See you in Calgary and in Sydney Regionals
Good luck to all teams

Turret!!!!! This robot looks awesome!

Re: Australian 4613 Robot Reveal 2016!!
 

First of all, your field looks amazing! Secondly, very impressive robot. Most of the teams I've seen have had lots of issues aligning correctly with the goal. Your bot seemed to have a consistent shooter from what I saw. I can honestly say, you changed my opinion of the 6 wheel pneumatic drive. Great robot. Good luck in this season.

Re: Australian 4613 Robot Reveal 2016!!
 

Maybe your opinions are correct. Check at 0:28 and recount the wheels :) :)

Re: Australian 4613 Robot Reveal 2016!!
 

You'd be surprised how well 6 wheel pneumatic works. We've got almost the same robot aside from the turret part.

Re: Australian 4613 Robot Reveal 2016!!
 

Really solid robot from one of the newest #TeamIFI members!

The sideways shot from the back is a neat wrinkle in strategy.

Hope to see you at champs!

Re: Australian 4613 Robot Reveal 2016!!
 

Wait... 7 wheels? or is there another one in the center that I couldn't see? I take it that extra wheel is for the cheval de fries?

Re: Australian 4613 Robot Reveal 2016!!
 

Nah, keep looking. There are a few more than that :)

Re: Australian 4613 Robot Reveal 2016!!
 

Geez... is that 10? are all of those wheels for the drive system? either way, that is a powerful drive system.

Re: Australian 4613 Robot Reveal 2016!!
 

Awesome. I was blown away. Good luck this season. This is my favorite robot so far:)

Re: Australian 4613 Robot Reveal 2016!!
 

Very nice Barker College! Jeser, Daiane and your awesome Aussie crew! Another fantastic bot.

Re: Australian 4613 Robot Reveal 2016!!
 

Looks Great!
It was a pleasure to work with 4613 on Curie last year, I look forward to seeing them at Champs.

Am I missing something? What did they do to show that their shooter is consistent?

Re: Australian 4613 Robot Reveal 2016!!
 

Corndogs for you. There are 6 pneumatic wheels on the outside and 4 on the inside, each is driven with belts, which reside inside the chassis tube.

Re: Australian 4613 Robot Reveal 2016!!
 

Great looking robot from Down Under!! (or anywhere else for that matter)
Love to see you on the field!!

good luck!!

Re: Australian 4613 Robot Reveal 2016!!
 

Beautiful! My first "why didn't I think of that" of the season -- kudos!

Good luck at competition. Hope to see you at champs!

Re: Australian 4613 Robot Reveal 2016!!
 

The robot looks fantastic in the video! I am very excited to go to Australian regionals with it.Thanks Josh for the awesome vid!

Re: Australian 4613 Robot Reveal 2016!!
 

Are those bumpers legal?

Re: Australian 4613 Robot Reveal 2016!!
 

Very nice, hope to talk to you guys in Calgary - let me know if there's anything we can do to make your stay here better!

Re: Australian 4613 Robot Reveal 2016!!
 

They fill all the bumper requierements. They're just not flat

Re: Australian 4613 Robot Reveal 2016!!
 

10 wheels...wow! Great job, guys - and best of luck at Sydney and WCR!

Re: Australian 4613 Robot Reveal 2016!!
 

Awesome! Good luck this season guys

Re: Australian 4613 Robot Reveal 2016!!
 

Super work. That's a regional winner for sure, and also deserves some engineering and imagery awards. Best of luck!

Re: Australian 4613 Robot Reveal 2016!!
 

Nice robot!
Amazing video, please pass it on to your video team!

Re: Australian 4613 Robot Reveal 2016!!
 

Oh wow, that thing is terrifying! Looking forward to seeing you guys here at Western Canada!

Re: Australian 4613 Robot Reveal 2016!!
 

