How much psi is the pneumatics system? I heard 100psi but I also heard the most we could get out of it (at best) is 80 psi. Which one is it?

My understanding is that it is a volume of compressed air @ 100 psi but that the kit includes a regulator that we are required to use that is set to 60 psi.

Yes the regulator is 60 psi maximum, but can be regulated downward. What this means is that if you don't need the full 60 psi to operate your robot mechanisms, you can tune the regulator down and make the air in your tank last longer.

My understanding (from listening to the kickoff) was that the tank would be filled to 100 psi, but that there was a regulator inline that knocked it down to 60 psi for the user.

Does anyone know what the volume and size of the tank is? Is anyone going to use Pneumatics?

i believe its 1.5 gallons at 9 atmospheres...

Does anyone know (ballpark) the weight of the tank? Just from the scratchy webcast it looked like a heavy steel-walled type.

I took the pneumatics seminar at the kickoff. My notes say 1.5 gallons, ~9 atmosphere and ~110 psi.

The SMC representative was very careful to say ~110 psi because of elements beyond their control (such as temperature, humidity, etc.), your milage may vary. However, they were also very diliberate in saying that regardless of the exact pressure, everyone's tank will be pressurized the same, because SMC or FIRST will be filling the tanks at the competitions before each round. FIRST also warned us to make your tanks readily accessable in your design for this reason!
