Speeds

Uhh, lol, that really depends on which material we have on our treads. But, A rough time of 10 seconds to be at the top of the ramp is fairly close.

well,its not exactly a great time, but i guess u guys are planning on moving around during the match, or are u gonna sit on the ramp?

Movin around

of course. we can either sit, or move around a lot. We dont plan on being a punching bag this year, were going to play each match as we get it. That's up to the strategy section of our team.:D

Thanks!!

I am sure Denny and I will be more than busy throughout the competitions as well as any down time. Wish Phil was around for this great season!!

All you have to do is just make sure that Big T3 truck is done!!! ;)

T3!!

Thanks to all of the teams who have been checking out our robot! We are very proud of our bot this year and hope that we can take it great places. It is comments like yours that help us determine our strategy. Hopefully everyone else this year is as proud of their robot as we are about our own. GOOD LUCK AND CYA SOON!

~Lauren~

Go out there and kick some robutt!

Nice looking robot; hope you have lots of spare arms because the judges won't really be strict against teams trying to push something that covers the field...

Oh yeah, read this too:

I can tell a lot of teams will be starting to upload teasers and other images of their robots soon.

PLEASE upload these to the picture gallery, rather than attaching to a post. I'd rather have apache handle serving the images, rather than mysql. The database backup process also thanks you.

Once your image is approved (shouldn't take a long time to get approved) you can then reference the image in the gallery with vbCode [IMG ] tags. You either have the choice of starting a thread in 'Robot Showcase', to show your robot -- OR -- let someone start a discussion via the picture gallery.

Thanks,
Brandon

Your limbo bar setup is illegal.

Quote:

From the FRC Forums
Q. To what extent can parts of the robot contact the midfield barrier?

Jan 23rd
A. GM 28 prohibits "attachment". GM31 allows incidental contact. A trip device to lower or displace the rotating beacon is allowed as long as the lower bar itself is not used to force the light down to get under the bar. Any intentional hard contact with the midfield barrier is prohibited. The midfield bar was not intended to support or furnish a reaction surface for the robots. It is intended to demarcate the midfield and prevent containers from being slid from one side of the field to the other.

Jan 20 (diff, but similar question)
A. See Rule GM31. You can touch the midfield barrrier but you cannot react off of it. You can step over it. you can go under it. If, in wrapping around the pipe barrier you rely on it for support, you will be penalized.

Jan 20
You may contact the barrier. You may use the barrier to detect it or locate it. You may not jamb containers or robots under it. You may not react off the bar. This means that you may not purposely push off it to gain an advantage.
You may not use the bar to force your robot to decrease in height ( i. e. compress springs to make the robot low enough to go under the bar)

By this rule, you are reacting with the barrier. Your limbo mechanism is purposely pushing off the barrier to gain advantage when a robot runs into it. Incidental contact is okay, but reacting on it as you are is illegal.

As posted earlier our robot's arms dont actually touch anypart of the side bars or the plexiglass. The rule states to touch with the intent of supporting your robot and we have all of our support on the HDPE. We have taken into consideration many different aspects of contact and have cleared all of them. It will be okay...

Thanks for your concern.

Lauren

OK not breaking any rules there....

Quote:

For the first one: the contact with the bar will be incidental on the part of our robot. If another team pushes us into it, there is a major difference. We are not intentionally doing anything it will be other teams on the field that make us touch it.

For the second one: we are not wrapping around, the maximum that our robot will ever touch is on one side and that is the result of another team pushing into it.

Hard words coming out.....

Read the bold text.

When a robot hits your "mechanism", it will hit the midfield barrier, thereby reacting against it purposely. It's pretty obvious this mechanism is intentionally designed to react off the barrier to gain advantage.

The question you have to ask yourself is this: If the midfield barrier weren't there, would a team still be able to get by? If the answer to this is yes, then you are relying on the barrier, thereby purposely reacting on it.

I doubt you can answer no to that question because those arms are a very, very long lever. There's virtually no drivetrain that can push against that 12'+ lever.

There's no difference between this, and grabbing a goal in last years game, and having a mechanism that sticks between two field poles and saying, "Oh, we're not touching the field poles, but if someone pushes us, that's their fault."

In the end, it will come down to the referee ruling at the competition. We'll just have to wait and see.

IMHO, it's too cool of a design to be illegal :)

Mark Garver

20-02-2003 22:26

OK...

Still we can argue that a downward force is on each of those legs.

Perhap's the "Tether Rule" may be subjected here. Where as the illegal items become legal because there was a lot of engineering effort put in. Who knows, I agree that it will be a ref's decision.

I hope they stop this problem before it starts, otherwise teams will be adding mechanisms to take advantage of this loophole.

Kinda like filecards and tape measures last year. Everyone had them after they found out they were legal.

Then FIRST tried to crack down at Nationals but by then it was too late, everyone had them.

All times are GMT -5. The time now is 23:38.
