3065: Broken Rubber Bands
<R19> Modifications of parts. Parts may NOT be modified unless specifically listed as an exception in this rule. Examples of illegal modifications include, but are not limited to, bending, cutting, sanding, gluing, lubricating, taping, and melting. The following exceptions are the only legal modifications of parts: Cutting metal VEX IQ or VEX V5 shafts to custom lengths. Bending parts which are intended to be flexible, such as string, rubber bands, or thin plastic sheets. Cutting VEX IQ pneumatic tubing to custom lengths. Tying knots to shorten or connect string or rubber bands.(https://events.vex.com/storage/game_manual/VEX_IQ_Robotics_Competition_2025-2026_Mix_Match/rules/R19.html)
My understanding is that broken or cut rubber bands can not be used in Vex IQ, however some argue that per R19 "Tying knots to shorten or connect string or rubber bands" means if you have a broken rubber band (you didn't cut it, which would break this rule) you can tie a knot to connect it again making it a legal part once again.
As an event partner, I would really like clarification on that last sentence in R19 so our refs have a definitive answer in the Q&A or a Rule update we can point to and say yes or no on whether broken and tied rubber bands are allowed.
A Team should not be penalized if a rubber band on their Robot breaks during a Match. However, they should replace any/all broken rubber bands before their next Match. A broken rubber band is not a legal Robot part, even if it's tied in a knot.
