    Subject: Sandpaper

    Q: Currently, our team is using a sandpaper based gripping surface to hold onto the glyphs. On each of the grippers, the actual gripping surface is a layer of weather stripping covered by a layer of sandpaper. We would like to emphasise that the sandpaper never moves laterally along the glyph, it grips the glyph when the grippers close, and never moves side-to-side st any time, in contact with the glyph or otherwise. It is not set up in a way that the sandpaper would have any chance to abrade the glyph.. Would this be considered legal?
    A: Sandpaper is a product that is specifically designed to abrade and remove material from the surface it is in contact with. It is not possible to guarantee that during a match, as robots move about the field, that the Glyph and the sandpaper will never slide against one another. Therefore, sandpaper is not allowed anywhere it can come into contact with a Glyph, Tile floor, Balancing Stone, or any other Field Element.

        Q: Our team was planning to use skateboard grip tape on part of our robot. We know that sandpaper is illegal, but friction tape is legal. We were wondering if grip tape would also be allowed?

            Q: We understand that Roughtop tread is illegal for drive system components that will contact the playing field floor, but would roughtop tread, specifically Blue Nitrile Roughtop Tread (am-3309), be illegal for use in glyph manipulating components? We've tested it on a harvesting mechanism, and it doesn't seem to harm the glyphs. Thanks!
            A: Yes, Roughtop tread is legal when used in a harvesting mechanism providing it does not damage the Glyphs. Obviously each Robot is different so you may have to demonstrate that the tread does not damage Glyphs during inspection or at the request of a Referee.

                  Q: Post #17 in the Robot Electrical Parts and Materials Rules under Control System Answers said that it is legal to use mirrors. Is there still a restriction on glass mirrors per <RG01>?
                  A: Rule <RG01> does not prevent the use of glass mirrors, however the sharp edges of the glass must be covered or protected per rule <RG01.e>.
