MattG says here) or the aluminum foil tape decreed here: http://www.parallax.com/tabid/969/Default.aspx

    Is it 1" wide, as decreed at that site, or 3/4" as Tommy said here? Yes, little details like this do matter.

    Seems like people struggled a lot last year just detecting the line. The "asphalt" was fairly white and reflective. It was either pouring rain or blinding sun. Did we learn anything? Will anything change?

    Is Daniel Harris the only contender? What did he use? Is there any video from last year? Did he actually use 38 kHz IR sensors? Seems nutty.

    I may just field an entry if I get some accurate answers soon.

    Yeah, you're right on the tape erco . The stuff we used for competition was foil tape -kinda like aluminum foil with adhesive on one side.

    As far as standards for the coming Expo, we should publish those at least 60 days in advance prior to competition date, which would allow for more entries, and maybe a beginner's and advanced courses.

    Since both of you (erco and Tommy) are so embroiled in making the upcoming Expo a massively-exciting event,
    I do hereby appoint both of you as "co-chairmen of the line following robot competitions" :tongue:

    Gentlemen, work out the details, and have a report on my desk by 9am.
