    Linear Actuators

    Q: Is use of a linear actuator legal in FTC?
    A: Linear Actuators are legal but they must be constructed by the teams themselves. Commercial Off The Shelf (COTS) linear actuators that contain more than one degree of freedom (rotation fo the motor and linear motion of the slide) violates <RM02> which states that "Purchased mechanism kits (for example, grippers) that violate the single degree of freedom rule, either assembled or requiring assembly, are not allowed".

      Tank Treads

      Q: I don't see tank treads on either the legal or illegal parts list. Can my kids use these? We wanted to order the Tetrix Max Tank Tread Kit. Is that legal?


      A: Yes, tank treads are legal but they are still subject to Rule < RG01>.

        Hook on Rope

        Q: If a robot were to use a hook at the end of a rope/string/tether on a pulley mechanism that was used exclusively for latching and deploying, would this be considered detached in violation of <G15>?


        A: No this is not considered detached and is not in violation of rule <G15>. Remember that in designing your bot you may not violate other rules such as <RG08> or <RG01.d>.

          Wedgetop Tread

          Q1: Is Wedgetop Tread (AndyMark Part number am-0522 illegal?
          Q2: Is Green Grippy Tread (am-2611) illegal?
          A1: Yes, Wedgetop tread is legal. However depending on how it is used, the weight of the robot, etc. the Inspectors may still require the bot to pass the test outlined in the Robot Inspector Manual. To summarize, the robot should be placed on top of a field tile and against an immovable surface (wall), the wheels will then be run at full power for 15 seconds. If there is any physical damage to the floor tile, the wheels are not allowed. Discoloration or black marks alone are not considered field damage.

          A2: Yes, the Green Grippy tread is legal but is under the same restrictions as listed in A1.

            Cheesecaking Mechanism

            Q: Are teams allowed to compete while using a mechanism built buy another team?

            For example: Team A has no way of landing and latching. Team B gives them a mechanism to attach to Team A's robot giving them the ability to land and latch
            .
            A: While FIRST encourages teams to help each other improve their robots, using a completed, specially designed mechanism designed and built by another team is not allowed. Cheesecaking, as it is commonly referred to, violates the spirit of the competition as well as rules <RM02> (COTS parts) and <T7> (bringing and using only one robot).

                Team Number

                Q: <RG06>.b states that the team number must be visible from at least two opposite sides of the Robot (180 degrees apart).

                Would having the team numbers back-to-back, for example on opposite sides of a flat board, be legal?
                A: Yes, providing the Team Number is clearly visible to field personnel from two opposite sides.
