WOW! THAT IS ALL I HAVE TO SAY!

[DougHogg]

Above is our robot, "Yoda", making 1st contact with the stack in our 1st match and 1st regional for 2003 in Arizona.

In the background, you can see the big screen which also shows our arm and the official clock at 1:58. (Interestingly, the arm on the big screen is lagging a little behind our actual arm.)

It took 59 frames on our video (which is 1.97 seconds at 30 frames per sec.) for our arm to hit a bin in the stack and start it tipping over.

touching boxes is ok I guess, but how long does it actually take you to knock them down?

don't forget how bin placement during hp mode affects your auton

[David.Cook]

If you didn't get to watch the Philly Regional web-cast, check out the Brazilian team (383). They have a pretty fast bar action. One thing they did differently is to deploy the bar, and drive towards midfield to knock the bins down. They pretty repeatably get the nearest four stacks.
Great job guys!

WOW
You acutally touched the boxes in 2 seconds!!!!


Note: Our autonomous mode was evil for the first 3 matches.

I've seen this in action at the Chatsworth scrimmage and it's extremeley effective and super fast (and a little scary when you're a ref and it swings above your head but I'm guessing you fixed that all). Great idea, keep it up and good luck at your other comps!!!

In Arizona, we were "scissoring" the stack (knocking it over starting at one end). Below is a picture of our robot "Yoda" and the stack at 3.5 seconds into autonomous:


The "arm" robot on the left is our opponent, Cyber Blue 234's "Flailer". Here "Yoda" beat "Flailer" to the punch, but I know Team 234 had enhanced Flailer's speed by the end of the Arizona Regional.

I am going to create a thread with pictures from this match of "arm against arm".

We can't forget. I recall how you successfully messed up our autonomous in our second match against you, and beat us.

By the way, I consider our 1st match against your "Flailer" to be a real classic because both arms swung on the stack.

Anyway, we are tied with you guys in matches, 1 to 1.

As to our autonomous, we made some changes in Arizona, as did you I noticed. Also we have been reviewing video tapes of all our matches, and on Thursday, at the S. Calif. Regional, we will be doing some extensive work on our robot and our autonomous.

Maybe we will meet again on the playing field in Houston for another "shoot-out".

Regardless, good luck to your team. I am hoping to see an "arm" robot in the playoffs at the nationals--if not "Yoda", then your "Flailer" or one of the other "arm" robots. (I am still trying to get the video feed to watch Team 71's "Beast".)

It was kinda' scary at Chatsworth. We had to post someone on the side to make sure no one was in range.

We did some major changes after that, including limit switches to prevent the arm from going out of bounds or rotating the wrong way, and it was handled by the Arizona Regional where we were 4th seed and semi-finalists.

As an aside, one day the rotating motor for our arm had a loose connection and the arm came up but didn't rotate. The engineer who designed the arm stepped forward to see what the problem was, when wouldn't you know it, the arm suddenly swung and hit him right between the eyes. He is fine, but he was definitely sore for a few days. I guess there is a lesson to be learned there: loose connections don't always stay loose.

sounds good to me. we'll look for ya there.




COME TO THE IRI

[Pin Man]

Which regional was that? Arent you top heavy with that arm?

[Gope]

Wow, thats fast, faster than Beatty even, but you might be careful with it, our auto mode hits the boxes in 2.75 seconds and Beatty was around 2.5..In the quarter finals at the Mid-West regional we caught their arm on our way over the ramp and flipped them over in auto mode rendering them useless for the rest of the game, be carefull you also don't become the victim of a very fast very low CG robot.
