It is the Allen Bradley 42EF-D1MNAK-A2 from last years' Kit of Parts.

I know why. Nice looking robot.

Thank you Jared and Team 341, do you have an upclose picture of your shooter and encoder setup ?

[Jared Russell]

Here is a closeup of the shooter.

The sensor is on the left side of the picture, and two retroreflectors are mounted 180 degrees apart on one of the shooter wheels.

Wonderful bot.

A couple of questions:
1> when your manipulator flips out it looks like it breaks the front plane of the bot in more than 1 location. Are you concerned that it might be ruled 2 appendeges?
2> when your manipulator is deployed it appears to obscure your numbers. Is that just the angle of the picture?

Otherwise, the bot looks gorgeous.

I'm not sure why that would be a problem

Game - The Robot » Bumper Rules
Q. Can the bumpers be covered at any point by a dynamic appendage on the robot?
FRC1648 2012-01-14
A. There are no rules prohibiting this.

The entire thing is articulated as a single assembly. It is difficult to see from the photo, but there is a reinforcement bar all the way across the width of the bot right at the point where we cross the frame perimeter (on top of the bumper). We momentarily break the plane in two separate places during the act of deployment, but that has been explicitly allowed via Q&A and Team Updates.

As for numbers: from a full frontal view, you can actually read them just fine when your intake is deployed. The intake is mostly air

I do too. I wonder if penalties will factor in, because with such a wide intake you know they'll gain control of more than 3 balls if 4, 6, 8 (etc) balls exist at the ... errm, wrong ... spot. Of course, with the right timing that won't matter. There are other indirect fringe benefits to such a strategy too. (We might have the same issue...)

Can't wait to see this bot in action!

The intake naturally self-limits to 3 (at a time) when gathering from a bridge.

Sorry for the thread resurrection, but I was wondering what the flat belting material you guys used for your intake and elevator was. It looked similar to the flat urethane belting here:

We are looking to build an intake and elevator in the offseason, and we were curious what it was and how it worked for you. We used the round urethane belting from McMaster this year, but we had a lot of problems with it walking across the pulleys, it looks like you didn't have to use anything to keep the belt in place. Thanks!

McMaster #6075K15 is the belt we used.
It was awesome and reliable. Very little, if any stretching. No failures and tracking was simple. Just build up a crown of electrical tape under the belt and it naturally centers.
We did have to experiment with various ways of welding the belts. But that was also not too bad to figure out. This belting was just right for this application.

I just wanted to say, this robot should be an inspiration to teams everywhere. It was not built by professional engineers, and it wasn't machined to pieces. However, it was still one of (if not the) best robots in the country. Congratulations Miss Daisy, you are truly a role model team and very well-deserving of your Hall of Fame title.

To quote Jared, "every part of that bot was precision machined... to within 1/16th of an inch"

Machined? I thought Miss Daisy grew all their robots...

There was definitely some precision work that went into this robot (the shooter side plates and guide rails were laser cut Delrin, as were the bearing retainers in the drive and a few motor mounting plates throughout the machine. The belly pan was waterjet by a sponsor). Our engineers (all four of us!) worked side by side with our students on every aspect of design and construction of the robot.

But for the most part, our robot is one that 90%+ of FRC teams could have built (though our heavy reliance on COTS parts such as gearboxes and wheels generally pushes our bot towards the upper end of the allowable total cost). Except for the parts I noted above, all of our machining and construction was conducted in our build space, which is pretty low tech (a small low cost mill and 3-in-1 lathe plus wood shop tools).

Our design approach this year was simple: Build the simplest possible machine that could execute our desired game strategy (3+ ball hybrid, effective key shooting in teleop, and triple balancing), add in some killer software, and never stop improving/iterating.
