As long as the discs exit the pyramid above the 60" rung you can't block them.

Well, lets just say I think your team is especially clever :]

That's not my team's strategy, that would mean we were shooting from much to far away for our tastes. That's the strategy I think most "good" shooters will use.

If you're scoring it as most people assume, with a 30 point climb and 20 point dump, then I would say that it may not be enough. While most likely a consistent method of scoring, potentially has the issue of being capped at 50 points. Possibly more if you can dump in autonomous and during the match, but you'd be hard pressed to break 65-70 points per robot.
If you're scoring the 50 points by shooting and a 10 point hang, it may be better than a 50 point climb/dump. Reasoning: The 18 points in autonomous should be a given. As well, a 10 point hang should also be a given, especially with designs like Spectrum 3847's simple passive hanger. That leaves 22 points to be scored by a shooter. Which is three full hoppers of frisbees to the top goal. Entirely do able in a minute and thirty seconds. Why this is better: This robot would be easily improvable to surpass 50 points by either making more trips to the feeding station (Driving practice = ability to dodge defenders or ability to change drive ratio for faster drive train.) OR the ability to add a floor pick up system and VASTLY cut down on trip time whitch would easily make 4 or 5 full hoppers feasible.

TL;DR a 50 point shooter could be improved upon. A 50 point climber is essentially capped at 50 points. You won't know until competition whether 50 points is a lot or a little. You may get there and teams "bluffed" their accuracy in their videos. You may get there and find out that all the shooters are bats out of hell and dang accurate.



A robot climber is limited? depends on your point of view .... you are considering that the frisbees will be dragged pills etc ... or do you think every game will put 118 new frisbees? is taking into consideration that the kickers will always be shooting in the same place? the first to the last game?

A robot climber who can in 30 seconds to be on top of the pyramid will have approximately 60 seconds to make your strategy, help your alliance? hinder another alliance? this will be in charge of its strategy and its alliance. I think a robot that can do various strategies during the game, not a robot limited...

It is now week 4 and by my count this is one of perhaps only a handful of videos of a robot completing the task....
...As I'm sure a lot of people have realized, designing a 30 pt hanging mechanism is really difficult. It's probably gonna weigh a lot and take up a lot of space... :D

Agree completely...with one exception...not many have posted videos and partially because it is such a challenging task that many have steered clear from it (or maybe they are just playing their cards close to their vest :cool: calling Robonauts and Robotwranglers :yikes: ). On the other hand heavy? Hmmmm...88lbs compared to the 119.7 we hit last year doesn't seem so heavy to us :D

Re: 50 POINTS
 
If you can score 50pts by yourself you will be a top 5 robot at almost every regional/district event unless you have really bad scheduling in which case you will be a first round pick.

Most people will claim they can score 50 pts or better but very few will truely succeed. My belief is that less the 70% teams will even score 20 points more than once, yet people will fixate on what is possible by the top 5% and think that the round team XXX scored 80 points is reasonable or normal as they do every year.

What we always look at is what is theoretically possible, but the reality for most teams is far lower because it is hard to aim a shooter and many teams will have little if any stick time on their robots before their first/only regional so the driving will be a lower quality than the later events.

In their minds people always think of the elimination matches at later regionals/districts or the championship where many teams are on their second or third event and the caliber of play is far better, but your average qualification match is generally low scoring and pretty aweful to watch.

I would set the over under of the average robot at 15.5 points this year.

That said just climbing and dumping to get 50pts is not a Championship winning strategy. It will probably work at a week 1 or 2 regional at most but the strategy has too many flaws particullary if that is how you play every match.

I feel like this is entirely backwards. Any good 50 point climber will have a target on its back; defenders would do well to prioritize tying them up. You're not going to have much time to play defense yourself if you're up against good defenders ...and/or against 2 of them, which is not unlikely in quals as one opposition shooter scores and 2 defenders bog down the Climber and allied traffic. I know we'd be more than happy to trap a 50-point climber in one of the dead zones they'd want to move through, and I'd also be psyched to go head-to-head with 2 bogged down shooters while my allies play D.

