Per the VRC Game Manual, there are three types of pneumatic components permitted in the VEX Robotics Competition:
- The official V5 Pneumatics Kit (released in 2023), manufactured by and purchased from VEX
- Legacy (pre-2023) components purchased directly from VEX
- SMC components that are equivalent to the legacy VEX components, but manufactured by and purchased from SMC (or an SMC reseller)
This article is intended to be a visual inspection reference that will help clear up any confusion regarding differences in part numbers or appearance. The parts below are the ONLY pneumatic components that are VRC legal; parts which look similar to a legal part in all ways except color or material are prohibited.
Note: This article replaces the “Legal Pneumatic Parts” PDF document that was used previously (prior to the 2023 season), and is considered an official reference for competition legality.
V5 Pneumatics Kit
Notes:
- There are no SMC equivalents for parts found in the V5 Pneumatics Kit.
- The V5 Pneumatics Kit and legacy/SMC parts are compatible; using parts of both types on the same robot is legal, provided no other rules are violated.
- See this article from the VEX Library for more information about each component, including a diagram of one possible configuration.
