Flipping bots
 

I was thinking, is it possible to make a flipping bot, that will start the game up against the driver station, and flip immediately, thus using the 20'' extension constantly. (style team 16 in 2008).
I read the manual, and it's kinda vague for me if that's OK or not... will this require any unique bumper design?

G20
ROBOTS must be in compliance with Section 4.6: BUMPER Rules throughout the MATCH.
Violation: DISABLED


R22
BUMPERS must be located entirely within the BUMPER ZONE, which is between two (2) and ten (10) in. from the floor, in reference to the ROBOT standing normally on a flat floor.


You could, but you would be disabled

There is something like a 10 sec to right. If you could swing the bumpers into correct allignment in that time, I suppose it might be allowed. Godd question for Q&A?

I'm too lazy to quote the rule, but you can't articulate bumpers. Its a rule every year.

EDIT:

Re: Flipping bots
 

Uhhh... No. There isn't. No grace period to get bumpers in compliance. You gotta start with everything inside the Frame Perimeter, too--which is exactly where the bumpers are attached, and no you can't articulate those.

You're thinking of the case where a robot has gone over, where they have 10 seconds where opponents can't touch them. (G30)

Re: Flipping bots
 

3.2.6.4 G30
Fallen (i.e. tipped over) ROBOTS attempting to right themselves (either by themselves or with assistance from an
ALLIANCE partner) have one (1) ten (10)-second grace period per fallen ROBOT in which the fallen ROBOT may not
be contacted by an opposing ROBOT.
This protection lasts for either ten (10) seconds or until the protected ROBOT has completed the righting operation,
whichever comes first.


So logically if I could swing my frame (including my bumpers) into the right position relative to the rest of the robot, then in theory, I have violated the rules unless there is a rule against intentionally tipping over.

Re: Flipping bots
 

So it really depends on if you are deemed to be blocking the field or not.

Re: Flipping bots
 

Both incorrect. We'll skip blocking the field for now, and focus in on the "flopbot"--also note that blocking the field shouldn't be an issue unless that 6" goal blocker is out to full extent. Noting first that there's a perfectly legal alternative--namely, dropping extensions and not pulling them back up--the crux of what makes the strategy illegal has to do with the bumpers and the Frame Perimeter. And, in fact, the SECOND rule in the Robot section immediately makes the proposed bumper frame idea illegal.

As we all know, the Bumpers must be within the Bumper Zone at all times. I'll hold off there for a moment while I go through the rules a bit further.

Next up, the Frame Perimeter, which is determined in the Bumper Zone. In other words, the Frame Perimeter, as determined by the normal configuration of the robot, must be able to be against a wall, or close enough to it.

Per R22, So far, the bumpers must remain in the bumper zone, which is parallel to the floor, and they must be mounted on fixed, non-articulated structural elements of the robot--and, to start out, the robot needs to have nothing outside the frame perimeter. I'd add in R23, but that one specifically calls out that it's with reference to the Frame Perimeter--which I've already established as having to be non-articulated.

I think that's enough to show that flopping down to start the match is impossible to do legally. 16 was able to do it in 2008 because of somewhat relaxed (and still in flux, to some extent) bumper rules--but unless those relax, 16 is the very last team to compete with a flopbot.

About that blocking the field--I'd consider that to be the least of my concerns, unless I actually had a goalie pole that was out when I flopped over. 50 points can be overcome, if assessed--but not with a disabled robot (G20, for violation of bumper rules) or down a robot (T6 and T7 require you to not show up if you haven't passed inspection, under pain of alliance red card and you not being allowed to compete until you've passed).

Re: Flipping bots
 

...and some pretty animated discussions with robot inspectors. (We love you, Al.) Having the last flopbot is a sad distinction.

Re: Flipping bots
 

Atleast the rule isnt called Rule 16 in the rulebook. lol

Re: Flipping bots
 

Sorry for being in the dark here, but what is the advantage of a flip bot? I tried looking for some matches on the blue alliance with team 16 and I saw the Curie finals and saw them against the wall then come down but I don't understand why this helps except for not being outside the bumper limit? Now I understand, is it so that you can extend out and since you are in the goalie zone it can be as far out as you want?

Re: Flipping bots
 

The 2008 balls were about 40" in diameter - much larger than this year's. We wanted a robot with a footprint that was larger than the starting size allowed in order to carry the ball. With the rules that year (sort of) we were able to stay in the correct size box in our "starting configuration" and flop to our desired size for game play.

Re: Flipping bots
 

Ahhh ok, I understand now, can't say I'm to surprised Your team came up with this, can't wait to see what yall do this year at AR regional!

Re: Flipping bots
 

I think we generated several rules that year...sigh.

Re: Flipping bots
 

16 wasnt the first to build a "flip bot."
