Each team does not need a flag (they just provide their own flag holders), so they don't have to be included in the kits. Each regional competition just has to have an adequate supply of the flags. Let's say they need 24 flags (six on the field, 12 more for the teams in the queue, and six more for spares). There will be an estimated 42 regional competitions next year, but only 10 running at any one time (the flags get recycled from event to event). That means you need a total of 240 flags, for a total cost of $1560.*

Dave makes a great point here (not that he ever doesn't)--flags are an economical choice, definitely for the drastic cost reduction involved.

Now, can anyone meet or beat that $6.50 figure with something more eye-catching than flags?

Thank you, Dave, for pointing out that engineers -- even those who design out-of-this-world gadgets for NASA -- are frugal souls by nature.

This misses the point. A real engineer won't spend money if it can be avoided -- not even sponsors' money.

Why does every team need to have the LEDs in their kit of parts?
How about making a standardised "LED holder" instead of the flag holder. Run an extension cable from the RC "team color" ports to an area next to a square of Velcro in a visible place on the robot (hold the cable on with those adhesive things you can zip-tie cables to). In the queue each team is given an LED cluster box (or two, depending on how many clusters there need to be for the LEDs to be visible) that will attach to the Velcro and plug into the cable extension on the robot. Just like flags, only shinier.

Re: Flag Solutions...

I dont think it would be as safe, but would definetly look cool:
Lasers

I know they have Green and Red, but if there could be some cool way of shinning a light upward from the robot and have it visible, I think that would look awesome. (If there are other colored lasers, or lights [blue and red] , that shine a beam of light visible through the medium of the atmosphere)
Safety though would take another route probably, because of blindness that lasers can cause. Still think it would be a cool idea.

Re: Flag Solutions...

Colored LED lights...

Re: Flag Solutions...

I'll chime in for solutions that hold the flag more securely. The ramp bots especially had trouble holding onto their flags at the end of matches. The flags are actually more visible and cheaper than the lights we have tried over the years, and a lot easier to replace when they break and the lights were always breaking.

That the GDC can decide whether the team has to or doesn't have to use the flag. Same idea as the bumpers, you can use this thing and have this advenge by using it but you need to make it to this exact specification. That way FIRST doesn't have to pay for it and it is a standardized way of doing something.

When you start making rules which allow teams to make up their own rules, all such rules (and rules about making rules) become irrelevant rules. :eek:

From a refereeing standpoint, you need a unified system to identify robots. Allowing teams to make up their own methods would prove overly complicate the job of refereeing. And from a judicial standpoint, I think the GDC would have better questions to answer during the build season than 1500 teams all asking them if their own system of identifying themselves is adequate.

As Dave said, all potential "solutions" have to solve all the current issues and do so better than the current choice of flags. While we may not always enjoy the flags, it's hard to beat flags when it comes to being cheap, easy to change before each match, allows for standard and easily visible robot/alliance identification, and allows for the addition of yellow flags. Unless there is a better solution for all of those characteristics, the flag will stay.

Re: Flag Solutions...

Art- First of all I am bad with words, so bear with me.

I think you misinterpreted what I was trying to say. What I was trying to say is have a rule for a robot identifier that teams can make themselves. It would be like the bumpers, if you want to use them then you have to follow strict guildines. This way you have either a flag or a what FIRST would say teams can make.

If it is the same way the bumpers are then you can only make them one way. I have never seen a team use 3 pool noodles in their bumper. I don't think anybody has. why? It is against the strict bumper guidelines.

Let me know if you understnad better now.
