So... has anyone come to a conclusion on this issue?

It is very clear that the robot must be controlling the compressor when it is filling the tanks - on board or not.

There is a very interesting question regarding switching the battery after the compression is complete. For many robots this is not a real "game changer", but at least one example that's been mentioned on these forums is a robot that requires 7 minutes to compress its tanks!

This is roughly about 40% of the total energy output from the battery in the duration of a match.

Yes, it is legal to store this much energy in springs on the robot, but there is no rule saying that "springs must be stretched/compressed under the control of the ROBOT".

It seems to me that the answer to this question could indeed be a "game changer" in certain circumstances.

When does a robot become the ROBOT?
