To someone who has a manual: how high is the yellow bar from the tip of the ramp? How high is the top of the trough? How wide is the ramp? I haven't been able to reach the FIRST site so I don't know if the field dimensions are up yet. I'm guessing other people face these same problems. Thanks for your help, :-Dan

word on the street is that the field diagram and bom will be up on Monday.
i don't have a manual but what i know is:
top of scoring trough is 6'
ramp is 1' high, 8' wide, not sure of the grade, looks like 14 degrees... 4' base by estimate.

I have the drawing they handed out at the kickoff.

: To someone who has a manual: how high is the yellow bar from the tip of the ramp?
>> 5 feet to the TOP edge of the pipe. Schedule 40 pipe is typically about 1.67' OD.

How high is the top of the trough?
>> 6 feet to the top edge of the horizontal pipes.

How wide is the ramp?
>> It is made of two 4'x 8' pieces of plywood on 2'x12' boards. So it is 8 feet wide and 7'-9' front to back.

Question for others:
Is anyone actually using aluminum pipe. We are still using the steel pipe. It is cheaper and much easier to get.

We are going with steel at the Chief Delphi practice field.

FYI.

We're using PVC pipe for the goals, and steel for the 'hang out'.... hmm.. New suggestion for this year's game name: 'Hangin' Out with the 'Bots'. )

PVC is cheap and light, cheaper than steel pipe I think, and certainly easier to move around. We have to store our apparatus between classes (we teach a robotics class concurrent with the competition, and about 2/3's of the team gets school credit for FIRST, 1/3 volunteer for no credit) Light equipment is a lot easier to move.

Also, what do guys think of the unlimited PVC in the kit? Resiliant and strong.... maybe better than aluminum? With the increased volume we have, PVC might be the material of choice...

If cost isn't in the equation aluminum is your best bet for robot construction. There aren't many structural components on an airplane made out of PVC, and I am sure they investigate strength vs. weight throughly in that field. PVC will fracture under impact loads - more so at low temp.

i have an idea for all non-rookies, and those who has practice areas last year. RECYCLE!! cost-efficent. just think- teenagers are now thinking on the cheap side...maybe its a revolution! FIRST is doing great things!! hehe!

Good suggestion. We just recut the steel piping we had lying around from Ladder Logic 2 years ago. There was enough for one goal and the 'monkey bar,' and about half the needed Kee Klamp fittings.

========
TRY THIS
========

1) take a piece of PVC and hold it at one end.

2) take a 6 year-old style baseball swing against a wall

3) pick up the pieces.

OBSERVATIONS
============

If you plan to hang off that bar, there are going to be a lot of people who dont' want you there. I highly suggest NOT using PVC for anything structural. Especially not if it's external. It works really well for things like conveyor rollers if you're making a robotic vacuum cleaner for the balls. Especially because conveyors are typically internal mechanisms.

We're using steel pipe too. We keep recycling the pipe from the past two years, same with the carpet. It's cheaper than having to purchase new stuff every year. Hopefully, we'll get the credit for robotics this year, but I'd do it anyway!

Yes we are using the good old steel...

I hate to be trite, but I just noticed that FIRST has finally posted its updated field dimensions on the usfirst.org website. But when I saw it, it was only 9:30 my time. So I don't know if anyone else has recognized it yet. Anyway, hope that helps!
