Re: Pre-charing pneumatic air tank

I posted this elsewhere but here goes...

From the Robot Rules Preamble
"In addition, another intent of these rules is to have all energy sources and active actuation systems on the
ROBOT (e.g. batteries, compressors, motors, servos, cylinders, and their controllers) drawn from a
well-defined set of options. This is to ensure that all Teams have access to the same actuation resources,
and to ensure that the Inspectors are able to accurately assess the legality of a given part.
"

Many of the same statements are said of the 12 volt battery. i.e.How bad can it get, it's only 12 volts? 12 volts won't kill you! A small battery can't possibly be an issue, it's not like a car battery?!?! The truth is what you don't know can hurt you in both of these cases. Above all we want to provide information that is both useful and safe for our students. Run the numbers for yourself. What force will a 2" cylinder produce at 60 psi, at 90, at 120 at 150?
