Hi all, time once again for the question of the week:

Question 8/20/00: Do you think that having water as a playing field would be a good idea?

Water as a playing field would definitely be interesting. There might be problems with keeping the water level constant because aggressive play might causing some splashing...I think that FIRST could do it though...the old carpet is great, but water would be a tough new challenge.

Oh Yeah!

Driving robots in or under water would be the ultimate competition. I have been wishing for a competition involving water ever since I have been on a FIRST team.

I think the swim team would get a little miffed at having to share the pool.

Diving Robots, that would make a splash with the media.

First they want me to wire everything and have it work correctly and not short. Now they want me to waterproof it too. What next? EMP shielding? Except for the fact that our robots are electrically powered, I would think that water would be a good idea. Otherwise, no, I have enough trouble already.

I think it would be fun. But in 6 weeks I don't think many teams could field a competitive robot, much less test the one they have. Getting the robot to remain stable while trying to score would be difficult. And scoring would be low because the robots could not move as fast in water.

But if FIRST could figure out an appropriate challenge, I'd be in favor of it.

In theory, yes, I like the challenge...in practice...eeek! Trying to waterproof everything gives me a large headache! I have to agree with Matt on this one!

I am pretty sure that my hat is safe on this one:

I will eat my hat if FIRST will ever goes to a water based field.

Joe J.

P.S. All bets are off if FIRST forms that pro-league I am always lobbying for ;-) Although I wouldn't mind eating hat stew every now and again if it helped bring about a pro FIRST league.

We all no how to play on carpet.. on little square and hexagon fields... i would hate to say it's getting a little predictable.. as are we...

So why not make a competition where past experience doesn't really matter.. where the master crab of the Delphi may not be applicable, the speed of Buzz would need to happen on something other than wheels.. where Assabet would be challenged to put out a quality bot (personally, i think 157 has quality robots down to a science!)

Maybe water's a bit drastic for 2001... or maybe it's not.. I'm ready for the challenge.. I'm ready to have to convert the wheelchair wheels into propellers.. i'm ready for it to be HARD to score.. HARD to play the game... not to say that the game's we play are easy, but so much of it we already know how to do (half of us could build everything except the pickup device before the six weeks.. and the only reason we couldn't put in pickup is cause we wouldn't know the size of what we're grabbing)...

And who are we as FIRSTers to say it won't work, it can't happen, and we don't want to have to learn how to make it happen!!... Motorboats work... i haven't a clue about waterproofing electronics.. but heck, i think it would be fun to learn.. it's been a few years since FIRST has made me learn something new.. or look at something different...

Think of Maize Craze.. a corn bed... i bet people thought that was 'impossible'.. couldn't happen.. was too hard.. etc... but 28 teams didn't see it as such.. heck, on my old team, they built their robot after a kid who worked on a golf course said 'hey, you know those little trucks they drive around to pick-up the golf balls.. hey maybe we could use something like that..'...when's the last time many of us had to think like that??

I'm not meaning to offend anyone.. and maybe i've trailed off the subject a bit.. but there isn't anyone who can't say the game hasn't become a bit predictable.. we know we'll need wheels, need to lift something.. etc... i would LOOOOOVE to see a major change in the game.. water, corn, marbles, sand.. whatever! Don't say it's too hard.. that's never an excuse.. and don't say it wouldn't be fair to the rookies, because that is the only way to make the game even slightly fair.. the less FIRST changes, the less we have to change our previous year's robot.. the more advantage any multi-year team has...

Let's completely revamp the game... after 5 years, i'm being to yawn a bit :-)

Note: Don't take the following as a commentary on the future of FIRST games, just a comment about the past.

I competed that year and the corn was _very_ difficult to deal with. In fact, it took us about 3 weeks and a ton of experimenting to design a good drive train. Corn gets between chains and sprockets and either wedges them or causes the chain to slip off. The same thing goes for pulleys and belts. Two-wheel drive is not an option because of the resistance of the corn. Normal and really wide wheels just sink into the corn and spin, like a car stuck in mud or snow. Wide treads have the same problems as pulleys and belts plus they make it really hard to turn. The first drive system we developed that actually worked was a set of four 'paddle wheels' that would churn through the corn like the paddles on a riverboat.

We ended up designing tall thin tires that cut through the corn to the plywood below, had rubber tubes around the perimiter for traction (tires). We powered the front wheels from the motors and the rear by a narrow, round belt in a wide grooved pulley which allowed the corn to flow around the belt without lifting it out of the groove.

Other teams that I remember: Nypro had a cool design with what appeared to be about 20 wheels on 4 axles that not only propelled the robot but also picked up the balls, and the Technocats had a really light and fast robot that ran around on top of the corn with spikey aluminum spokes that approximated the shape of wheels.

All in all, it was very satisfying to come up with something that worked well, and very interesting to see all the different designs. However, many teams struggled and never came up with a good solution. Also, the corn had to be raked into a smooth state before every match, which slowed things down.

One amusing benefit to the corn was that a Physics professor who helped on the team got to take home all the corn from our practice field once the competition was over and feed it to chickens he kept on his property.
