I wasn’t able to find any specific rule to the amount of pneumatic pistons allowed on a robot. Is there a theoretiacal unlimited amount allowed however the digital ports limit the amount that are usable? Sorry if this sounds like a dumb question.
There is no specific rule limiting the number of pistons on a VRC Robot. However, you are correct that the ports act as a physical limit. There is however one rule that does limit pneumatic usage. Please see below.
No need to apologize. This wasn’t dumb at all.
