That's true in some situations, but not all. Hurdles only count over your half of the overpass, placing counts on both halves. There are going to be scenarios where you have the time to hurdle on your half, drive halfway around the track, and place (where you wouldn't have time for another full lap to hurdle). That's a 12 point difference right there, rather than just 4.

That's a pretty good point. I think it's open to interpretation, though, because a shooter robot could potentially get one more hurdle per match than a standard arm robot (that is, if it's fast enough), so the bonus may or may not play a significant role at the end of of a match if the shooter is quicker overall.

This could potentially be an important quality for a robot to have, as a last minute bonus on the opposing stretch of the track could mean the match for a certain alliance.

Ah, well, I guess practice day is going to be devoted to placing a ball on the overpass!

when your stuck in that position yes you are at a slight disadvantage to an arm bot, yet you still have options, such as knock off the opponents ball if it happens to be there, making up 12 points essentially. I know our bot and the robotnauts can do a well aimed diagonal shot to complete a hurdle

Let's just say I'm glad my team won't be up against #1625! Yikes!!

But the main point is that Hybrid Period may be critical. It's potential importance is apparently new, and may catch many veteran teams off-guard.

With a well design ball knocker offer, it would be unnecessary to waste time and energy launching to knock off. It would be much more effective to try to land the ball on the overpass then knock down opponents' balls with the same mechanism used to knock them off at the beginning.

Mostly - as you imply - they generally can't place, and that can mean big points at the end.

But your best point is what everybody else has missed -the importance of Hybrid Period. The best teams may score 1/3 to 1/2 of their points in that period!!

I will have to disagree with your generalizations of a shooter. There will be shooters that can launch from at least half of their home zones using a variable launch angle. There will also be shooters that can launch over the center divider. Please explain why a shooter will have a more difficult time grabbing the trackball after a hurdle. In practice, after a shooter hurdles, the trackball typically ends up against or near the opposite wall where it is very easy to pick up. There will be shooters that can grab a trackball as fast as any armbot and at the same time have the trackball loaded for another hurdle. Granted, most shooters will not be able to place, however, there will be shooters that can remove the trackball very affectively. I do agree that Hybrid will eventually produce at least a third of an alliances points.

Or, what would be an even more effective (albeit amazing) idea would be to launch your ball into an opponent's trackball (which is sitting atop the overpass) in such a way that your ball lands on the overpass after it knocks off the opponent's ball! Instant 24 point difference!

Forgive my musings. It's late, and I've had a bit too much Dr. Pepper today...

I have read pretty much all of the post on this thread and I am impressed with many of the arguments

Just so you know where I am comming from our robot is a shooter. It however does not use pnematics to "shoot" "launch" the ball. Go to www.frc272.com and maybe you can figure out how we do it. Look under "We are LC" "2008 season". Anyway our robot also employes an alternate aparatus that can effectivelly remove the ball from the "monkey bars" "rack" whatever it is you call it.

However I am not at all saying this is the way to do it. We just like that fact that we can move on the fly and shoot. Also since we can remove the ball from the rack using an alternate aparatus we like it. Anyway

I have been lookin at a whole lot of video of other robots and I believe it just comes down to speed, quickness of picking up the ball and if you are a lifter doing it as fast as possible. If you have all of that I do not care how you do it you are getting it done fast and often and probably can keep up with anyone.

I also read some threads about it is easy to block a "shooter" "launcher" and while I would agree with that. I would recommend to teams you avoid it. Just as an example I had one of those moments and walked in front of our completed robot just as it fired. That ball almost took my head off. In retrospect it was very funny but the forces of that fire took a 210 pound man and put him on the floor. I just think if a lifter decided to get in the way and took a shoot either the robot may sustain fatal damage our it might be out for the count if you catch my drift.

Any who I think in the end if you built a great robot no matter how it scores if it is quick, accurate and efficient. Oh and a killer autonomous/hybrid would not hurt it really wont matter.

[MrForbes]

It looks to me like the 1726 robot will hurdle reliably if we are moving fast, and will be able to place the ball reasonably reliably if we stop before shooting.

I expect several teams with shooters will discover this is the case.

Now, about that backspin generator....(oops! that's a secret, isn't it?)

[lukevanoort]

In my view, good shooters will dominate good arms. Good arms will dominate bad shooters. Bad arms will just lose. I also think that we will see more good arms than good shooters (teams have more experience with arms), so good arms will appear to be the winning design for many competitions. In other words, I agree with Craig's basic idea, but disagree in practice.

As for placing capability, I feel that it will win many qualification matches, especially early on, but not as many elimination matches. Kind of like dumpers in '06; a good dumper won lots of qualifiers, but they had to find a good shooter or two to ally with for elims or else they were toast. In contrast, I think at least one divisional final, and possibly the whole championship, will be decided by placing (like the balls in 2002). At that level, both alliances are capable of scoring ludicrous amounts of points - it'll be that small little boost that pushes one to beat the other.

Hurdling doesn't seem to be the hard part. From scrimmage videos so far, picking up seems to be the worst, just because of the traffic jams and balls everywhere. A robot that can quickly get a hold of the ball and into its possession will waste less time there, and be able to get to hurdling faster. For hurdling, the teams that I think will do well are the ones that get the ball just over the overpass. The ones that launch and shoot it way over will waste time having to chase after that ball or the other ball.

I agree that cycle time will be important. Hurdling fast, but pick up slowly doesn't have an advantage to a robot that can pick up quickly, but just hurdle at a medium rate.

No one still really doesn't know what a true winning strategy is because we don't have many repeated 3v3 matches to see what works best. Saying that one robot on an alliance will win is probably just your own preference for a winning design. Also who knows, it may be like last year where ramps became biggest part. It may turn out that no one can reliably pick up and hurdle balls with 5 other robots trying to get around the field.

[Mike Schreiber]

I think the chaos will be cause for much flipping, flimsy arms and overly precise arms won't help either, but as said above, we have no hard evidence except for scrimmage videos...this is all speculation. I'm not sure many people would have called that the ramps would decide the game last year. Who knows...

I just read all of this and see a general pattern. Generalizing shooters, arms, and racer bots. We forget that each team will have diffferent degrees as to how effective they will be with their respective designs.
Driving and practice makes a big difference. How many times have I seen the Poofs win regional competitions simply because they were the best drivers out there, making very few mistakes, working with great efficiency. They maximized the capabilities of their robots consistently, regional to regional, year to year. That's what impresses me the most about them.

How teams setup controls of their robots are key too?
I had two sets of drivers practice with our robot and it was like night and day. One group had me thinking that our robot couldn't even hurdle. The other group allowed me to sleep that night, proving that our design worked.

Is it safe to say that every year, the best designed robots and best alliances dont always win, for one reason or another.
I still cant believe the Poofs havent won a world championship yet????
