That would have been a great second pick at almost any PNW district.

I'd argue first pick.

That's actually quite good. The shooter appears to be faster than 254's was.
Are the intake wheels the same ones you used this year?

Yeah, if that robot didnt play the exact same role as our robot it would be very appealing for a first pick.

Re: Tem 973 Pruhzents: SKYSTALKER-ER
 
Maybe I'm just not seeing it, but what causes the ball to be pushed up and out the shooter? Is it the action of the intake folding in all the way that causes this, or is there a separate mechanism to push it upward when it's time to shoot?

Didn't almost every robot play the same role (more or less)?

Finisher vs. Trusser vs. Inbounder, etc.

This is pretty clearly built to be a finisher, like 254 was for the most part.

It's funny because I remember one of their mentors saying they designed to be the middle player (like they did at Waterloo), but they ended up being the best finisher in the world.

I'm really proud of the 973 crew for making this robot work so well. The robot was made in about two shop days total, and I feel is within the skill set of most FRC teams.

More details will follow later.

There's a small wheel on the back (vertical) section, right about in the middle. If that isn't a "kick" device and/or shooting wheel, I'm not sure what it is... particularly with those Colsons sitting right behind the front frame looking suspiciously like a shooter.

Yup, it actually works with just the intake too. With some geometry tweaking it'd work pretty darn well with out the rear wheel, but currently there is too much compression in the intake portion so the rear wheel is a cheap band aid.

This whole robot was an exercise in prototyping primarily, the fact that we get to compete with two of them at one of the most competitive offseason events is just a bonus.

I've been wondering for a while...

What is up with 973's intake wheels?
Are those lego mindstorm wheels??

How do you make your hubs?

So does this offseason event revive the game from 1 year ago? Seeing as the event is holding the 2014 game in a 2015 offseason event. Or did the event coordinator decide they didn't like recycle rush so they went back to Aerial Assist?

Yes. They surveyed teams in the area and found enough were willing to play 2014.

Yep, they decided to plate Aerial Assist instead of the current game after checking with teams to make sure they would get enough entries.

Re: Tem 973 Pruhzents: SKYSTALKER-ER
 
That'll make an excellent finisher for sure

Have a quick look at your shot angles and speeds. If your shot accuracy is reasonable, there is one combination that will let you shoot from against the low goal (as shown), or from ~30" out from the low goal (one robot width). That last shot can be *really* useful against in a pushing match against defense!

Any tricks on assembling? The ones we used last year on one of our intakes just took forever.

The fact that that robot actually works better then anything my team has ever built is kinda sad.

They do take awhile, but if you assemble then right the first time, they generally don't open up over use. Quality of hubs certainly affects this. We've only had issues with wheels when they weren't initially assembled correctly.

If you've done it once or twice and have the right tool, it only takes 2-3 minutes and it will never slip. We ran crazy torque on them in 2011 and 2014 and only ones that were assembled with the bead clearly popping out ever slipped.

The tires are 1.9 and 2.2 Chisels from Proline, on Axial 1.9 and 2.2 8 Hole beadlock hubs. We directly hex broach the axial hubs (which yes, unfortunately means you have to buy new hubs each year for comp bot for an essentially COTS part).

Those look about like the hubs we used (Brando brought 'em in to try)

Guess it's just a practice thing, I remember it getting easier over time but it still seemed to be a pain. Better lighting might have helped.

Very nice! It looks (and performs?) frighteningly like a simplified 254 robot... Just shows how much good design can get you, even if 'build quality' isn't the finest.

After looking at that robot a little more it occurred to me that there must be some complex math driving the angle of that curved back. I was woundering if someone might be able to outline that for me.

Intake portion is a 25" radius, then there is ~9" of straight vertical, then the shooter is 23" radius.

Not complicated at all ;)

Could be laid out by hand easily w/ some straight edges, some string and a marker.

Can you post some documentation about the process of building this? I think this would shed some light on the prototyping process of the best of teams.
