Climbing Mechanism Ideas

That would now be worth points for robot B, as it would now touch the levels in order, until its final spot, making it a valid climb.

1) The floor is level 0; not the footings of the pyramid.

Where did you see this in the Q&A section? No one on our team can find this question / answer.

Thanks

I would guess they were referring to the January 8th team update for this part:
http://frc-manual.usfirst.org/Updates/0
The specific quote, with new text in bold.

A ROBOT has CLIMBED its PYRAMID if it contacts the PYRAMID and/or the floor (Level 0) in

sequential order (Level 0, 1, 2, 3) during ascent and
no more than two (2) Levels simultaneously.

This seems to clarify that level 0 is indeed the floor. I hope that answers your question!

It's just not worth any points unless after leaving level 0, the next level you contact is level one.

While true, the rules do not currently require you to contact any level besides 0 in order to receive climb points. (Sequence = 0 and Max Simultaneous Levels = 1, then climb legal and credit given by lowest point on robot)

There'll be a Q&A question to by this afternoon at the latest, so no need heat up the debate too much. Anyone interested in suspending, stay tuned.

We are working on our robot design ideas. I was wondering if this idea would work.
Our idea is to have three arms. Two are going to grab onto the bar while the third keeps it in place. We want to get to the third level then dump four of the color frisbees in. Any ideas to help with the design? We need an idea for how we are fully going to climb the tower.

What Siri says. There's nothing in the rules that says you have to touch a particular level before you can be scored in that level. This interpretation assumes that if you're only touching the floor, you have a valid climb. Then you proceed up the pyramid and have the chance to invalidate your climb by breaking one of the two climbing rules. Once you invalidate your climb, you have to go back to the floor as the starting valid state.

The opposing interpretation implies that you have to actively fulfill those two rules to create a valid climb. Which raises the question of whether you have to climb all the way to level 3 to create a valid climb, since the rules don't mention anything about stopping.

I still like the 2010-esque latches (that can move out of the way of the horizontal crossbars) for this, but I don't even know how I'd know if they damaged the powercoat until competition time. Heck of a thing to be find illegal and lose 10-30pts/match over.

Our team might have our tower powder coated. I'll have to mention testing some of these things to the mentors. Most likely we're going with a non-clamping design.

Here is our plan that we are trying to flesh out

Hope it works

Ok, I don't mean to picky here, but I just realized what might be a problem. Imagine a hook that fits on the bar. Since the hook is touching the top of the bar, and the middle of the bar, this hook is touching the pyramid in 2 levels.
If you had hooks of any sort that pulled you up with say, something holding you on a lower bar, 1 level, and the one above is hooked on a bar, you are in 3 zones, if only by the quarter inch thickness of the claw.........

Any thoughts? Would they be this picky in the rules?

Thanks
Mike

The bar counts as being in the zone below it.

You can only not CONTACT more than 2 levels at once. You can OCCUPY as many as you'd like.

Ok are team is at a bit of a standstill on climbing. We realized that our climbing idea won't work because of the rule that says we can't extend outside a 54" cylinder. So we decided to figure out a way to go up the corner legs. Any ideas?

We're trying to do what some teams did for 2010, with a grab and turn mechanism. We grab onto the pole, flip, and with a second arm, grab, flip, and repeat until we get up to the top.

Climbing seems much more difficult than we anticipated.
Our strategy put climbing ahead of shooting, but I'm beginning to think that that wasn't the best idea.

Anyways... No one I've mentioned this too really likes my idea but it goes like this...

I simply use a spring loaded a "jumping" mechanism that would catapult my robot towards the top rung. While in mid flight, the robot reaches out and briefly touches level 1 and 2 in that order, then grasps on to the top rung.

I enjoy imagining what would happen if it misses...

I'm enjoying imagining the look on your Lead Robot Inspector's face when you tell him that.
