Ramming and Hitting

[Angelfury126]

I'm wondering how aggressive teams can be on the field? Can you ram other teams from across the field or does that only apply to the ramp?
How bad can a robot hit or ram another robot until officials intervene?
I'm under the assumption that its a free for all and that you can go out and just punish the other robots on the field.

when you get your robot done, and you have put 6 weeks of your life into it, and you know its strengths and weaknesses

then think about how hard you will want another team ramming your bot?

and you will have your answer.

aggressive play is only allowed to gain a decisive field position or scoring position. Ramming or bashing a robot to disable it, or to knock it over will get your team disqualified.

In FIRST we don't use force to disable a robot...You can push, shove, and "hit" a robot; but intentionally ramming a robot from across the field is grounds for DQ. I've been a ref, and have had to make those calls...trust me, ramming a robot to defend a goal is one thing, but to ram them just to ram them is uncalled for. Use your best judgement, and always remember..."Gracious Professionalism" (Don't do something to another robot, unless you want it done to yourself)

FIRST is more of a sport than, say, Battlebots. Some contact is allowed, but within reason. Think basketball or something.

[kborer22]

you will be warned once, and if your lucky twice, but this year especially since there are no field elements to slow your down there will be A LOT of ramming penalties. And you will be frowned upon for malicious ramming...

[Kevin Sevcik]

To clarify, the Rules specifically state that ramming with a head start from across the field is illegal. As are strategies aimed solely at the destruction or disablement of other robots. As Ken says, pushing and very limited ramming are allowed solely to gain a positional advantage on the field. You must be trying to get somewhere or keep someone from getting somewhere, not attacking their robot. The only leeway given on the ramp is with respect to pinning.

Even a cursory glance at the rules makes this clear, so I'm uncertain where you got the impression that this is a "free-for-all".

Owch! Ive never seen a robot jump over the railing and start ramming an opposing driver, but I guess it could happen! :^)

Remember I believe that if you are goinjg to hit some other teams robot at full speed you cant be any further away then like 3 or 5 feeet. Someone please verify with me. But do u think that FIRST is going to disable those bots that are in a low gear and move at about 2ft/s get penalized if they are moving from across the arena and hit another robot and push them. Will that be classified as ramming because if they were to stop at 3 ft away the other robot could just move. I have looked throught the manual and as a senior I should know this, but is there a max speed that you can go when hitting another robot?

[Travis Hoffman]

I really wish the FIRST community would stop using the word "ram" to dually imply illegal actions and also perfectly legal bumping and pushing. It confuses people. There is no such thing as "good" ramming.

I'd like the word "ram" to be connotated negatively 100% of the time and be defined as any sort of illegal intentional hit initiated from a distance of greater than 3 ft. away from the targeted robot. I believe 3 feet is the accepted threshold.

When we post on this subject, please do not use the term "ram" to describe any legal robot interactions. "Bumping", "pushing", and "shoving" are much better descriptive terms here.

If a robot is in "low gear" as you said, that's not full speed. If a robot is moving at say 2 fps, you will not see a penalty or DQ, however if you were in "high gear" moving at another robot from across the field, need I even say the outcome? Let's try not to paint a grey area in what is now white or black. USE YOUR JUDGEMENT!!!

[Lil' Lavery]

Keep in mind that this year there are very clearly defined areas you may come into contact with other robots (aka "bumper zones"), and any contact outside of the bumper zones (unless clearly unintentional or coincidental with bumper zone contact) can be penelized. Although, if a robot expands beyond the original 28x38 starting dimensions it will forfeit any protection from the bumper zone rules it has.
So, if the contact is low I think there will be much much more leniency twoards you that if it's high, but "charging" or long-distance ramming will still be a risky decision no matter where you hit the other robot.

[Eria4044]

There are five reasons to not want to ram excessively.

1. Not GP.
2. Penalties
3. Anyone ever heard of the more negative version of the golden rule (I think it originated in the Far East)? Basically, it's "Do not to others what you would not have them do to you."
4. You're not going to make any friends.
5. There are other ways to win.

You may want to read the rules. There's all sorts of knowledge in them.

FIRST is not Battlebots! Our rules are more like soccer: full contact within reason.
Some rules here include: No high-speed ramming from across the field; No contact outside the "bumper zone" (2.5-8.5 inches from the floor); No pinning a robot for more than 10 seconds (except on the ramp). Also, as Kevin said (and the rules say), strategies aimed at destruction or tipping of other robots are prohibited.
So, don't assume it's a free-for-all. It isn't.

(I'll post exact rules with numbers when I can, unless someone else does it first.)

[Gdeaver]

This is an area that is a human judgment call. Last year some regionals where very physical and few penalties. At our regional the penalty flags where flying. Every team has to evaluate how far they can go and don't cross that threshold. This years game almost demands blocking strategies.

[Al Skierkiewicz]

To paraphrase a famous quote most judges will tell you "I'll know it when I see it." Not only were penalties given, there existed the possibility of DQ for a match or a weekend as I remember. When a DQ arrives it hurts not only you but everyone you play with in that match. This is a competition to make lifelong friends, don't use it for just the opposite reason.
