thanks for confirming what we were afraid of.
With bumpers on and being high off the ground, how the heck do you get it from the wall, without a manipulator that wacks it back into play?

I've seen videos of vacuum suction cups that work well, once it grabs the ball. But without rollers, it would make it almost impossible. Those videos showed it with their bumper off.

A robot that has the ability to strafe (swerve, mecanum) can acquire balls with vacuums sans rollers if it strafes diagonally into them.

Are there any videos from any of these scrimmages? I (and I am sure others as well) would love to see them.

p.s. - Please take permission from the teams if you are going to post a video of their robot.

wow,
a post at 4:53am.
At least we got 5 more hours until Monday morning when the sun rises.
We are trying to powdercoat right now, since the team decided to do an all-nighter and got permission to miss school in about 7 hours.:) It sure helps to have our own oven.

Then our programming team arrives at 8am to continue for the next 12 hours................

I have to disagree with you there. This may be true for roller type dribblers, but is in fact easier for vacuum setups.

Re: What did we learn - FIRST Scrimmages?

Another thing we may have learned is due to low scoring perhaps the wonky seeding won't be so painful to deal with after all. While I'm not looking forward to a slew of 1-0 matches I would prefer to not having losing alliances rewarded for being terrible at competing.

Re: What did we learn - FIRST Scrimmages?

well 1-0 matches doesn't sound like anyone was really all that spectacular... And in this case the winners and losers get the same amount of seeding points (assuming no penalties were called) correct? This would benefit the loser.

Although I agree with the point you are making Koko Ed. Low scores will keep this otherwise confusing scoring system relatively simple.

Winner gets their score + 2x losers = 1

Loser gets winner's score = 1

Advantage?
