Pneumatic shooter? Why so many dry fire noises?

Its not dry firing they are pre-loading their cylinders to aid in firing farther and faster

We've done pre-loading before, too, and I thought it could be what was going on, but it doesn't sound right rhythmically in the video. :\

Sounds like a revolver style shooter to me! Some teams had a similar setup in 2006 (See Picture Below). Awesome shooter High Rollers!

Had a similar idea in mind too, assuming its the pneumatic kicker from your 2010 bot (http://www.youtube.com/watch?v=raZdkGxq5Ig) with a cylinder of some sort to direct the angle.
Only problem is that you'll hafta be at the same exact spot to get it in every time. Otherwise it's a great idea for a consistent angle and distance for 3 consecutive kicks.

This is definitely not a flywheel shooter - you'd hear the woosh. Sounds like a precharged pneumatic piston is propelling the balls. A very consistent and very good idea.

I suspect it is something like this http://www.youtube.com/watch?v=t0o-y..._order&list=UL just with a different angle and a stronger pneumatic. Or it is something similar to this with surgical tubing power and a pneumatic to retract it for the prototype and a winch on the actual bot.

Piston? Chris you're better than that

[JB987]

Amazing what you can do with a little bit of air... or a lot.
