You know, like the same number of times crazy triple balance stackers needed to win a blue banner. ;) Given the number of people that wrote that off last year and similar work years prior, better to know now than at alliance selection.

All true enough -- it's just far enough off my radar in terms of what needs to happen in the next six weeks that I'm not going to spend very many brain cells on it. :)

Hey guys I have a ? . Does anyone know if there is a rule for going up the tower to far. As in havering your robot extending past the top of the tower?

I think that this Q&A response might answer your question. There isn't a vertical limit for the field in the rulebook, just the height limit for robots.

From the "Scoring" section of the Q&A

A.There is no upper bound to Level 3.

What Karibou said. However, the sides of the pyramid go vertical above the 3rd rung - a potential obstacle for mechanisms that extend parallel to the climbing portions of the sides.

Re: Climbing Rules
 
I was also wondering if there are any rules for going to high on the tower ? as in you robot extends up past the top of the tower?

Don't CONTACT anything outside of the FIELD

Like said, don't contact the outside of the field.

There was also a GDC ruling on the Q&A that there is no upper bound for Level 3.

Like the roof of the building. ;)

As far as I can tell, there is no rule that says you must be in contact with the pyramid at the time this position is measured in order to receive points.

I realize this is not a common scenario, but we do have a potential climbing apparatus that makes suspension largely trivial, so I'm curious. I'm not claiming it'll happen often, but there were a few suspensions in 2010.

I Q&A'd this and (more or less) the 1/16" ABS sheet "climb" just for thoroughness.

Does any one know if the robot's starting position can have a hook over the 30'' bar?!?!

When placed on the FIELD, each ROBOT must be:

in compliance with all ROBOT rules (i.e. have passed Inspection),
confined to its STARTING CONFIGURATION,
fully supported by the floor, and
contacting its PYRAMID.
So I'm going with no. If it is touching the bar at all, then some miniscule amount of weight is being supported by the bar, violating the "fully supported by the bar" condition. Although it depends on how lenient FIRST is (Q & A maybe). A hook that begins hovering over the bar should be fine, however.

By that reasoning, you can't start a robot touching the outside of one of the corner poles, because the pole would be supporting some small amount of the robot's weight.

I think starting with your hook touching the rung is legal. Or poised over the rung so pulling it in will grab the rung. I'm pretty sure the "fully supported by the floor" clause is to keep teams from starting with a robot already hanging from the pyramid.

Remember that your hook has to be with your frame perimeter in starting configuration. No "mushroom" bots.

Question:

Are bumpers considered part of the robot? i.e. The robot frame is hanging from top rung, the bottom of the frame is suspended just above the middle rung, the bottom of the bumper is hanging just below the middle rung....what zone are you technically in 2 or 3?

Thanks guys...

Today's team update answers that question: yes, the bumpers count for volumetric considerations. (Thus, you'd be in zone two).
