  • Video Camera on a Robot

    Originally posted by FTC4311
    In a tournament last week, one of the teams mounted a video camera as a "decorative item". It seems that violates the rule of no external batteries (or possibly IR sources) (assuming it was powered), which is why our team had taken our keychain camera off our robot, but it is a neat idea and gives great shots (we have used it in practice). Can we do this in future tournaments?
    You are correct, an onboard camera would violate the stored energy rule specified in <R17>. The GDC is also concerned about possible interference from the camera's built-in WiFi, Bluetooth, and IR rangefinder. Therefore, cameras are not permitted on the robot.

    • Teflon Tape

      Are teams allowed to use Teflon tape on their robots? As long as the 24" dimension constraint was not exceeded, Teflon tape would satisfy all of the constraints specified in Rule <R5> C-1.
      Teflon is an allowed material in rule <R5>c.1. Teflon tape is permitted if it isn't adhesive backed and the material satisfies the size constraints specified in rule <R5>c.1.

      • Shoulder Screw

        Originally posted by FTC3785
        According to R5.c.18. "All mechanical fasteners (nuts, bolts, screws, etc.) of any length, any thread type, up to 0.375” (0.9525cm) diameter may be used." Just checking, so McMaster Carr item # 91259A544 Alloy Steel Shoulder Screw, 1/4" Shoulder Diameter, 1-1/4" L Shoulder, 10-24 Thread is allowed?
        Please read the Q&A forum prior to posting questions. This question was addressed in the Robot Parts and Materials section of the forum on 12-12-2011 in post #78. Shoulder Screws are allowed provided that they satisfy the constraints listed in rule <R5>c.18 and no other rules are violated.

        • A Question About VELCRO

          Originally posted by FTC3785
          The manual states "The (VELCRO) fastener may not be used as tape (i.e. the adhesive side may not be used to join together Robot parts)." Can I assume that the hook and loop sides can be used to hold two arms to each other. For example, we might want to squeeze two arms together at some point and use the VELCRO to keep the arms together. This seems to be a permitted use of VELCRO. Correct?
          Yes, the VELCRO hook and loop sides joined together to secure robot parts is permitted by the rules.

          • Fastener Thread Type

            Originally posted by FTC3550
            Rule <R5> C 18 first states that teams may use fasteners of any length, thread type, and must be under 0.375" in diameter. It then goes on to state that "compatible fasteners are characterized bu using the same thread characteristics as TETRIX fasteners."

            Q1: May the fasteners have any tread type and the rule was stating TETRIX compatible fasteners, or must teams use fasteners of similar thread type to TETRIX fasteners?

            Q2: Also, I would assume that said fasteners could be modified, but could you please clarify on the limitations to modifying these fasteners?
            A1: This question was addressed in the Robot Parts and Materials thread on 09-30-2011 in post #7.

            A2: There are no rules specifically addressing modification of fasteners.

            • Lead Screw flange Nuts

              A: Yes, a lead screw with an integral mounting flange is a legal component.

                • Nylon Lock Nuts

                  Originally posted by FTC4081
                  We ordered the following thinking they were nylon-insert lock nuts, but they are lock nuts completely made out of nylon ( McMaster # 94909A159 - Nylon Hex Locknut, self-threading, 6-32 thread size, 5/16" W, 13/64" H ) Would this part be allowed or should we order new? Thanks.
                  This is an allowed part based on the following posts to the Parts and Materials Q&A:

                    Q: Are there any restrictions on allowable materials for washers? Can nylon washers be used?
                    A: There are no restrictions on washer materials. See the Parts & Materials post #128 on 02/16/2012 for guidance concerning the difference between washers and spacers.

                    • On-Board Camera?

                      Originally posted by FTC5257
                      Would it be legal to have a small camera on the robot for the sole purpose of recording the match from the robots perspective for footage to use in marketing material, team videos, etc, similar to how it is done in FRC?


                      A: No. The camera does have a battery which is a violation the stored energy rule specified in <RG10>. The GDC is also concerned about possible interference from the camera's built-in WiFi, Bluetooth, and IR rangefinder (if present). Therefore, cameras are not permitted on the robot.
