Wow very impressive as always.

Can it shoot down though via tilting hood?
Its not hot pink =(

The design work is absolutely amazing. I can't imagine how many hours went in to all of the CAD work. I have the same question...can you shoot down? Also are the drive modules machined tube again?

I love the bot and it would be awesome to see some video.

did y'all manage to use all the motors in the kit this year?
lol jk, great looking robot.

I didn't doubt, but that made the anticipation level just plain painful.

Lots and lots of CAD.
I can truly say that this build season, of my four years in FIRST, has been the busiest, the most stressful, and the most work I've ever done. I've loved every minute of it, and learned more than any other year.

As to answer you question, it cannot tilt down, but we have a magnetic sensor on the Fischer price gear box for the flywheel that monitors rotations, we have programing so that the closer the trailer is, the slower the flywheel spins, thus adjusting how far the balls will go. We utilized similar ideas on 2k6.

If any team can pull off a shooter without an adjustable hood it will be you guys. I hope it works for you. How many balls per second can you guys shoot and do you have the tracking working well?

Also just curious...how much sheet aluminum do you guys go through?

Sorry, I missed your other question.

Yes, the drive rails are 3x3 box tubing 1/8th thick aluminum.

Many similar ideas, yet everything as always has been modified, been made smaller, lighter, and hopefully better : )

No pink or telescoping arm...

Very cool though!

Ahh very nice. Can't wait to see it in action.

Just curious, but why did you abandon the human loaded hopper? Orbit balls getting jammed going into the shooter feed?

...I plead the 5th.

I believe the turret rotates to about 233 degrees (oh okay close to it... don't remember specifically). We carry roughly 14 cells.

Pro.E
You are probably thinking about Roccobot 2k or 2k2. No powdercoating this year. We left it gray and angry.

I would like to answer these questions (look up for amount of cells we carry) but we have some serious work to do on Thursday in hopes of improving our numbers to a more acceptable level. So sorry, won't give exacts. Ask again after Thursday.

Thanks Alex and Dillion, we will keep that in mind on Thursday. Video of us powering Roccobot 2k9 for the first time.

Holy Cheesehole batman

[Dan Petrovic]

At least the bumpers will be pink...right? *sob*

These robots are always impressive when you think of how much CAD work goes into them. This team is blessed with machine shops that can keep up with the drawings that are being fed to them.

233 may have themselves a third Einstein appearance in a row.

This thing looks amazing I can't wait to sneek a peak of it on Thursday kinda sad about the lack of pink on it I really wanna see how you guys did you wiring this year
