<R7>

Certain non-VEX components are allowed. Robots are allowed the following additional “non-VEX” components:
  • Any material strictly used as a color filter or a color marker for a legal sensor, such as the VEX Light Sensor or the VEX V5 Vision Sensor.
  • 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 surface, Triballs, 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, Triballs, or other Robots).
  • Hot glue when used to secure cable connections.
  • An unlimited amount of 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.
  • Non-functional 3D printed license plates, per <R8> and <R9>, are permitted. This includes any supporting structures whose sole purpose is to hold, mount, or display an official license plate.
  • Rubber bands that are identical in length and thickness to those included in the VEX V5 product line (#32, #64 and 117B).
  • Pneumatic components with identical SMC manufacturer part numbers to those listed on the VEX website.

  • Zip ties that are identical in length and thickness to those included in the VEX V5 product line (4” or 11” long).
  • A Micro SD card installed in the V5 Robot Brain.
