I saw it happen once in NJ in practice - 103 hurdled, the ball bounced and the robot happened to be where it came down, right in their cradle. I suspect their drivers were as surprised as anybody, but it sure looked great.

Team 473 also did this at the Oregon Regional

Re: Knocking off a ball while possesing a ball
 

This actually occured at San Diego today with our team. It was match 29 with blue alliance 968 2543 and 701. Our team (2543) was under the red track ball when we fired our arm to remove the track ball when our alliance member was attempting to place our blue ball on the rack. The refs made the penalty call on our alliance member for such a move (even though in fact it was our team to reomve the ball) and we lost the match. ANYWAY, to make a long story short...

we all entered the challenge box and the San Diego Refs formally announced that it is legal to knock off other trackballs while in possession of your own trackball.

They reversed the penatly on this match and we are still waiting for the rankings to change to say that we won this game. If you look on the first website, our match is missing.

Thank you for "forcing" the refs to acknowledge an "error". Their initial interpretation was a little far-fetched, even for me.

Re: Knocking off a ball while possesing a ball
 

I actually wasn't at the drive meeting when they announced this (though i am a robocoach) but they must have announced it three times that our main ref was led to believe from another above him in a phone conversation that it was illegal. Im just glad they refeversed the call and didn't just decide to change it for future reference.

They updated the matches and list it as 0-0 tie. We watched the video of the match and you can clearly see 2543 knocking it up from below, but then we hit it as we tried to place our ball giving it the forward momentum and hence the "penalty". Moot point though with this rule. The real kicker is why it is called a tie? We won this match after you take away the wrongly called penalty. See the pick...

Should be 48-42 Blue alliance? What did I miss? Oh well - no sour grapes here - just struggling to answer parents and students questions about how and why it was scored this way.

on the screen at the event tonight it showed us 7-0 like we should be. no tie like on FIRST website

Re: Knocking off a ball while possesing a ball
 

I have asked this question on Q&A. I look forward to a quick reply.

It appearsthat we inconstancy across regionals.

Re: Knocking off a ball while possesing a ball
 

I sure hope that the answer is that it is okay to knock the ball off while in possession of a ball, 'cause it was way too cool to watch how some of the teams at St. Louis pulled it off to have it be ruled against now.:yikes: I think I'd be pretty bummed out not to see some of it at the Boilermaker!

Re: Knocking off a ball while possesing a ball
 

Here is the answer that I received from Q&A:

There is no rule that prohibits knocking a Trackball off the Overpass with another Trackball. There was an announcement made at the San Diego Regional concerning this topic that was in error. This was corrected, and the teams were notified of the correction.:)

Re: Knocking off a ball while possesing a ball
 

We were able to knock off the opponents ball while in possession of our ball at the Kansas City regional (see match 19). There was never any mention of this being a penalty. We actually knocked down both red balls during the last seconds of the match while launching ours for eight points.