In short, if you're a 50-point climber and want to play valuable defense as well (particularly in elims), you better start preparing yourself to be an actual defender. Unprepared robots on D is rough enough; doing it unprepared with a target on your back is nuts.


TL;DR: Seriously, climbers -- I know at least half a dozen teams at my first event alone who would be more than happy to make you spend the entire match just struggling to get to those colored disks and back to the pyramid.

This, all of this.

Many people seem to forget, as we often do on CD, is that we are not all powerhouses, nor should every team aim to build a powerhouse robot. (Don't try to build beyond your means, etc.)

A team that fields a robot that scores 50 points in every match that it plays will, without a doubt, be in the upper middle tier at MOST regional and or district events. For those of you that haven't been following twentyfour, I suggest that you read into some of the posts.

To continue on with the 50pt discussion, if a team were to score 50pts by doing a Z3 climb, and then scoring 4 colored discs into the pyramid goal and do nothing else, this is what a robot would have to do in the same time to offset the points(assuming Z3 Climb and score has no auton):

- Score 2 Discs in Auton in the High goal, and score an additional 9 discs in the high goal during teleop along with a Z1 Climb.

- Score 2 Discs in Auton in the High goal, and score an additional 6 discs in the high goal during teleop along with a Z2 Climb.

- Score 2 Discs in Auton in the High goal, and score an additional 13 disks in the high goal without any climbing.

And the list goes on...

Notice how each of those alternate methods of scoring points rely on a few key things, notably autonomous scoring, the ability to reload at least THREE times during teleop and to be able to reliably climb. Using previous years as a guideline, I highly doubt 50% of teams will be able to do the above consistently.

Also, it's worth noting, that all of the above, assumes the Z3 Climb and Score Robot takes 2 minutes to do so. If they can get the total time down to 30 or even 45 seconds, they have more than half of the match to play defense - which, depending on how you look at it, is just as good as scoring points...

(PS: to the Z3 climb and dump teams, you can actually score 60 points with this method - if you're willing to take 6 foul points while doing it... Just sayin'.)

I know you're kidding, but will people please stop considering this a viable strategy? It was a good laugh week 1 but I fear there are some teams seriously considering designing for this.

Obviously a shooting robot will have a MUCH easier time getting by those same defenders to the feeding station and back into a shooting position.

We actually looked at what you are saying as an advantage in our calculations for our strategy. We figured a team that had an awesome frisbee shooting capability would have a huge target on their back. Now you can only carry 4 frisbees at a time and then have to get them from somewhere giving the other team a chance to defend you. You can also be defended while trying to shoot. Since you will be making many full field trips, there are many more chances for a team to keep your score down.

We built our robot short so it could drive under the pyramids and not have to worry about "dead zones" and we only have to make the trip across the field one time. A defender or two has to concentrate the entire game to not let us by, and which is easier, them getting lucky the whole match, or us getting lucky and across the field ONE time? The pinning rules and safe loading zones should easily allow one round trip. And we seriously hope you try and defend us when we are touching our pyramid since that awards a 30 pt climb automatically which will add to the 30 pt actual climb of the robot and 20 pt dump. (Our 50pt robot just became an 80 pt one)

I think any 30pt climber, 20 pt dumper will be difficult to just lock out of the entire match without occuring penalties or tying up 2 of the other teams robots. And those two robots defending are not scoring themselves still giving your alliance an advantage. It's a team game, and if my one robot focuses your attention so much that my other teammates can score enough to win then I still come out ahead.

That's just how we saw it when we did our strategy meetings. YMMV. :-)

Re: 50 POINTS
 
Good is an understatement.

You would win most week 1 and 2 regionals if you can score 50 points by yourself EVERY MATCH.

I'm not at all surprised at the serious optimism in some of the score predicitons on this thread, this is business as usual.

Sean Raia has spoken.

It's not a joke. There is nothing wrong with taking a penalty for a net gain in points, unless the rules make intentional penalties a Yellow or Red card offense. The Q&A is somewhat ambiguous here...

I wish they would address the specific case of carrying more than 4 colored discs with the intent of scoring in the Pyramid Goal, but that is probably to narrow of a situation to be answered directly in the Q&A.

It will be good to learn from teams who attempt this at week 1 regionals and see what the ramifications are, if any.
