Collecting 10 Pt. Balls?
 
Well I have not seen any teams do it too effectively, collecting the 10 Pt. balls either in auto mode or during a match. Are there any effective robots out there that can collect the 10 pt balls, and how do they do it?

(PS I thought it was funny how the robot in the kick-off simulation had 2 big hands that grabbed the ball :D )

We are able to grab it with our arm bu it's not really worth the time to do so.

I've been looking at wildstangs robot and wondering if those round things on top were meant to pick up the 10 pt ball. They might have had that features, but decided it wasn't worth it. I may be completely wrong though.

i think any team that has arms can pretty much do it, the only bad thing is that it takes time to allign the arms to the ball and get it out with out knocking it off. it's about the time it takes to get it from the tee to the human player and the hard part is in the goal...

In general, its better to corral two balls than chase after one, unless you are *so* good that you fill up your goal or run out of balls to corral (technokats, im looking at you...). The benefit on investment (in design and implementation) for getting those balls just isn't high enough.

look at that pic both 10pt balls from one side in the goal.. what a move!

If nobody activates the balls in autonomous and you have a ball collecting robot, you might as well try to collect and score the 10 pt balls.

I think it's mechanically possible for our robot to pick the 10pt ball up, and I believe we could write up an autonomous program that would do it reliably, but the robot would have to drive slow since we get the best accuracy when we go slow.

Hopefully we'll have programs at nationals that do something besides sit around for the remaining 12 secs after we've knocked the ball off. We have some cool ones that ignore the ball altogether, but they no longer fit our strategy and we've never run them in competition.

You could always spin in a circle for those 12 secs. I realize it might suck down your battery, but it would be entertaining.

Alternate autonomous strategies include banging into a wall, backing up, and banging into the wall again (repeat). That's the strategy we're working on at least.

We ran that one during our last qualification match at MWR. We knocked the 10 point ball off, drove back towards the movable goal like usual, then took a sharp turn into the outside wall. I guess that's what we get for adding more points to our program without looking them over very closely. One of my favorite programs to run is: drive out, raise arms, get arms hooked on bar, keep driving forward so arm almost rips off :ahh: We ran that a few times during SW development.

We can get the 10 point ball in auto if we ever get our timing right (we put a coating on the wheels to make the bot turn better and the timing is off slightly) - but we can actually pick of the ball off the tee and hold it, then dump it and push it into the ball corral - pics on site if you want to see how we do it - there aren't actually pics holding the ball but you can see the arm the slides under and lifts it up - link to site in sig.

the easy part is to get it in the goal. the drivers just take too much time

I think it’s quit obvious that you all have not seen our robot in action team 1083; we were at the ucf regional and the Chesapeake regional and from the looks of it we look liked the most sufficient ball collector.

Re: Collecting 10 Pt. Balls?
 
I have a question for anyone from Wildstang....what were those cupped things on the top of your robot for? At first I thought they might have been for the 2x ball....but I never saw you use them at MWR...but that might have been because I was driving and never saw any of the matches.

Re: Collecting 10 Pt. Balls?
 
here's my 2 c from what i saw today in practicing at the Can Reg; no one is worried about that one... really I think the beat thing to do with that ball is knock it over with the three starter balls.
