    A: No. Rubber grommets are not permitted under this year's allowed materials rules.

    Possible alternatives within the allowed materials include: electrical tape wrapped around the wires, heat shrink tubing around the wires, or surgical tubing around the wires.

    Default Re: Other Parts and Materials [Heating Lexan and other plastics]

    Thanks.
    A: Heating Lexan and other allowed plastics in order to bend them into another shape is allowed. Heating plastic in the pit area may not be allowed at a tournament. Check with the tournament organizers before using heat guns, or other tools to heat plastic at a tournament.

    A: Yes. That is precisely what we had in mind when writing Rule <R5>d.8. Please re-read that rule so that you can show it during inspection.

    Default Re: Other Parts and Materials - Team Numbers

    We made our numbers out of duct tape (since we're Team Duct Tape) - they meet all three criteria in R10, and we believe meet the spirit and the intent of the rule. We hope FIRST concurs.



    <R10> Robots must display their team number (numerals only, e.g. 106).
    a. The judges, referees, and announcers must be able to easily identify Robots by team number.
    b. Team number must be visible from at least two sides of the Robot (180 degrees apart).
    c. The numerals must each be at least three inches high, at least in 0.5 stroke width and in a contrasting color from their background.
    A: As long as the tape used to make the numbers is not used to connect/tape-together parts, its use as numbers is within the rules.

    A: No. While similar to surgical tubing, Thera-Band tubing is not an allowed material under this seasons rules.
