Looks like a fantastic machine. I can't wait to see this beauty at championship.
I don't have any insider info, but I'd bet Dean Kamen's denim it's their perennially reliable WCD.

Re: Team 254 Presents: Barrage

im really curious as to the purpose of the latch on the cylinders that i assume allow it to open up to catch. why do you need the latch, seems a odd place to put one unless it allows you to make minute adjustments to the shooter compression?

My intial thought is that they're spring release pistons in an effort to save air.

I am going to assume it is because that piston appears to be actuate the backboard of the shooter, probably to assist with catching, so the latch prevents it from moving at all during the shot.

That might be true. I'd also wager it's because of the lever arm between those pistons and the shooter arc plates. Given that they're probably compressing the ball quite a bit, I'd expect without the latch that the pistons would give slightly under the compression load, making the shot less consistent. The latch makes it solid metal holding the load, as opposed to air.

i figured it had to do with ball compression

If you freeze the video with 4.7 s on the auto-clock, you can see 2x 2009 robots, 2x 2008 robots, a small mountain of batteries on the left, and several bumpers in both red and blue on the right.

Amazing.
If 3 seconds isn't enough time for you to appreciate the detail shots of all the beautiful engineering that went into this robot I made an album of them.

I think they must buy/rent it from FIRST because it is accurate down to the FIRST logos and the accidentally power coated corners of the goals.

NASA supports us with official field elements for the use of the three Ames House Teams, as well as local FRC teams, through a pre-ship scrimmage event and the ability to come practice here throughout the year.
