If you are really saying "there is no minimum PSI limit" and that literally any change in air pressure constitutes a pneumatic device, then this would apply to any fan (including those integral to motors / speed controllers), spoked wheel (flywheel shooters move a LOT of air around), etc. Such an absolutist position is just ridiculous.

If the whole robot drives into a tube with a flap at the other end, it would, for a split second increase the air pressure in the tube.
So is the whole robot a pneumatic device?
