What Are You Doing During Autonomous Period?

Wait, wouldn't that be considered multiple balls in possesion? As in bad?

Because it looks like that from the first part of the defintion for Possesion:

Or if you don't have a suction/roller mechanism, would that be considered okay? (As of the second part of the defintion for Possesion)

How are you detecting a ball?

[nikeairmancurry]

After a few hours of practice, with trial and error, we have come up with a quick efficient method of set-up, drive forward until ball is detected, repeat twice if in the third zone, and so on in the other two zones. In each zone the kicker can be tension differently for a long third zone shot, to an easy kick shot. Lets hope this works just as well at competition, as it has at home.

Oh if your wondering the method for detection, its a secret for the moment. Until we atleast put up some pictures or video.. ^_^

Our robot will try to kick 1-3 balls depending on switches. But technically right now autonomous causes the cRIO to crash. Our Autonomous (like many others I'm sure) is a giant if, elseif and switch-based 353 line state machine. I personally would have rather had it been a series of while loops that go from one to the next, but experience shows the cRIO would crap its self. (And I didn't write autonomous, actually I didn't write anything this year - jus managed made me sadfaced)

i hooked up a switch to the kicker, the robot goes forward until the switch is hit and then kicks instantly, either a soft or hard kick depending on how big the radius of the target is

i dont understand the reasoning behind this, the balls are all gonna have the same radius, mostly around the same size

On behalf of Mechanical MAYHEM (1519), I'd like to wish all the FRC team best of luck with their autonomous modes!

We will be trying to score the soccer balls in our zone during auto. We already have our far-zone auto mode programmed and tested to score all three balls into our goal. We'll be trying to make programs to score from the mid and near zones, also. We're currently exploring the possibilities of scoring zones from multiple zones in the same auto; however, we'll see what's feasible with testing.

Im assuming he means the radius of the FIRST target above the goal..

I'm curious as to how teams are handling the fact that the balls on the left side overlap with the right side of the goal by only a couple inches. Shots will need to be dead accurate unless corrective aiming is done.

I don't it is as big as an issue as it may seem. From our trials, you can avoid this issue. I'm pretty sure you'll see a lot of teams who score from the left side very easily. The center and right side will be the sides to watch.

We will have four options, one for each zone plus a surprise second option for zone 1.
Zone 1.1: Roll forward and kick ball into goal then back off.
Zone 1.2: surprise!
Zone 2: Roll forward to ball, align to target using camera, kick ball into goal, realign, repeat.
Zone 3: Slowly roll forward kicking each ball toward goal, stop after third ball. Hopefully one or more will go in.
