Intentionally tipping and disabling your own robot FTW...
 

Team Update #2 had an excellent resolution to some questions posed in the Q & A. This change made me wonder about an interesting strategy:

DISCLAIMER: I in no way support this strategy. Please don't misinterpret this post as intent to use this strategy myself or for my team. This question is asked as a result of investigating "game-breaking" strategies, which is something we do as part of our game analysis.

Suppose you built a robot that extended upwards, that if tipped, would block an entire lane of traffic, such that no other robot could pass. Attempting to push this robot out of the way would also be futile.

If at any time during the match, your alliance gained a lead (i.e. maybe 12 to 8 after hybrid mode), if your robot were to tip and be e-stopped, effectively blocking all traffic, would that not prevent scoring for the remainder of the match, thus securing the win?

I would hope the judges would treat such a blatant disregard for gracious professionalism rather severely. The arena is 27 feet wide, which means each lane is 13 feet wide (i'm allowing for a foot for the divider)... The only possible reason a team would want a robot 13 feet tall would be for such a strategy - there's no point in getting that tall to score.

So while there is no specific rule against it, such an action is against the spirit of first, and as such could be dealt with by the judges.

This I would like to see.....have you modeled it in Inventor yet? :)

Jim,

The irony is that in 2005 she had the propensity to tip extremely well... unintentionally of course :D.

As long as we had 842 on our alliance, we could bend it in half.....

Gasp... haha... that is very un GP of you but funny at the same time...

I think that robots will be built much more robust this year.

Re: Intentionally tipping and disabling your own robot FTW...
 

seriously, I really doubt you could block a whole lane with a robot....and I apologize for the un GP reply, but it seemed appropriate to the hypothetical un GP scenario, and funny too, especially if you know 842's robots!

Re: Intentionally tipping and disabling your own robot FTW...
 

well, it is very possible to block almost all of the lane. say the forklift is designed to reach over 6.5 ft. and on your "claw" you have a perpendicular piece that is a couple of feet long (say 3). and on top of that, you have a clamp that would go on top that's another 2.5 ' long.

that is about 12 feet right there... I suppose it could be swiveled our of the way but I have a feeling that this might be happening accidentally a lot.

Which leads to another interesting dilemma. The tipped, disabled robot can incur no more penalties of ANY kind, based on the way the rule is written. This essentially grants the team "immunity" from the moment the e-stop is hit.

1) A referee would be handcuffed in trying to penalize the team for breaking the spirit of FIRST. Even if it was the right thing to do.

2) If you really wanted to cover your bases, you would hit the e-stop as your robot was in the process of tipping, before it tipped to the point of penetrating the 80" diameter cylinder. I don't think robots that tip over, and as a result, extend beyond the 80" diameter cylinder, will be penalized however.

3) Getting through the blocking, tipped, disabled robot would probably mean pushing it hard enough to bend or break something, especially if it was designed specifically for the purpose of blocking. That also poses a very high risk for penalties for the opposing alliance trying to push through, especially if the bumper zone vs non-bumper zone contact penalties are still in effect for the disabled, tipped robot.

Effectively you've created a situation where your alliance is winning, scoring is frozen, you cannot incur penalties, and you've created a very strong incentive for your opponent to take a penalty.

Strategists drool. Gracious professionals cringe.

Luckily the GDC saw this potential situation coming, and threw that last sentence onto the rule:

So anyone bold enough to try this move, you'd better have battle-bot quality plating on there!

Re: Intentionally tipping and disabling your own robot FTW...
 

Any drooling strategists might not have yet fully thought through things. It seems possible that someone might have foreseen this potential little dilemma and already have a solution in mind should any team attempt to use this as a strategy. :rolleyes:

Notice that the (revised) rule indicates that a disabled Robot will not receive any additional PENALTIES. It does not say anything about being immune from receiving a RED CARD (note that in the formal definitions, they are not the same thing).

True, but I suppose there are a few questions:

1) "Pushing" and "ramming" have traditionally been defined seperately from each other, but I don't think they are this year. "Ramming" generally implied that significant, intentional damage would be done to the recipient robot from the collision, which is the situation I'm suggesting here. If a robot needs to be "rammed" in order to clear a path, is that different from "pushing," thus penalizable? From what I understand this year, no. Meaning, you're right, this hypothetical blocker bot could be legally "rammed" into submission.

but does that mean,

2) Is a "legitimately" tipped over bot that happens to block a lane of traffic fair game to be smashed into smithereens? I've seen helpless robots intentionally wrenched, and essentially snapped in two - effectively ending a very good robot's chance at winning champs... trust me, I don't think I could go through that happening ever again.

Re: Intentionally tipping and disabling your own robot FTW...
 

Interesting discussion, but I still think that a team capable of designing a robot that can actually block the whole 13.5' wide lane, without being able to be bent out of the way by a few 140+ lb robots intent on getting by, would be MUCH better off putting their commendable engineering talent to use making a high speed lapper/shooter/ball knocker offer.

Re: Intentionally tipping and disabling your own robot FTW...
 

I know rules from previous years do not apply, BUT I can personally tell you that last year, the refs had absolutely no problem pulling a 72x72 violation on a robot that was intentionally tipped over by an opposing team. I would not expect it to be any different this year.

*cough*

How does the ref know exactly when you hit the emergency stop button?