Great robot! What wheels are you using for the shooters? And what motors are you using? My team is using 4" Stealth Wheels ran by mini cims, geared 1:1.67 with 3" of compression. We are having issues shooting so we may change the gearing again.

Re: Australian 4613 Robot Reveal 2016!!
 

It was great playing with the Barker Redbacks at the week 0 scrimmage. Congrats on making a fantastic robot!

Re: Australian 4613 Robot Reveal 2016!!
 

Wow, this robot looks awesome! Great job!

Greg

Re: Australian 4613 Robot Reveal 2016!!
 

We are using 3.5 inch Colson wheels (hex bore), driven by 775pros with 4:1(5:1 originally, but 4:1 gives a faster launch speed) Versaplanetary gearboxes. 9mm belts and pulleys are used to transmit power from the gearbox to the shooter wheels, so the Versaplanetaries can be located behind the shooter wheels.

Re: Australian 4613 Robot Reveal 2016!!
 

Awesome looking robot and video! I must have watched this reveal 30+ times, and am still noticing things that make me wonder, "Why didn't I think of that?"!

How wide of a range is your ground intake able to pick up boulders from? Also, how do you center the boulders so that your flywheel can consistently receive them, when the boulders are initially intaked from off-center of the launcher?

Thanks

Re: Australian 4613 Robot Reveal 2016!!
 

They may be 4:1 now.... 5:1 wasn't quick enough :)

Re: Australian 4613 Robot Reveal 2016!!
 

Another zig-zag bumper design. Seeing more and more of them. Brando was singing their praises a few years back... ...yet another new trick for this old dog to have to learn...

It never ends with this FIRST stuff. You have to keep watching, keep learning if you want to stay on top of your game.

FYI, my favorite part of this year's Behind the Design was the great pains that Vince & Stephanie went to pull tricks of the trade out of their submissions and reveal them to the mere morals like you & I.

Zig-zag bumpers. Keep an eye out for them. They look like a lot of work. But a lot of smart teams seem to think the work is worth the bother.

Cheers,
Dr. Joe J.

Re: Australian 4613 Robot Reveal 2016!!
 

We'll see how it works out soon! Hopefully it wasn't a waste of time...

Re: Australian 4613 Robot Reveal 2016!!
 

The zig-zag components of the bumpers, were manufactured on a CNC router. The pool noodles, were happy to conform to the shape after a bit of persuasion and restraint. The most complicated and time consuming component was the fabric. A lot of time was spent trying to prevent creases in the bumper fabric.

As Josh said, only time will tell whether it was worth it.

Re: Australian 4613 Robot Reveal 2016!!
 

Thanks Dave! hope to see you and 144 at champs again!

Re: Australian 4613 Robot Reveal 2016!!
 

thanks

Our intake has approx 24 in of useful area, we use a combination of bumpers and a inside frame to center the ball.

cheers

Re: Australian 4613 Robot Reveal 2016!!
 

The feature-set on this robot looks eerily familiar. It is good to know there is hope in this design, and we weren't crazy to jam-pack it all in.

Overall it looks really cool, like an event-dominating robot TBH. I wonder if the zig-zag bumpers will help or hurt with open-field pins. The ability to shoot 90-ish degrees to the right will help a TON if the lighting conditions change at a venue, requiring time to re-tune vision processing.

I am curious about the intake - it looks as if the pneumatic cylinders are able to stop mid-stroke to drop a ball off to the shooter?

Re: Australian 4613 Robot Reveal 2016!!
 

Stop the video at 0:29. There's two cylinders.

Re: Australian 4613 Robot Reveal 2016!!
 

There are two cylinders, the first set push the arm to the ball drop off height. The second set, lift the arm to it's full height preventing it from getting hit by other robots, the raising of the arm also prevents the arm hitting obstacles or the ground again preventing damage. The second set, have a set of flow restrictors which reduce the forces on the arm when it stops at the top of it's travel. They allow the cylinders to act like shock absorbers, preventing jarring and damage to the arm from fatigue.
