Autonomous in Championship

[Lil' Lavery]

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?

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, it´s 'so crazy', how we used to say in Brazil.

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.)

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.

man...

it´s wonderfull... omg!!!!

but would be better score in the line ^^...

237 will be scoring in autonomous at Atlanta.
