Bronc Botz Team 3481 '13 - Twister

[dodar]

This does look like a really cool robot and it will be cool to see this play with both robots from 1592 and 801. Do you guys have a video of it in play?

Not ready to release yet... still working on twin practice bot to perfect subsystems/programming/practicing... LOADS of work to do...

Our team name should probably be "Bronc _Iterating_ Botz"...

Looking forward to meeting you at Alamo! ;-)

Are you using 8 CIM's?

Looks like a 6 Cim drive, 2 Mini-CIM shooter, and 2 BAG intake.

Gregor has it correct. The lift in the back is for climbing, however we are still working on the hook design, so you don't see those in the image.

Parker, you and the rest of team put together an awesome looking robot. I can't wait to see it up close next week. We're pit neighbors too.

Are you shifting with the 6 CIMs or is it a power takeoff for the climber?

[AdamHeard]

I like it.

I think I found my new favorite bot this year. Can't wait to see this in person at LSR. Good luck this year guys, I'll be rooting for y'all!!

[ParkerF]

Thanks for all of the compliments, guys.

Allen, it is indeed a PTO from the 6 CIM drive. We're running a single speed drive due to this. I don't have any good pictures, so you'll have to come by to see the mess that is that PTO set up.

Congrats on a very unique and intricate design.
So many things are happening on this robot !

I'll start with a shooter question,

Mini-cim shooter gear ratio, what gears did you use ?

Andrew,

We're running at 1:2 on the front wheel, and ~1:1.2 on the slower wheel. This was all based off of our prototype. We will continue to tweak speeds with software, so hopefully that gives us some more variability.

Cheers,
Parker

I'm getting some questions about the helix/lift subsystem (aka Felix the Helix)...

And YES, some of the "magic" is missing from the center of the helix... we're STILL iterating the spindle on the twin...

VERY cool visual when those discs spin-up the helix to the feeder (bucket)... ;-)

Thanks Parker ! We have switched to direct driving mini-cims in prototyping on our practice robot shooter. We have not quite figured out a great way to swap in a geared up mini-cim system into our shooter.

We feel that your shooter gear ratio has just the right amount of speed/torque to really launch the frisbees.

Have you tried doing full court shots ?

On a sidenote... I wonder if 148 has any shared design features as 3481 ?... it would be nice if 148 released a picture or something...

Andrew, we've got Grayhill encoders all over the bot, two on the shooter. Grayhill is new to us this year and we're currently in the process of tweaking different speeds AND wheel durometers on the twin (Yes... I used the word durometer... LOL) to get max distance... so we'll get back to you on max distance or we'll show you next week.

On sharing ANY 148 design features between our bots... I believe the only thing we may share is sheet metal construction and awesome powder coating... AND a chit-load of VEXPro parts.

I don't know A THING about their bot this year. MAYBE Parker does, but he has EXTREME integrity on secrets... and darn it, arm-twisting DOESN'T work with him... LOL

I'm one of 148's BIGGEST fans (in more ways than one) and I'm excited to see next Thursday WHAT they've built!
