The following rules are highly controversial and need to be changed or removed.

Rule Sg2

Horizontal expansion is limited. Once the Match begins, Robots may expand

horizontally beyond the 18” x 18” starting size limit within the following criteria: a. No horizontal dimension may exceed 22” (558.8 mm) at any point during the Match.

b. This limit refers to the horizontal distance measured between any two points of the Robot, including diagonals, relative to the playing Field (i.e., it does not rotate with the Robot).

Rule R19k

k. 3D printed Robot parts for any purpose, including non-functional decorations and license plates. Copyright 2025, VEX Robotics Inc.

Rule R25

A limited amount of custom plastic is allowed. Robots may use custom-made pieces cut from certain types of non-shattering plastic, up to 0.070” thick.

a. Each Robot is limited to a maximum of 12 individual pieces cut from non-shattering plastic. This includes non-shattering plastic used in non-functional decorations.

b. Each individual piece of non-shattering plastic cannot be larger than 4” x 8” x 0.070”. c. Teams must present and display ALL non-shattering plastic parts during inspection. i.

Inspectors will verify the total number of plastic pieces. They may use dry-erase markers or other forms or temporary marking to aid in counting.

ii. Inspectors will verify that no non-shattering piece exceeds the size limitation.

d. Plastic may be mechanically altered by cutting, drilling, bending, etc. It cannot be chemically treated, melted, or cast. Heating polycarbonate to aid in bending is acceptable.

e. Legal plastic types are polycarbonate (Lexan), acetal monopolymer (Delrin), acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, PTFE, and FEP.

f. Shattering plastic, such as PMMA (also called Plexiglass, Acrylic, or Perspex), is prohibited.

g. Plastic sheets sold by VEX are considered “plastic” in the context of this rule, and are subject to the same limitations as “off-the-shelf” plastic sheets. Examples include the 276-8340 PET sheets, and the 217-6626 / 217-6627 polycarbonate sheets.

h. This rule does not apply to 3D printed plastic parts. 3D printed parts are not permitted in the VEX V5 Robotics Competition for any purpose, including non-functional decorations.

Note: Teams are strongly encouraged to provide inspectors with 1:1 scale drawings, identical spares, or 1:1 scale tracings of their non-shattering plastic pieces to aid in inspection. Drawings and tracings should accurately reflect ALL shapes and dimensions of each piece.
