Strategies for Rebound Rumble

So, one possible strategy would be to play 2F-1B (2 forward, 1 back). The job of the F players is to scoop up balls and put them in the goals. These would be the primary point scorers. B's primary responsibility is to play defense by preventing ball starvation of the F's. B's secondary responsibility would be to avoid committing penalties. Given the many ways to commit fouls when on the defensive side of the field, this may be fairly difficult to do. Sort of like walking in a minefield.

A B robot could be made exactly like those from the 2010 game and be pretty effective. Of course, the ability to score from the defensive side of the field would be even better. But, even shooting and missing gets the B's job done.

A common and fairly effective strategy in Breakaway was to have scorers and feeders. I expect to see something similar this year, and probably every year with a goal-zone set up like this.

zone defense or robot on robot defense?
---> having zone defense will probably be the best strategy since it allows two of your robots to continue scoring. and the robot that plays defense should be able to shoot balls across the field- there might be a chance that the robot makes the shot but it gives its alliance more balls to work with without going back and forth across the field.

Does anyone have a video of the balls bouncing over the bridge?

You wouldn't have to bounce it over the bridge. If you enter it into the field at a slight angle, you would only have to make it over the 6 inch barrier.

Very true, and completely understandable. I may have initially underestimated the size of the key, but there appear to be a few safe spots for opposing robots to starve balls. For the B robot, as long as the balls get to the offensive zone, B is doing his job. As stated before, shooting into the hoop would be a 2-in-1 deal.

A defensive bot will be effective this year no matter if another bot is taller. If a bot is in the key, I don't know how many teams would confidently put a shooting mechanism on an arm. This means that if the ball has to be lower than 60 inches, it will not matter, and of they try to put it into the basket, a defensive bot should be able to push the opponent away.

For a general scoring strategy, I was thinking of using a similar strategy to ours last year, using an encoder to put our shooter into a position so if the strength is set to a certain limit, it would hit the same spot and the have the same outcome each time. Doing this right at the hoops, will almost always give the desired results.

A reliable shooter in the key is going to be the clutch. If you could put a retriever in the lane to get balls and launch them into some sort of hopper on the shooterbot you could stay in the "no-touch" zone most of the match.

Something I see is at least one main shooter robot that can accurately fire into the top goal by sitting in the key area, one robot feeding it, and another either defending or staring the other team.

In the spirit of FIRST, I see a great strategy in cooperating with the opposing alliance to balance on the middle bridge. This "coopertition" not only gives you points to qualify, but is also a major component of Gracious Professionalism.

Besides the "coopertition" strategy, alliances going for their own bridges is a major point-scorer: 10 points for 1 robot balancing on the bridge; 20 points for 2 robots balancing on the bridge; and 40 points for 3 robots balancing on the bridge during elimination matches only. If alliances get any robots on their bridge, it will be a major advantage.

Another strategy for "Rebound Rumble" is scoring in hybrid (autonomous). If an alliance scores all of the balls they receive in hybrid (6 balls), a maximum of 36 points can be racked up. This puts said alliance in a winning position that would be very hard to catch up to.

Saying all of this, I believe the best strategy would be to score as many high pointers during hybrid, and then during the last 30 seconds of the match have two robots of the same alliance balance on their bridge while the other robot balances with an opposing team's robot on the "coopertition" bridge. Excluding teleoperated ball scoring, that is a total of 56 points!

I hope team benefit from these strategies.

Message 13 provides a link to the episodes of the field tour, but it starts at episode 2. I've looked for episode 1 with no luck (too much search noise on utube). Is the first one worth watching? (the others were.) Where is the first one?

I was thinking that if you had a robot that could score in the lower or middle hoops 90% to 100% of the time it could stay in position right up against the hoop, then we could have another robot picking up balls scored from the feeder and shooting them right at the collection system. If they are aimed well and they can be moved before there are 3 in possession of a robot, then we could really rack up a lot of points.

I saw a note there that said they decided not to publish the first episode, so it starts with episode 2.

Does anyone know what the first was supposed to be about, and why they decided to suddenly not release it? In the series, they say it has 6 parts, while now it only has 5.
