Answered: <R15> pneumatics component modification

[Net_Robot]

<R15> Parts may NOT be modified as follows:
a. Motors, extension cords, sensors, controllers, battery packs, reservoirs, solenoids, pistons and
any other electrical component or pneumatics component of the VEX Robotics Design System
may NOT be altered from their original state in ANY way.

On pneumatic cylinders, the back of the cylinder is flat. If the cylinder is mounted in a 1X2X1X?? C-Channel it can only pivit a small amount.
If the back of the cylinder was rounded so the cylinder could pivit when mounted in a 1X2X1X?? C-Channel, would the cylinder be legal? (see drawing)

No, this type of modification is not permitted. The rule you quoted specifically bans modifications of any type to pneumatic cylinders (pistons).
