<R19>
Certain non-VEX components are allowed. Robots are allowed the following additional components from sources other than VEX Robotics:
• Any non-aerosol-based grease or lubricating compound, when used in extreme moderation on surfaces and locations that do NOT contact the playing Field walls, foam Field tiles, Scoring Objects, or other Robots. Grease or lubricant applied directly to V5 Smart Motors or Smart Motor cartridges is prohibited.
• Anti-static compound, when used in extreme moderation (i.e., such that it does not leave residue on Field Elements, Scoring Objects, or other Robots).
• Hot glue when used to secure cable connections.
• An unlimited amount of non-elastic rope/string, no thicker than 1/4” (6.35mm).
• Commercially available items used solely for bundling or wrapping of 2-wire, 3-wire, 4-wire, or V5 Smart Cables, and/or pneumatic tubing are allowed. These items must solely be used for the purposes of cable/tubing protection, organization, or management. This includes but is not limited to electrical tape, cable carrier, cable track, etc. It is up to inspectors to determine whether a component is serving a function beyond protecting and managing cables and tubing.
• Rubber bands no larger than 7.5” long and 0.25” wide.
• Anti-slip drawer liner with similar nominal dimensions to VEX Anti-Slip Mat (275-0120 or 275-0121). The pattern of the matting should be similar to VEX Anti-Slip Mat, and there should be no additional performance gained by using non-VEX anti-slip drawer liner (i.e., no additional elasticity, adhesive backing, etc.). No piece of anti-slip drawer liner can be larger than 12” x 15” and all anti-slip drawer liner must be black in color.
• Plastic zip ties no larger than 12” long and 0.25” wide.
• A Micro SD card installed in the V5 Robot Brain.
• Aerosol-based cooling/freeze spray may be used to assist in cooling motors. Teams using freeze spray or similar products in ways that may reasonably be deemed unsafe could be subject to <S1> Violations.
• Cleaners, disinfectants, and/or sanitizers may be used to assist in cleaning Robots, parts, components, etc.
• See rules <R21> through <R25> for additional legal non-VEX components. This rule is applied differently for VEX U. See Rules <VUR3>, <VUR4>, <VUR7>, <VUR8>, <VUR9>, <VUR12>, <VUR14> & <VUR15>.
