"Compressed Air" vs. "High Pressure Blower"

[Jeff Pahl]

I inspected a large number of fan/blower robots during Lunacy, and I agree that the use of a fan or blower in those applications was not "pneumatics". The air was free flowing in those applications.

The deciding point for me is when the air becomes contained somewhere in the system at an increased pressure, be it in an accumulator, shooter barrel, etc. Does the ball just fall into a free-flowing air stream, or is it constrained in a barrel with the blower building pressure behind it? There's a difference between the two. Just too many questions at this point.

I love the idea, and would be very impressed to see it well implemented on a robot. I don't think I could make a call on "legality" without actually seeing a specific implementation.....
