there is no way any one would use a water field the building of the field would have to be perfect if not we would have a real big problem not to mention the damage water can cause i made a sub with a friend the motor got wet and rusted up to a solid peice of junk oh and what happens when the bot is hit and the circut board takes a bath ?

It would be cool, but highly improbable. You need to remember that if a playing field of water was implemented that the rules and limits would probably be changed as well. My guess is if it was a water game is that the 130 pound weight limit would be lifted to something higher for those teams who had the ability to make a submersable, and the cost limit would be higher so that blastic parts could be fabricated so that a mulit directional prop could be produced. Just some ideas of mine. I was told about this the year before last, and did some prelimenary designing and found out how much work it would take just by the designs.

Another note, I don't know if this has already been addressed in this thread...


Playing fields are already expensive, some teams have a hard time coming up with the money to buy the parts for the field as is...now imagine them having to buy a pool. Also, what if a bot takes on water and sinks. How are you going to get it from the bottom of the pool.

grr...
 

sorry folks...water WILL NOT happen....
:) simple as that
unless first makes a reeeeeeeeeeeeeeeeeaaaallllyyy big effort, which they will not do....they have contracts and connections with companies which are basic component companies....if boats and water came into the picture......a whole new kind of kit would haveto be designed, and thats not somethig first would do.....they just rpefer dumping all the old stuff (with some things newer and some taken away) into a box and handing it out......and water when it comes to the construction of the feild would be hard....and expensive......
and there would be too many complications with electronics.....AND.............how do yoy test your bot on a teather ? swim behind it ?
personally i think this topic is getting really old...iv'e seen it around more than once.......................
what it would come down to is the amount of effort and money FIRST would be willing to put into a water competition..........and i dont think they wanto do ither.
:]

IT would be cool.

In theory you could submerge a motor into water and have it still work. Abeit this is in freshwater. Also they make special waterproof motors designed to be waterproof. In theory you could separate the robot and the control/esc's so that they are right next to the controls. Btw there is all ready a competition for water robotics.

Will you guys stop talking about a water competition, you know that there probably won't be one anyway. Besides, water and robots don't mix well.

Sure they do :)

Can we all say thether???

you guys think too hard...water and electronics mix fine...it's the impurities in water that conduct electricity...if FIRST uses pure water it's non-conductive so it shouldn't't have any effects on electrical components. the big question then would be where would they get "pure" water and how would they keep it "pure" through out the competition? I think that water matches, although very cool, may not be in the next year or two.

For the winter Olympics they used "pure" water in the skating rink. If you had a glass of that and tried to drink it, the need for water to bond would rip your teeth out of your head. Anyways, when it would come in contact with the side of the field it would pick up imputities.

Two, it would be way to expensive for lower income teams

Three, as noted-what happens when it sinks?

Four, where could you test it beforehand?

Just stop posting and let this waste of e-space die.

Dream on. Sink like a brick.

Well,.....FIRST most likely already has the game for next year done. If you look at THIS years field drawings, look at the date they were drawn. It was last year or the year before If I am right! But it would be sweet if we did have a water competition. Robots in giant zip lock bags!!

What if someone was eating lunch and the wind blew the salt on his lunch into the pool :) big disaster

a really cool thing to have is floating robots or robots that don't break the surface of the water...weird

If you guys ever get this off, you'd better let me know.

If you guys get shocked, i'll laff !

This is a pretty cool idea. I don't think shorts would be a problem; it's pretty easy to protect your bot against that.

One problem, though, is this: Many teams would want to use their school's pool to practice and test their robot, but the build season is during sim season, so they wouldn't be able to use it during that time of day...

And, of course, the venue problem. I doubt ALL of the Regional venues have pools usable for this. And does the Atlanta venue have 5 pools?
