Re: Are extensions with bumpers after the start of the game legal

Actually, Jesse, I think no penalty. <G61> is my witness on this. Repeatedly doing that, you might be at risk of a yellow card (repeated egregious behavior--being continually turned into the zone) under <T06>, or penalized if you aren't quick enough to pull out. Trust me, high-traction wheels aren't quite a sure anti-turn method. It may just make the turning uglier to look at.

Given that you fit in the 84" diameter circle, I'd say legal, but risky. I can see a few ways to get a robot past you and score. Based on the top-view drawing, you'd be at 85" and change given a full 38" long starting robot, excluding the bumpers on the extensions (83" given a 37" long starting robot, which is recommended, and definitely over with the end and side bumpers on the extension--92" on a 37" robot base), measured corner-corner because that's the easiest way to check fitting in the cylinder. The cylinder, like the sizing box, is unforgiving. It may help to draw one up in your favorite CAD program and fit the robot into it, if you haven't already.

Sandbags: There are other ways to add weight. If there's any hole in the sandbags, and any sand gets out onto the field, you could be penalized under <G45> (damage to arena by sanding) or <R31> (I know it says lubricants, but it could easily be extended to other contaminants--in fact, it used to include all contaminants, but that's not quite relevant this year because that's past years' rules). Try steel plates instead--they're fairly easy to bolt on, and smaller in size, and won't get all over the field if they come loose.
