I swear I'm going to wake up any moment in bed, it being 5:00 AM, Sunday morning, and this was all a dream.

*For the record, we didn't just magically devise stuff for basketball-like games over the summer. We did a variety of sports, from tennis to baseball, and even water polo (You never know!). It just so happened that during that time we agreed a basketball-like game would play like Aim High, and built off of that.*

I hope it was sufficiently vague, because:

Don't worry, it's legal. We spent 4 hours today checking the rules, and we wouldn't dream of breaking them.

Just though of this while playing Runescape. What if the two robots that we're going on the cooperation bridge left like with 20 seconds left in the game to make sure that it would get done. Would either one of those robot still shoot there basketballs while they are on the bridge, I mean I don't see any rules that this would violate. But correct me if I'm wrong.

Nothing in the rules is stopping you from making this shot, or even a fullcourt shot from the reload station. Physics, on the other hand, may disagree.

Physics never disagrees, it just makes it harder sometimes!

Yes, there is always a way around Physic's. I mean its not like we dont have 3 physics majors helping us this year.

In a word: pyramid. With pneumatic suction capacity. The drive train would be a pair of military tracks to develop proper traction for the platforms. Balls would be sucked up via a vacuum that extends from the bottom of the pyramid into the tip of the pyramid's eye.

An arm would extend from the top of the pyramid, grab the ball, and begin dribbling it to increase the potential angle of impact.

A bit complex, but I feel that the dribbling component artfully captures the spirit of basketball. Woodie Flowers talked about Eat Pray Love, the book, in his speech, and in the book, they artfully capture one woman's soul-searching endeavors. This can capture the soul of basketball!!

Would love some suggestions. Thanks!

I like p1 = p2 more. Momentum reaction forces from throwing might be more worrisome on an unstable platform.

Shame on you for applying a design to a game instead of using the game to define your design. You are all backwards engineers.

Current Robot Seed #1 on Blue alliance and Current Seed #2 on Red alliance are against each other in their last match of qualifying.

Talk about a dull match. Plus, that matchup isn't very rare. Guaranteed #1 and #2 by leaps and bounds.

Actually, it should be 25.37693 degrees when down. 9 degrees would be very nice considering that 5 degrees is "balanced."

A team mate and i used your measurement in CAD and it didn't seem right. So we checked the math in CAD and the measurement we got was 15.83 degrees. We think that when you did your math, you didn't double one of your measurements.
Thanks,

15.8 is about what we got using an iPod bubble level on the ramps at our local kickoff.

From the bumper rules, it seems like the largest gap a team can have on the narrow end of the robot, assuming a width of 27 inches, would be 11 inches, given that bumpers must be extended at least 8 inches from each exterior corner. Is this correct, or are wider gaps permitted?

Your interpretation is correct. That is one reason there has been much discussion and debate over wide vs narrow chassis design this year.
