Autonomous in Championship
 
Hi, I am a brazilian mentor of #1860 team and, i would like to know the teams that are scoring in autonomous mode and it will participate of the championship... If possible, post the some link with a video... I think that is important to know the robots better. Thank you by everything, mainly by the support to the Brazilian teams every year.

PS - our autonomous: http://www.youtube.com/watch?v=0_NWM2OEfI0

1038 will be attempting to keep our string of pretty successful autons alive in Atlanta. I don't have a video, but I have a few pics of our set up and the end result.

Hi,
648 will be scoring in autonomous at the championship, and hopefully trying a more complex "secret" autonomous mode.
Here is the link to a few of our autonomous scoring matches

check out qf1m3, and sf1m1 and sf1m3. For a laugh, check out fm3, and il_019
good luck at the championship

Man...

Imagine an alliance with three robots that scores in autonomous. You start the match with 2^3 points.

Itīs craaaaazy...

In the eliminations at Buckeye, we had two that could score well in auton, 1038 and Sparx... We tried to do a double auton hang on the same column (top and middle legs) twice... didn't work real well due to interference between the robots and the rack. If you could time it right, it would be way cool. As it was, the place went nuts when both robots took off towards the same target.

Yeah, it was awesome. In Q4-2 Sparx scored auton on the middle and we missed the top, and in Q4-3 Sparx missed the middle and we scored the top. It was great to see.

Hey dan...

This problem we obtain to solve. After the competition, we change the programming in order it scores in an spider leg without target. :D ...

It would be surreal if it happened this in atlanta.

Man... omni wheels is nice...

and your autonomous is very effective, but, it can put in lower leg?

116 scoring in Auto

1114 and 67 scoring over each other
Simbots and HOT do it again

How many teams are going to try to score on the leg NOT directly in front of them? We're using a gyro and encoder to give us the option of a side score, but I haven't seen anyone successfully do it yet.

Donut...

We use encoder and gyro too, but when we start to test the correction of angle, the gyro did not function very well, then we decide to use the camera for give us feedeback. In this way we obtain to score of any initial position.

330 managed to do that once. Dead reckoning works sometimes (in quals and eliminations, I've seen 3 from us in two regionals, plus a bunch of near misses).

Somebody saw in some regional a robot that scored in spider leg without target? :confused:

Yes. A few teams have done it, including 116 and 330. Granted both of these teams weren't using their camera for their autonomous when they scored. The video I posted of 116 scoring earlier actually shows us doing it.

I had not repaired that you placed in spider without target. But congratulations man, itīs 'so crazy', how we used to say in Brazil.:D

These prizes only emphasize the great mind that is behind all this work.
And I own a lot from what I am today, because of this mind ^^
I belive you know what i'm talking about!

Were you using dead reckoning and got lucky, or did you use other means of finding the rack (like ultrasonic range finders)? I have ultrasonics, but am having problems programming them. Perhaps you have some pointers?

When we scored, we didn't have any sensors sensing the rack, at the time the only functional sensors on our robot were our gyro, arm potentiometer, and accelerometer. We do have an ultrasonic sensor on our claw, and we are trying to incorporate it (as well as our camera) during the fix it window. We haven't had any real time to play around with the ultrasonic yet during the fix it window, but if we do, we can probably offer some tips.

Dead reckoning. If you're at the championship, look right under our controller for our straight line device (IMU) and at our drive chains for a set of potentiometers--then try to find a camera on the robot. (There isn't one.)

Not omni-wheels, crab steer, all for wheels are steered so we can go sideways. Putting on the lower leg is just a matter of a couple-few different values. We might end up having that option at nat'ls.

It is so great to see all the good autonomous modes, especially two teams same time.

1902 will be in Atlanta delivering on autonomous, we did 13 of 16 times at Florida.

See soap video in QF (takes awhile to download)
http://www.soap.circuitrunners.com/2...l/fl_qf3m2.wmv

See youtube of our practice.

Looking forward to Atlanta and doing auto mode with some of you.

Re: Autonomous in Championship
 
After burning our fix-it-windows for this week today, we successfully fixed all the problems the camera portion of our autonomous code was having. Our gyros and encoders work, our camera works, and our arm worked before our Regional ended, so I'm happy to say that we will officially be scoring in autonomous at the Championship.

We're going to try to actually mount an arm on last year's robot and get a keeper scored with our last fix it windows next week.

hey doug...congratulations man, your bot is great...I hope to find your team in a same alliance in atlanta. ;)

see ya

Team 1425 scored in auto mode using ultra-sonic sensors in the Las-Vegas regional. We didn't get our auto-mode working until the last 2 qualifying rounds.

We use 4 ultra-sonic sensors and do not use the camera. We have one that looks for the rack to determine distance, and 3 that look for the spider foot to line us up. Thus we don't care about the presence or absence of the light.

Check us out on the SOAP archive of the Las Vegas regional.

We will be in Atlanta (due to our win in Las Vegas and a very successul fund raising effor <THANKS XEROX!> ), we are finalizing things this morning.
