Robot climbing times

Last season (and I don't know if there was a similar rule off the top of my head about repeated violations) teams would use the strategy of taking a 3 point penalty in automomous to hold and score the extra basketball from the bridge. They were net +3 points. It wasn't considered to be an "intentional" rule violation, but a strategy. It wasn't malicious or damaging, which is what I think the yellow/red card rule applies. If someone intentionally broke the hitting people while in the protected zone rule every match, to cause them to misfeed, that could be considered intentional rule violation.

I believe 341 and/or 67 might have used this strategy last year in autonomous.

Okay, I'm curious now. Got any video?

Most Teams: Can't climb to the top
Average for teams that can: 40-30 seconds
Above average: 15-20 seconds
Out of this world 5-10 seconds

4 seconds? Please.

I disagree. It's completely possible. Not easy, but definitely possible.

I, for one, can't say I would choose a robot which climbed at that speed unless their mechanism was absolutely rock.expletive.solid.

As gabriel pointed out in the other thread... a single bad fall could damage the robot to the point of requiring hours of maintenance to fix... something you just don't have in finals.

Caution never killed anybody. Lack of it however...

I'd think any team building a mechanism to climb that fast would have the know-how to design it in such a fashion to not break.

My bet: more often than not, robots will not be able to climb the tower. Those that can will easily take 30 seconds. The best teams in the world will get under ten. I seriously doubt that anyone will even approach 5, even if you don't count alignment time.

Remember, the hard part of deploying minibots in 2011 wasn't getting them up fast enough. It was getting them deployed quickly. A fast (and reliable) deployment was far more important that a fast climb.

Here's some more food for thought: the first seeded teams would much rather pick a slower team to climb that could always do it (low standard of deviation in score), than a robot that climbed slightly quicker, but couldn't do it sometimes (high standard deviation). Don't worry so much about speed, make a robust and easy to align lift.

If somebody climbs the pyramid in <5 seconds I will eat my tongue. Climbing 100" inches of tower in 4 seconds would require a robot to travel at a ludicrous 2.08 ft/s VERTICALLY WHILE CLIMBING. Ridiculous. The only way I could see something even remotely close to this is if you dedicated your robot to climbing, in which case you made your robot a box on wheels and on which your bumpers and battery weigh more than the robot itself. I'm sorry if I'm coming off harsh, but I don't think it's possible to climb a 9' ladder in 4 seconds unless you're a living organism.

You say this like it's a bad thing.
2012 saw many alliance captains that could only balance on the bridge.

30 points in this game is nothing to sneeze at, and neither is the feat of designing a robot to do precisely the strategy you're belittling.

I'm not so worried about the climbing part breaking, but a bent axle or sheared off wheel on a West Coast Drive is no fun to fix.

OK, I am going to call it right now. No way is anyone under 5 seconds. In 2010, some of the best robots took 2 - 3 seconds using power take-off from the drive train.

All I can say is ... Nessy 2013 is the 4 second legal climb.
