Answered: Painting and Anodizing Robots

Dear vex-

As i have been thinking of ways to make my robot different from other robots i have a couple questions that i would like to know as for what I can and Can not do to my robot. Is it legal to paint the metal pieces? And what about anodizing the Aluminum pieces, as anodizing doesn’t change any of the physical properties of the metal. Thanks for your help. Worlds turned out great this year!

Let’s take a look at the applicable rule in the VEX Gateway Game Manual

Thus, you may paint your robot, as long as it is totally “non-functional”. If any painted piece interacts with a Scoring Object it would be considered functional and not allowed.

Anodizing does change the physical properties of the metal, by making it harder (among other things). This is a chemical change which would not be allowed.
