Adding to pneumatic piston

Does anyone know if we can mount something to the tip of a pneumatic piston??

Of course you can mount something. Unless its a chain saw or laser of some kind. As long as the material doesn’t break the rules or any of that good junk. It also depends on what its used for and if it would go outside the envelope (i.e. shooter part).

If you are asking if it would be legal to add a threaded part that would allow you to punch the ball towards something, the answer is yes (under the pneumatic section in the robot manual). As long as said device, doesn’t damage the ball or the field and isn’t deemed hazardous by an inspector. Removing a threaded fitting at the end of the actuating arm is not considered modification. This question may have been asked in the Q&A so check there before a final decision.
