Human Players Only?

Well this might seem crazy ... but how are they going to prevent this from happening?

Surely they arent going to count the number of balls that "accidentally" enter the goal and subtract that at the end -- theres no way!

Another problem with doing that is, how are you going to do this all within 15 seconds. You have to figure your robot will move much slower in reverse(since after you do grab the goal[if you do] there is no room to turn around) and knock the ball off while backing up....and if you do get it there, how do you know your partner will knock off the bonus ball...if not, you have a problem. The problem comes in which if you don't knock the bonus ball off in auton...you wait 30 seconds for the auto release. You can't get the balls down anyother way after the auton mode. And the idea of taking the balls down yourself is not allowed. In the manual it says somethinga bout not being able to do that.

<G17> SMALL balls may only be SCORED by the HUMAN PLAYER’s direct throw.
<G19> If an alliance ROBOT assists any SMALL ball into either of their goals, the referee will throw a red
penalty flag and the alliance’s final score will be decreased by twice the value of that SMALL ball.

We were actually strongly considering this as a strategy. Re-reading the rules, I dont believe that this would be going with the spirit of the rules, as they pretty clearly satate that they want all the smalll balls scored to come from Human Player throws. Granted, I think this is an issue that deserves clarification from FIRST to confirm/deny this.

IF it is allowed, then first of all you'd have to have a high level of coordination with your alliance partner as far as timing goes, and fitting it within the 15 seconds would be.......tight, but ultimately it is possible. However, as mentioned before, I dont think that you would get too many this way.

Looking purely at rule G19, I can see how it could be argue either way reasonably well, but if you also consider G17, then I believe it makes it pretty clear that this is not allowed. *shrugs*

Here's another autonomous idea: the robot reaches up from the starting point and grabs purble balls from the big tray. Just an idea, but is it legal? Maybe first didn't think of it.

As far as this is concerned, I believe this would violate the spirit of the rules, and would ultimately go against the intentions of the game........ if FIRST wanted robots to reach high to get scoring balls, then they probably wouldnt have had them drop.

I honestly cant find a rule that really says one way or another. If it is congradulations for coming up with a really creative solution However, I would definately get clarification before I designed for this.

Rule 17 was misquoted in the last post. It goes on to explain that if it is thrown by any other team member other than the human player it will be a violation. It doesn't prove concretely that you can or can't use this strategy. This should be clarified through FIRST.

As for reaching up into the 18 ball hopper, I would say that FIRST could declare these out of play and grabbing them is in violation of rule G22.

<G17> SMALL balls may only be SCORED by the HUMAN PLAYER’s direct throw. If any other team member throws a SMALL ball into the field during a match, that team’s ROBOT will be disabled and the
team will be disqualified.

Theres the full rule, sorry for the partial quote, tried to condense it a little too far :-P. Personally I still take it as being that the small balls must be scored via Human Player, not chute dump, although I realize it is really open to one's interpretation. *shrugs* heck, I know I've been wrong in the past about plenty of things, I think this is one of those issues that FIRST needs a little bit of clarification.

[EDIT] Two teams have already asked this question for clarification in the FIRST Q&A section of their website. Like the others it is currently unanswered, but I am sure we will see an answer soon [/EDIT]

I love this thread.

Here are my thoughts on it. I want to wait and see if scoring with gravity as an assist will be legal first, but I do have a few thoughts none-the-less.

Ok, time factor.. You can uncap a goal and drag it to your station and wait til the 45 second mark to let the balls fall in.

Or if you want it done in autonomous, try just ramming the goal at max speed and knocking the ball off the top that way (Silly Newton's law) and then just driving it in front of YOUR OPPONENTS corrall thus having all "their" balls fall in your goal!!

Remember people, this year we are not expected to drag the goal to our side for it to be counted as our points. So, you ram the colored goal that your side is, thus making the ball come off the top, and without turning around, just drive the goal to under your opponents corall. If you can pull this off in autonomous, and FIRST says this counts, then you are golden!

Remember, once little balls are scored in a goal, there is no way they come out!

Team update #1 has been released! I suggest everyone reads it.
It turns out that scoring by balls fallling directly from the overhead bins into the mobils goal has been cleared as a valid way to score (the rule was modified). so yay for anyone who was planning on using this strategy

[TomWx]

Here's the most current ruling:

<g17> SMALL balls may only be SCORED by the HUMAN PLAYER's direct throw or by SMALL balls falling unabated from the Ball Release into a Mobile Goal. If any other team member throws a SMALL ball into the field during a match, that team's ROBOT will be disabled and the team will be disqualified.

Which translates to: Robots still cannot touch the small balls to get them into the goal. So while the mobile goal may be placed under the Ball release, the robot may NOT act as a funnel or conveyor for the balls.

just like somebody pointed out before in this thread that it might not be possible to get as many balls at a time. you have to work it out with your alliance too. the idea of grabbing the goal and bring it underneatch the 18 balls doesnt seem to be a bad idea. but still i am not sure about how the balls will react once it hits the goal (probably the balls will bounch out of the goal).

[duckshepherd]

I don't see how dragging the moving goals under the ball dropper would be advantagous. There are too many tasks for the robot to perform during the autonomous period in order to successfully employ this plan. First, the goal must be dragged back, then the capping ball must be removed, then the robot must home in on the target ball. There are too many variables to play with, and the chances for success are small. Besides, how many balls would really end up falling into the goal anyway? Maybe two or three. I say go for the target ball first, then see if you can get the robot to drag the goal into your zone as to render tossing balls into the goal more facile. If you go for the target ball first, but fail to drag the goal back, no problem. But if one manages to complete the first task of dragging the goal back, but then fails to hit the target ball within the time limit, one will be penalized with the ball deployment time delay.

Straight from the FIRST website.

Q: Can you move a mobile goal under the ball dump so that when the dump is triggered some balls go into the mobile goal?
A: Yes. See revised Rule G17 in Team Update #01.

Q: Can we put the moveable goal under the ball drop?
A: Yes. See Team Update #01 for the modified Rule G17.

I do not think they would penalize you if a ball went in the goal. A ball may bounce into a goal if they teams anautimous strategy was to prepare by removing the 2x ball. The balls are very bouncy. So if you move the goal under the shout and balls enter it I do not think they will deduct points or hurt you in any way. I am not sure if they will award you points but they should not deduct any.

sorry posted before reading all of post. Ignore above

You can delete your post.

On the subject of getting the mobile goal under the chute.. it doesn't have to be in autonomous. If the balls are not released during autonomous (intentionally or not) you have 30 seconds of driver time to get the goal and put it under the chute before release.

I think autonomous movement of the goal will be much harder (because of 3 other robots able to open your chute while you move the goal) but it is a formidable back-up strategy if the balls are not released.
