Strategies for Rebound Rumble

i don't think you could touch the basket. It is a height limit...
You will still be limited to going outside the frame perimeter ..
You are allowed a single projection of 14" ... with a 3" bumper your projection is only 11" outside the robot bumper.

The unit at the bottom of the baskets extends 38" approximately from the wall.
So your frame perimeter is approximately 41" from the wall.
With a 14" extension that would mean that you would be 41" - 14" = 27" from the wall...

I am not sure how far the hoops stick out... but with a 20" circular hoop and its associated hanger it is pretty close.

i would imagine that the game planners figured this out pretty well so that touching the hoop would not be possible.

Obviously no matter what size the hoops are... no one could EVER touch the top hoop...(it is beyond the allowable height...

Big strategy = ball control.
Your inbounders hold their 2 balls each, your robots hold their 3 balls each, and suddenly the opposing alliance is ball starved to only 3.
you keep one robot right in the alley to shoot back across the court whenever an extra ball is scored and an inbounder has to let one go.
Thus each time the opposing alliance scores they have to drive all the way across the court to get the ball again.
Balance for bonus points and the win assuming your opponents cant.

I think the better strategy is robot control if a good defensive robot is able to keep the opposing team on their side of the bumper, while picking up balls rom the key and shooting them back at their alliance, their alliance members will be free to pick up the balls from the opponent's key, and score again, creating and endless loop of scoring and restoring. Now 3v1 would be hard on the defending robot, so maybe 1 big scorer that does the repetitive scoring and 2 defensive robots. Once you get over the bump/bridge, it becomes easier to stop others from doing it. Plus, you can practice ball starvation that way.

Weaknesses in this strategy:
1> when your opponent scores you also are assessed a foul because you now have a ball in the corral that none of your inbounders can immediatly take (they each have 2)(and even if 1 of the inbounders enters a ball onto the field they will be out of position to immediately take a ball from the corral).
2> The recieveing robot is in your opponants alley, and if contacted (regardless of who initiates the contact) will incur a foul.
3> you assume your opponant cannot balance ... I'd not make that assumption.

The problem with this strategy is what you will do with these balls once you have them. Either you end up starving yourself, being forced to let go of a ball, or you try to score – which puts the balls right back into the opponent's hands. And that's not including the other 3 balls that you can't control.

That being said, this idea is still very useful as a delaying tactic.

Yes you starve yourself as well, but this strategy is more for a team that is playing against high scoring bots, and likes their chances better at relying on ramp points.

I believe the secret is actually in the coopertition bridge. If you create a robot that can line itself up on the bridge and it would be right in line to score. Also, by remaining on that bridge for periods of time, the opposing alliance can only use their own bridge. Also, towards the end of a match, you're already where you need to be to possibly score coopertition points!

Make a robot with a ramp allowing another robot to drive on top of you, and you then solve the problem of how to get 3 robots on the bridge. Also, you can use it with your opponent's robot so you and your opponent can easily balance on the Coop bridge together as one entity rather than two.

Our team 1111 tried that i believe 2 years ago, it did not work at all, but if your team could pull it off, with enough time after and before your done making it to calculate the proper weight distrapution it might work. An arm to keep it down might also work.

According to [G23] Robots on the same Alliance may not work together to blockade the Court in an attempt to stop the flow of the Match.

Our team was thinking of just waiting underneath the hoops on the opposing alliance's side. This way, for all the balls that are missed, they could fall into a funnel on our robot that would focus them into a launching device and shoot them back onto our side.

So based on this idea, is our robot allowed to remain in front of the hoops for the whole match as long as it is under five feet?

Yeah, you're allowed to do this. But make sure you have a way of stopping the balls from entering the funnel. Once you get more than 3 balls its a foul. And the other alliance gains points.

For EVERYONE- not matter defense or offense- make sure you have a way of picking the ball off the ground. Even the most perfect robots will miss the shots from different angles- its a great chance to get rebounds and get some easy points!

I love the idea of coopertition but honestly I believe the best way to score points is 3 robots on the alliance bridge. Obviously during qualifying it would be very hard to do but once in elimination you have an established alliance. You can then focus on finding the correct way to balance all 3 bots and score 40 points. That could easily turn the tides of any match. Especially when this year's game is so reliant on an accurate shooter for high scoring matches. One thing that Im going to bring up with team 1678 is to make a computer program which you just input the weight and some other values into it and it outputs a configuration for all 3 bots.

Another strategy I have thought of is to have a bot sit right at the inbound station and pretty much have the inbounder hand load the bot which then fires the balls across the court and to the other alliance members. This would help keep from ball starvation and allow the inbounder to be more effective.

[MikeReilly]

For Rookie Teams: consider making a very small bot that can easily squeeze onto a bridge as the 3rd, and can herd balls to your alliance, or maybe flip them over the barrier. This will make you a very desirable 3rd pick for Eliminations.

Also think about the three offensive robots, each up to 84" tall, right next to each other in the key shooting at baskets: Will you be able to shoot past or over them to get balls back onto your side?

It seems like you might be confusing the scoring systems a bit. The coopertition bonus only applies during qualifying matches, where it is worth as much as a win; getting 40 points for balancing 3 robots only applies during eliminations (otherwise it is worth the same 20 points as balancing 2 robots).
