Well, of course your partners and your other opponents capibilities would need to be taken into account for this (and any) strategy.

I completely understand what you are saying in respect to ranking points (or whatever they are called now) in qualification matches. But, I think there is some merits to playing each match like it is an elimination match to get ready for when the matches really count. At the end of the competition, the team with the gold medals will be those that won matches, not scored the most ranking points. I think you would be foolish to develop your strategy around the notion that little defense will be played because it hurts your seeding. Of course, basing your strategy around elimination match style, and not qualification style, could leave you watching the elimination matches.

But, when in doubt, I always think, "what would an NFL coach do?". And as Herm Edwards said, "You play to win the game".

Re: Pushing Power?

the seeding points thing makes as much sense as it can until i've seen a competition and know how they work

that being said it also makes sense as xaul said, to play like its an elimination round, because you won't be on the same alliance the whole entire competition (from what i understand), and so if one of those top 8 teams is watching (and they will be), and sees that you have defensive capabilities they want on their alliance, it doesn't matter how you do in the seeding points standings if that makes sense...

Re: Pushing Power?

Truck Town does not get pushed, they only allow their partners to assist their movement.

Though I find it odd that their best year ever (IRI win, national finalist) was a year where they had the same traction as everyone else...

Pushing is limited by either torque or traction. You really don't want to have a torque limited drivetrain (without shifting) as that can lead to extremely high current draws in pushing matches, and once you become traction limited you're "done" as far as increasing pushing force goes assuming an at weight robot. Ideal pushing force = high traction wheel + drivetrain gear ratio / motor combination to cause traction to be the limiting factor + 120 lbs.

Someone correct me if I'm wrong, because then I have a robot to tweak...

342 will see about that in Palmetto. Articulating 8 wheel drive baby, this thing has more stick than Spiderman covered in tar. While 1102 may put up a fight, I plan on seeing a fair number of mecanum bots getting shoved around if they aren't quick enough to get out of the way.

Re: Pushing Power?

I hear about this pushing thing and I'm still wondering what this will do to help the alliance with the brute pushers on it. I suppose there might be an extreme scenario in which there is only one good scorer on an alliance, so pushing that robot around would be an advantage to the other alliance, but is that going to be common? Only one scorer, I mean? Unless your pusher is scoring at the same time it's pushing, you haven't achieved anything useful until it affects the score positively for your alliance. So far, it sounds like "kids" are merely transferring their playground experience indoors. Pushing for the sake of pushing - bah, phooey! Probably not GP either.

Y'know what. I get sick and tired of people calling playing defense not GP.

Just because you decided to take the tradeoff of mobility over traction doesn't mean that it's un-GP to push you. In fact, it may be the best way to win.

While I'm against damaging other robots, I'm not against taking another robot for a 20-30 second ride across the field ... letting them go for 10 seconds ... and then doing it again. It's not against the rules, It's a valid strategy, therefore it's GP (not saying I'm taking that strategy this year).

So, I'm sorry Bill_B (and others) but be prepared, and design for, defense being played and pushing to happen.

The above is JM(NS)HO.

Incidental, quick, or occasional defense is a nice card to have in a lot of games, which traction can give you. The particular reason I wanted to emphasize it this year was because of the ball return. Basically, all of the game objects are reappearing in one tiny spot. I would like to be in that tiny spot. Best way to ensure that is to make sure you require effort to be moved.
