Legality of Team 190's Mechanism?

Maybe I've missed something... I'm not suggesting that the robot does not proceed into Q4, (althogh I think I might have misnumbered in my original post by considering the home stretch as Q-zero rather than Q-1) just that the robot enters Q4 from Q3 by crossing the opponent's finish line before crossing the quadrant line.

Mind you, now that I check thebluealliance in more detail it appears 190 may be finished for the season, making much of this hypothesizing a moot point.

Kudos to them for going with a cool idea. It is great to see teams thinking outside the box. Or, in this case, outside the quadrant!

This would probably run into 80" rule trouble as well as presenting an entanglement hazard in addition to the potential yellow card mentioned by jgannon above.

This video shows their mechanism in action:

Their robot appears to be legal from an inspection standpoint, and should be permitted to compete. However, per <G22>, they should be assessed a 10-point penalty every time their arm extends into the previous quadrant, such as at 1:07 in the linked video. This Q&A response should be nothing new... it only reaffirms the way the rule has been written since kickoff.

there arm doesn't seem to cross any line in a clockwise direction when I saw them on the webcast.

I love the idea though.. I sat there watching going.... "wow..... I should of thought of that"


PS. Doesn't the whole robot have to cross the line before G22 comes into play?? I have seen people drive to the line, have part of them cross it and still back up

Their arm might not, but does their suction device?
Edit: after watching the video Joey linked to, their arm most definitely crosses the lane divider.

I did see that after I posted, I watched the link and it does cross the line (he posted as I was writing )

This is too bad.. I love the design

I have to say, that is a really awesome robot and by far the coolest concept I've seen this year. Especially considering a lot of people on their team have a hard time being able to get enough time to work on the robot.

One of the suckiest robots I've ever seen

Wow. I never realized the effect that crossing a line vs breaking a plane had on 190's design. That does appear to say that 190 should have received a penalty every time they hurdled, for a grand total of -2 points per hurdle. Which is a shame, as I do not think that 190's design violated the spirit of <G22> as the arm was always moving in a counterclockwise direction.

(Hey, finally a positive comment for the SVR refs differing from the GDC is in order for allowing the design!)

This will really be painful for 190 at the Championships. I wonder if they will use their arm in a slightly less awesome way and hurdle while lapping? Anyways, that was one really creative design.

And a disclaimer: I may be a bit biased from being on 190s elimination alliance

That is rather unfortunate for team 190 or rather it sucks like both team 190 and our(846) gripper mechanism. They even got an award at SVR for "scoring while not even moving an inch."
